What is a Zune custom class?[edit]

A Zune custom class is a newly created Zune class based on an existing one. A custom class may provide improvements or changes to the one it's based upon, thus extending Zune.

Zune custom classes are identified by the suffix ".mcc".

AROS' Zune classes (including supplied custom classes) are located at SYS:Classes/Zune.


Mui Custom Classes (MCC) some of which are closed sources.

Examples of open sourced ones...

http://www.jens-langner.de/dev



Using custom classes[edit]

Here is an example how a private class is defined:

extern struct MUI_CustomClass *FPEditor_CLASS;

/*** Macros *****************************************************************/

#define FPEditorObject BOOPSIOBJMACRO_START(FPEditor_CLASS->mcc_Class)


Some custom classes are supplied with AROS. Others can be installed into AROS. Others can be loaded from disk.

Custom classes usage in your application is mostly straightforward (just like any built-in class). The only prerequisite might be including the appropriate #include-file.

For example: If you've been using the (built-in) "Text" class/object of Zune...

#include <proto/muimaster.h>
#include <libraries/mui.h>
...
   TextObject,
      MUIA_Text_Contents, "hello world",
...

...you may use the custom class "TextEditor" exactly the same way, just add the proper include-file and adjust the attribute (MUIA_...) to match the new class:

#include <proto/muimaster.h>
#include <libraries/mui.h>
#include <mui/TextEditor_mcc.h>
...
   TextEditorObject,
      MUIA_TextEditor_Contents, "hello world",
...

Another example is the "NListview"/"NList" class, which is an enhanced replacement of the (built-in) "Listview"/"List" class. In this case even the custom classes' attributes match the original classes' ones.

Of course it all depends on the way a custom class is built - it might introduce completely new attributes or method. In any case it is strongly recommended to obtain a custom classes' developer documentation of attributes and methods.


If you have a custom class,and this should have an extra attribute, which needs to trigger via a Notify-method. You simply need to forward the OM_SET message to your superclass.

struct TagItem *tags, *tag;

for
(
tags = message->ops_AttrList;
(tag = NextTagItem(&tags));
)
{
switch (tag->ti_Tag)
{
....
}
}

return DoSuperMethodA(CLASS, self, (Msg)message);

If you want the app to be able to check the attribute via a Notify that is setup at progstart. Than you want to set the attribute inside the class, and the app should react according to that notify.



Reference[edit]

BetterString[edit]

Can scrollback buffers be achieved with betterstring.mcc? Yes, simply subclass it and add an eventhandler with priority above zero, and react on the arrow up/down keys. My idea for an API would be a method a la MUIM_BetterString_Freeze, which would add the contents of the current buffer to the history. Normally one would then setup a notify to let MUIA_String_Acknowledge trigger this method. Additionally there should be a tag to force moving to a certain buffer.

If you do create a buffer-system, please let the Freeze-method verify that the buffer has changed, and only add it if so - there's nothing as irritating as the unix shell which keeps adding repeated commands to the history, so that one has to press arrow-up a zillion times before getting to the previous *different* command...



NList[edit]

It is more powerful, as it supports horizontal scroll, clickable titles, re-arranging of columns, re-layout of columns etc. - but most consider it more complex and not as fast plus it has a few flaws.

creating your list like so

MUIA_NList_Format, "BAR,BAR,BAR,",

That will give you a four column list, each column separated by a vertical bar. Add or remove 'BAR,' entries to the desired number of columns. If you have enabled the titles (a good idea for multi-column lists) then you should also ensure that your display hook sets the titles for each column.


For sorting you must supply MUIA_NList_CompareHook (or overload MUIM_NList_Compare) to get proper comparison. The default comparison method works only for single column lists with plain string pointers.


How to tell if a certain entry is in the visible part of the NList then? You can calculate the visible entries using: MUIA_NList_Horiz_DeltaFactor, MUIA_NList_Horiz_First & MUIA_NList_Horiz_Visible.


If you are using custom data structures:

  • Display method/hook is required.
  • Compare method/hook is required if you are using sorting.
  • Construct/Destruct is optional, to temporary copy these structures or whatever you want.

If Construct/Destruct are missing NList.mcc will pass entry which you inserted directly to f.e. Display/Compare/Destruct.


Procedure with variable amount of parameters in aros, and some damn macro... here is a valid and working procedures, resolves some problems with "End" macro, and implementation of DoSuperNew

IPTR NewObjectAROS( struct IClass *classPtr, STRPTR classID, ULONG tag1, ... )
{
AROS_SLOWSTACKTAGS_PRE(tag1)
retval = (IPTR) NewObject(classPtr, classID, AROS_SLOWSTACKTAGS_ARG(tag1));
AROS_SLOWSTACKTAGS_POST
}

IPTR DoSuperNew(struct IClass *cl, Object *obj, ULONG tag1, ...)
{
AROS_SLOWSTACKTAGS_PRE(tag1)
retval = (IPTR)DoSuperMethod(cl, obj, OM_NEW, AROS_SLOWSTACKTAGS_ARG(tag1));
AROS_SLOWSTACKTAGS_POST
}
IPTR DoSuperNew(Class *cl, Object *obj, Tag tag1, ...)
{
  AROS_SLOWSTACKTAGS_PRE(tag1)
  
  retval = DoSuperNewTagList(cl, obj, NULL, AROS_SLOWSTACKTAGS_ARG(tag1));

  AROS_SLOWSTACKTAGS_POST
}

or in a more portable manner

Object *DoSuperNew(struct IClass *cl, Object *obj, ...)
{
    Object *rc;
    va_list args;

    va_start(args, obj);

    rc = (Object *)DoSuperMethod(cl, obj, OM_NEW, va_arg(args, IPTR), NULL);

    va_end(args);

    return rc;
}
DMethod(my_listview, MUIM_NList_ReplaceSingle, "foo", MUIV_NList_Insert_Active, NOWRAP, ALIGN_LEFT); 
DoMethod(my_listview, MUIM_NList_Redraw, MUIV_NList_Redraw_Active);


I intentionally ignore __stackparm in the prototype because it has no meaning for PPC and x86-64 at the moment, and it never had it for i386 and m68k. When the preprocessor expands macros on i386 (or any other architecture which puts all arguments on stack). the code is turned into this:

IPTR DoSuperNew(Class *cl, Object *obj, Tag tag1, ...)
{
  IPTR retval;
  
  retval = DoSuperNewTagList(cl, obj, NULL, &tag1);

  return retval;
}

If you declare the function static, gcc's extremely-clever-award-winning-supper-dupper-mega-ultra-optimizer looks at this and decides that the function uses only its first tag1 argument. And calls like:

 DoSuperNew(cl,  o,  MUIA_Foo, MUIV_Foo, MUIA_Bar, MUIV_Bar, TAG_MORE, morecoolstuff)

are turned into: DoSuperNew(cl, o, MUIA_Foo)

Which in fact cause undefined behavior. In most cases FindTagItem() browses stack contents until it hits zero longword occasionally appeared somewhere, so you notice almost nothing. In some cases this can cause memory trashing and illegal address accesses.

Perhaps a more future-proof solution would be to use va_start() and va_end() macros. On architectures we talk about va_list is simply a pointer to current argument (i. e. in our example it will be &tag1 right after va_start()).

IPTR DoSuperNew(Class *cl, Object *obj, Tag tag1, ...)
{
  IPTR retval;
  va_list args;
  va_start(args, tag1);
  
  retval = DoSuperNewTagList(cl, obj, NULL, args);

  va_end(args);
  return retval;
}

NList.mcc

This MCC public custom class is very similar to the MUI's list class. It handles directly most attributes which are handled by Listview in the original couple List/Listview. The NListview exist anyway to provide a complete object with scrollbars, so you should use it as child of NListview. Anyway, you can use NList without NListview if you don't want any builtin scrollbar. 

NOTE: NList class will not work with Listview without some conflicts, and NListview class can't use List as child but only NList or a NList subclass.

MUIM_NList_TestPos and MUIM_List_TestPos are similar but use a different struct to store data.
MUIM_List_TestPos works like with a List object.

NOTE: Avoid as possible to do many things in MUIM_Show and MUIM_Hide methods because when an object is in a virtual group, your object will receive them for each one of its moves !!!

Standard tags with NList special values :

MUIA_Background   has the same meaning than MUIA_NList_ListBackground but only at init.

MUIA_Font         is settable only at init. MUIV_NList_Font, MUIV_NList_Font_Little
                  and MUIV_NList_Font_Fixed are special values usable for it (settable in prefs)
                  but standard values are usable too.

MUIA_Frame        you can override the defaults frames of the classe by setting it, but it will
                  be overrided again by defaults if a set(obj,MUIA_NList_Input,bool) is made after.
                  if MUIA_NList_Input is TRUE then the default is MUIV_Frame_InputList, if FALSE
                  it's MUIV_Frame_ReadList.

MUIA_NList_Active -- [ISGN], LONG

        MUIV_NList_Active_Off
        MUIV_NList_Active_Top
        MUIV_NList_Active_Bottom
        MUIV_NList_Active_Up
        MUIV_NList_Active_Down
        MUIV_NList_Active_PageUp
        MUIV_NList_Active_PageDown


MUIA_NList_ActiveObjectOnClick -- [ISG], BOOL

    Default FALSE. If set to TRUE, the NList object will become the MUIA_Window_ActiveObject 
    of its window when you click on it. In addition, the active selected entries 
    will switch an inactive color (e.g. grey) in case the NList object isn't currently active. 
    As soon as the object is active it will then also receive all user keys pressed. 


MUIA_NList_AdjustHeight -- [I..], BOOL

    Same function as List.mui/MUIA_List_AdjustHeight.

        Will adjust the nlist height if the nlist object is in a virtual
        group or if MUIA_NList_SourceInsert, MUIA_NList_SourceString,
        MUIA_NList_SourceArray or MUIA_List_SourceArray was used.

        When the object is in a virtual group, a re-layout of this one
        will be forced when the entries number of the NList object change,
        so all entries should always be visible.

    DEFAULT
        FALSE



MUIA_NList_AdjustWidth -- [I..], BOOL

    FUNCTION
        Same function as List.mui/MUIA_List_AdjustWidth.

        Will adjust the nlist width if the nlist object is in a virtual
        group or if MUIA_NList_SourceInsert, MUIA_NList_SourceString,
        MUIA_NList_SourceArray or MUIA_List_SourceArray was used.

    DEFAULT
        FALSE



NList.mcc/MUIA_NList_AutoClip

    NAME
        MUIA_NList_AutoClip -- [ISG], BOOL

    FUNCTION
        If set to TRUE and the NList object is in read-only (NoInput) mode and
        is set to select char-wide rather than by line, the selected content is
        immediately copied to the clipboard as soon as it is selected via the
        mouse.


MUIA_NList_AutoCopyToClip -- [IS.], BOOL

    FUNCTION
        If set to TRUE you can copy the selected area to the
        clipboard 0 with Amiga-C and Amiga-X (Amiga-X because
        i have seen that sometimes Amiga-C is a shortcut !).
        (works with both Right-Amiga and Left-Amiga keys)

        MUIA_NList_AutoCopyToClip == TRUE also requires that the NList object
        is either the window's active object (see MUIA_Window_ActiveObject) or
        the attached list object is window's default object (see
        MUIA_Window_DefaultObject). Otherwise nothing will ever be copied!



MUIA_NList_AutoVisible -- [ISG], BOOL

    FUNCTION
        Same function as List.mui/MUIA_List_AutoVisible.

        Seting this to TRUE, the NList object will automatically and
        always jump to show the active entry.

    DEFAULT
        FALSE



MUIA_NList_ButtonClick -- [..GN], LONG

    FUNCTION
        You'll get a notify on it each time the user
        clicks one of the buttons made by ESC O[...@<n>] or ESC o[...@<n>].

        The returned value is the <n> of the clicked image/object.
        (see MUIA_NList_DisplayHook for more).

        If you get that value later, it will still be <n> of the latest
        image/object clicked that you'll get.




MUIA_NList_ClickColumn -- [..G], LONG

    FUNCTION
        Same function as Listview.mui/MUIA_Listview_ClickColumn.



MUIA_NList_Columns -- [ISGN], BYTE *

    FUNCTION
        With this tag you can set/get the visible order of columns (as if changed
        by the user). It work for all columns in one time (use MUIM_NList_SetColumnCol
        if you want to exchange 2 columns).

        The value is a pointer on an BYTE array, each byte is for a column
        (in the visible order) and have the value of the display hook col
        which have to be displayed in it.

        The array must be ended with a -1 value.



MUIA_NList_CompareHook -- [IS.], struct Hook *

    FUNCTION
        Same function as List.mui/MUIA_List_CompareHook.



MUIA_NList_CompareHook2 -- [IS.], struct Hook *

    FUNCTION
        Same function as MUIA_NList_CompareHook but A2 will be the object
        and A1 a NList_CompareMessage struct pointer.



MUIA_NList_ConstructHook -- [IS.], struct Hook *

    FUNCTION
        Same function as List.mui/MUIA_List_ConstructHook.

        Think to finish lines entries on a \0 , \n and \r.
        The list will not display anything which come after
        a \n , \r or \0, so finish lines entries on a \0, \r
        and \n if you dont want to waste memory.

    SPECIAL INPUTS
        MUIV_NList_ConstructHook_String

        It's a builtin hook that copy a string entry.
        (so original string can be trash after)
        you must set MUIV_NList_DestructHook_String
        too if you use it.



MUIA_NList_ConstructHook2 -- [IS.], struct Hook *

    FUNCTION
        Same function as MUIA_NList_ConstructHook but A2 will be the object
        and A1 a NList_ConstructMessage struct pointer.



MUIA_NList_CopyColumnToClipHook -- [IS.], struct Hook *

    FUNCTION
        This hook will be called while a MUIM_NList_CopyToClip
        for each column string. You'll certainly get in entry
        a string given by your own MUIA_NList_DisplayHook/2, so
        you must not use the same buffer for both !

        You'll get the entry num in -1 element of the given array,
        elements 1 and 2 are the positions of the first selected
        char and the last+1.

        You must return the pointer of the string to copy to
        clipboard in element 0, a the string length in element 1.

        The builtin hook skip all ESC chars plus their next char
        (and [...] for ESC-P, ESC-I, ESC-O and ESC-o), and add a
        tab char between columns.



MUIA_NList_CopyColumnToClipHook2 -- [IS.], struct Hook *

    FUNCTION
        Same function as MUIA_NList_CopyColumnToClipHook but A2 will be the object
        and A1 a NList_CopyColumnToClipMessage struct pointer.



MUIA_NList_CopyEntryToClipHook -- [IS.], struct Hook *

    FUNCTION
        This work near like MUIA_NList_DisplayHook, execpt
        that it is not called when the NList object want to
        display its lines but when it want to copy them
        to clipboard (or other). See MUIM_NList_CopyToClip.

        You can return only one string pointer (only one
        column for copy), as element 0 of the array.

        The -1 element is the entry number only when
        you don't give a entry pointer to NList_CopyToClip method,
        else it's -1.

        Elements 1,2,3 and 4 of the given array are first column/pos
        and last column/pos which are selected.
        Elements 5 and 6 are 2, 1 or 0 when the 1th and 3rd pos are
        in the format preparse string, the special entry preparse string
        or in the normal string for that entry/columns.

        For column, -1 is the first and -2 the last, else it's its number.
        This is the number of displayed columns and not the corresponding
        entry in the array return by DisplayHook. Anyway, positions are
        calculated from strings returned by DisplayHook.

        For pos, -1 is left of column and -2 its end. The last pos should
        not be included.

        You should use MUIA_NList_CopyColumnToClipHook unless you don't
        want to be copied what is seen in the list.



MUIA_NList_CopyEntryToClipHook2 -- [IS.], struct Hook *

    FUNCTION
        Same function as MUIA_NList_CopyEntryToClipHook but A2 will be the object
        and A1 a NList_CopyEntryToClipMessage struct pointer.



MUIA_NList_DefaultObjectOnClick -- [ISG], BOOL

    FUNCTION
        If set to TRUE, the NList object will become the
        MUIA_Window_DefaultObject of its window when you
        click on it, so the user will be able to control
        the list with keys. The MUIA_Window_ActiveObject
        will be set to None, unless the current active
        object is the NList one itself or if it's the
        MUIA_NList_KeepActive one.

        There is a special meaning if you use both
        DefaultObjectOnClick and MUIA_NList_MakeActive.
        (see MUIA_NList_MakeActive)

    DEFAULT
        TRUE



MUIA_NList_DefClickColumn -- [ISG], LONG

    FUNCTION
        Same function as Listview.mui/MUIA_Listview_DefClickColumn.



MUIA_NList_DestructHook -- [IS.], struct Hook *

    FUNCTION
        Same function as List.mui/MUIA_List_DestructHook.

        MUIV_NList_DestructHook_String

        It's a builtin hook that free the string entry
        previously allocated and copied by
        the MUIV_NList_ConstructHook_String builtin hook.



MUIA_NList_DestructHook2 -- [IS.], struct Hook *

    FUNCTION
        Same function as MUIA_NList_DestructHook but A2 will be the object
        and A1 a NList_DestructMessage struct pointer.



MUIA_NList_DisplayHook -- [IS.], struct Hook *

    FUNCTION
        Same function as List.mui/MUIA_List_DisplayHook.

        Do not modify the buffers you return in the hook anywhere
        else than in the hook when called by NList.
        (if you do so you MUST set MUIA_NList_DisplayRecall)


        You should return the same thing if its called another
        time with the same inputs !
        The hook will be called with a pointer to the
        entry to be displayed in A1 and a pointer to
        a string array containing as many entries as
        your list may have cols in A2.
        You must fill this array with the strings that
        you want to display.
        The array is DISPLAY_ARRAY_MAX*2 large.
        In the DISPLAY_ARRAY_MAX+col element you can set a
        preparse string for the corresponding col element.
        Using it you'll be able to avoid copying the string in
        a buffer to add something in the beginning of the col
        string.

        The display hook also gets the position of the current entry
        as additional parameter. It is stored in the longword
        preceding the col array (don't forget it's a LONG).
        (setting that LONG value to -2 is another way to tell the object
        to not consider the return string pointeur as valid next time
        he will want to use it, and he will recall the hook).

        When the hook function will be called to get the title strings,
        you'll get NULL in A1, and -1 as position of current entry.


        The hook function will be called each time a line (or a part of
        it) need to be drawn (and when NList need to compute lenght of
        columns contents).


        Here are the escape sequence known by the parsing of NList :
              (If you use C, ESC b can be written "\033b")

        \t          Tabulation. Go to the next tab boundary of the col.
                    tab positions are separated by 8 spaces by default.
        ESC -       Disable text engine, following chars will be printed
                    without further parsing.
        ESC u       Set the soft style to underline.
        ESC b       Set the soft style to bold.
        ESC i       Set the soft style to italic.
        ESC n       Set the soft style back to normal.
        ESC <n>     Use pen number n (2..9) as front pen. n must be a valid
                    DrawInfo pen as specified in "intuition/screens.h".
        ESC c       Center current line. only valid at the beginning.
        ESC r       Right justify current line. only valid at the beginning.
        ESC l       Left justify current line. only valid at the beginning.

        These ones are new or modified :

        ESC j       Justify left and right current line. only at beginning.
        ESC I[<s>]  Draw MUI image with specification <s>.
                    See Image.mui/MUIA_Image_Spec for image spec definition.
        ESC O[<p>]                     (ESC O[<s>|<width>|<height>,<minwidth>])
                    Draw the MUIM_NList_CreateImage at adress <p>.
                    (<p> should be an 8 hex digits number).
        ESC o[<n>]                     (ESC o[<s>|<width>|<height>,<minwidth>])
                    Draw the MUIM_NList_UseImage number <n>. If the <n> UseImage
                    don't exist or has been set to NULL, no image is drawn.
        ESC P[]     Use default front pen.
        ESC P[<n>]  Use pen number <n>. (it's a direct pen number, so you must
                    make MUI_ObtainPen and MUI_ReleasePen for it yourself,
                    best to do it is in Setup() and Cleanup() of a subclass).
        ESC T       Draw horizontal line on top of the entry for the col.
        ESC C       Draw horizontal line centered in the entry for the col.
        ESC B       Draw horizontal line on bottom of the entry for the col.
        ESC E       Draw horizontal line centered in the entry for the col,
                    but only on the left and right of the line contents.
        ESC t , ESC t[<n>] , ESC t[M<n>] , ESC t[I<n>]
                    Make the ESC C and ESC E horizontal line become thick and filled
                    with some color :
                    default is MPEN_FILL.
                    [<n>]  means than <n> is a direct pen color, like for ESC P[<n>]
                    [M<n>] means that <n> is MUI pen color number (MPEN_xxx ie 0..8)
                    [I<n>] means that <n> is Intuition dri pen number 0..11 (see
                            "intuition/screens.h")
        ESC t[N], ESC t[N<n>], ESC t[NM<n>], ESC t[NI<n>]
                    Make the ESC T, ESC C,ESC B, ESC E become a single black line,
                    or not black when using a <n>, M<n> or I<n> pen color.
                    ('N' is for Not thick ;)

        with ESC O[] and ESC o[], you can add [...@<n>] which will make the image/object
        act as a relverify button. When this "button" is released NList will notify
        MUIA_NList_ButtonClick with the value <n>.

        with ESC I[], ESC O[] and ESC o[], you can add [...|<width>] or
        [...|<width>|<height>] or [...|<width>|<height>,<minwidth>] or
        [...,<minwidth>] where :
          <width> will be the width in pixels of the image/object.
                  -1  means default image width unless <minwidth> is set.
                   0  means default image width.
          <height> will be the height in pixels of the image/object.
                  -1  means default image height (entry height is max).
                   0  means entry height.
          <minwidth> will be the min width in pixels before the next char/string/image.
                  when present, default height become entry height and
                  width become minwidth (if minwdith is bigger than image default
                  width), unless you set <width> and/or <height>.
          <minwidth> <width> and <height> must be a decimal number (%ld).



MUIA_NList_DisplayHook2 -- [IS.], struct Hook *

    FUNCTION
        Same function as MUIA_NList_DisplayHook but A2 will be the object
        and A1 a NList_DisplayMessage struct pointer.



MUIA_NList_DisplayRecall -- [.S.], BOOL

    FUNCTION
        If for some unusual reason you modify one of the buffer that
        your DisplayHook function usually return anywhere else than
        in the DisplayHook function when called by the NList object,
        you must set it to TRUE, so the object will know it.



MUIA_NList_DoubleClick -- [..GN], LONG

    FUNCTION
        You'll get a notify on it each time the user double
        clicks on an entry in the list, or on the title.

        The value is the entry number, which will be -1 when
        it's the title.

        You'll get a notify on it too when you press the 'return' key
        and the NList object is active or default.

        If you get() it, you'll get the last click position, which
        can be -2 if it was on nothing (ie not entry or title).

        For triple clicks and more, use MUIA_NList_MultiClick.

    NOTE
        Disabled for the title when MUIA_NList_TitleClick is used.



MUIA_NList_DragColOnly -- [ISG], LONG

    FUNCTION
        When set to a col number (displayhook col number, not the visible
        one), only the text of that col for the selected entry will
        be dragged instead of the visible part of the entry.

        Set it to -1 to come back to standard/default mode when you have
        changed it !


MUIA_NList_DragSortable -- [ISG], BOOL

    FUNCTION
        Same function as List.mui/MUIA_List_DragSortable.

        DragType will be MUIV_NList_DragType_Default unless you set it.

        No need for you to set MUIA_Dropable or MUIA_Draggable.

    DEFAULT
        FALSE


MUIA_NList_DragSortInsert -- [..GN], BOOL

    FUNCTION
        Same as MUIA_NList_InsertPosition but the notify is made only after
        a MUIA_NList_DragSortable move.

        MUIV_NList_DragType_Borders     drag on borders and with qualifier.
        MUIV_NList_DragType_Qualifier   drag only using qualifier.

    FUNCTION
        Same function as Listview.mui/MUIA_Listview_DragType.

        If you want the user to be able to drag items out of
        your list, you must set this.
        Don't use MUIA_Draggable with NList or NListview.



MUIA_NList_DropMark -- [..G], LONG

    FUNCTION
        Same function as List.mui/MUIA_List_DropMark.

        After a successfull drop operation, this attribute holds
        the position where we should insert the new entry(ies).



MUIA_NList_DropType -- [..G], LONG

    FUNCTION
        Same function as MUIA_NList_DropMark but will return the
        current DropMark type instead of the DropMark entry number.

        After a successfull drop operation, this attribute holds
        the type of dropmark which where drawn.



MUIA_NList_Entries -- [..GN], LONG

    FUNCTION
        Same function as List.mui/MUIA_List_Entries.



MUIA_NList_EntryClick -- [..GN], LONG

    FUNCTION
        You'll get a notify on it each time the user click
        on an entry in the list (on the title, use
        MUIA_NList_TitleClick for that).

        The value is the entry number.

        You'll get a notify on it too when you press the 'return' key
        and the NList object is active or default, but only if there
        is no notify asked on MUIA_NList_DoubleClick.

        If you get() it, you'll get the last click position, which
        can be -1 when on title and -2 if it was on nothing.




MUIA_NList_EntryValueDependent -- [ISG], BOOL

    FUNCTION
        If your display hook return different strings when the
        entry num value change for a identical entry pointer
        then you should set it.

    DEFAULT
        FALSE



MUIA_NList_Exports -- [ISG], LONG

    FUNCTION
        Tell the NList object what parts of it's state will have to
        be saved in MUIM_Export method (which is called by the
        MUIM_Application_Save method if the object has a ObjectID).

    SPECIAL INPUTS
        MUIV_NList_Exports_Active       save active entry number.
        MUIV_NList_Exports_Selected     save selected entries numbers.

        MUIV_NList_Exports_All

    NOTE
        MUIV_NList_Exports_Selected can make a very long export (so a big program
        .cfg file) if the list has many selected entries. It take one long int
        (ie 4 bytes) for each selected entry...

        Active and First are always exported by the MUIM_Export method,
        having MUIV_NList_Exports_Active and MUIV_NList_Exports_First set or not.

    DEFAULT
        (MUIV_NList_Exports_Active | MUIV_NList_Exports_First | MUIV_NList_Exports_Cols)

        in all the selected area. Else the color is forced only at the
        beginning of the area and can be changed by text escape sequences.

        The default is set by the user in the pref .mcp class.

        Getting in will give its current value.


MUIA_NList_Format -- [ISG], STRPTR

    FUNCTION
        NList is able to handle multi column lists. To define
        how many columns should be displayed and how they
        should be formatted, you specify a format string.

        This format string must contain one entry for each column
        you want to see. Entries are seperated by commas, one
        entry is parsed via dos.library/ReadArgs().

        The template for a single entry looks like this:

        DELTA=D/N,PREPARSE=P/K,COL=C/N,BAR/S,TBAR/S,NOBAR=NB/S,
        SIMPLEBAR=SBAR/S,NOTITLEBUTTON=NOTB/S,
        WEIGHT=W/N,MINWIDTH=MIW/N,MAXWIDTH=MAW/N,
        COLWIDTH=CW/N,MINCOLWIDTH=MICW/N,MAXCOLWIDTH=MACW/N,
        PIXWIDTH=PW/N,MINPIXWIDTH=MIPW/N,MAXPIXWIDTH=MAPW/N,
        PARTCOLSUBST=PCS/K

    First ones are like (or nearly) MUIA_List_Format ones :

        DELTA
           Space in pixel between this column and the next.
           the last displayed column ignores this setting.
           Defaults to 4.

        PREPARSE
           A preparse string for this column.

        COL
           This value adjusts the col number of the current column.
           Defaults to current column number (0,1,...)
           You can't use identical COL values for 2 or more columns.

        BAR
           Will draw a vertical bar between this and the next column.

        WEIGHT
           The weight of the column. As for MUI's group.

        MINWIDTH
           Minimum percentage of the list width for the current column.

        MAXWIDTH
           Maximum percentage of the list width for the current column.

        TBAR
           Will draw a vertical bar between this and the next column
           but only in the title (ignored if BAR is set).
           THIS IS A DEFAULT !

        NOBAR
           Don't draw a vertical bar between this and the next column at all.

        SIMPLEBAR
           Make te vertical bar a simple black one.

        NOTITLEBUTTON
           Will prevent the title of the column to act as a relverify
           button when you set MUIA_NList_TitleClick (or make a notify
           on it).

        COLWIDTH
           Wanted number of chars for the current column.
           You will get as PIXWIDTH with number*font_with.
           Possibly more than number chars will fit in the
           column if you use proportional font, anyway you
           are sure than number non italic chars will fit.

        MINCOLWIDTH
           Minimum number of chars for the current column.

        MAXCOLWIDTH
           Maximum number of chars for the current column.

        PIXWIDTH
           Wanted number of chars for the current column.

        MINPIXWIDTH
           Minimum number of chars for the current column.

        MAXPIXWIDTH
           Maximum number of chars for the current column.

        PARTCOLSUBST
           If the partial column feature is turned on by the
           user (in his configuration) and the application
           developer has specified this option for a particular
           column, then a "..." text is displayed at the
           defined position if not all text fits into the
           column rather than showing a dotted vertical line
           at the end of the column. Possible values for
           this option are:

              DISABLED
                explicitly disables this feature for this
                column

              LEFT
                put "..." on the left side and strip text
                left aligned.

              CENTER
                put "..." at the center of the column and
                strip text on both sides around it.

              RIGHT
                put "..." on the right side and strip text
                right aligned.


        Note: You will have as many columns in your list as
              entries in the format string (i.e. number of
              commas + 1). Empty entries, e.g. with a format
              string of ",,,," are perfectly ok.

        MINPIXWIDTH, MAXPIXWIDTH, MINCOLWIDTH, MAXCOLWIDTH,
        MINWIDTH and MAXWIDTH will not be used if PIXWIDTH,
        or COLWIDTH is used.

        Only one of PIXWIDTH, COLWIDTH and WEIGHT will be
        used, the first find in this order.
        Biggest of MINPIXWIDTH, MINCOLWIDTH and MINWIDTH.
        Smallest of MAXPIXWIDTH, MAXCOLWIDTH and MAXWIDTH.
        If the min is bigger than the max the min will be used.

        You should used PIX ones only for columns with images,
        and COL ones when you want to be sure to get as many
        chars you want.

        All chars/images will be drawn for the last column
        always, you should specify some width for it anyway
        as it will be used for centered and right aligned texts !

        Default values : WEIGHT=-1, MINWIDTH=5, MAXWIDTH=10000.

        Use MINWIDTH=0 if you don't use PIXWIDTH or COLWIDTH and
        don't want any min value.

        If you want to use WEIGHT values as percentage of the list
        width, just choose them to have their total being 100.

        WEIGHT = -1 mean that you want the column to have
        the width of the largest entry's column contents.
        MINWIDTH = -1 have the same meaning as for WEIGHT but for
        the min value.
        Default will be 100 for the last column, set it to -1 or
        -2 if you want to force it when more than one column, and
        to -2 to force it when only one column.

        Be aware that it can take long time to do that when there
        are many entries since this need a call to the dislpayhook,
        parse and find real length of all entries.
        Anyway using such stuff for one or more column has the
        same overhead.

        The default list format is an empty string (""), this
        means a one column list without special formatting.

    NOTE
        Actually MUIA_NList_Format will not try to see if the new
        format is similar to previous one. It means that all
        column width will be re-computed (and all entries parsed
        if WEIGHT or MINWIDTH is -1), same for wrapping
        which will be recomputed for all entries.
        So, it's better to do it before inserting entries
        if you want to do both.
        If you want to clear, insert, and set the format, the
        best is to set the format after the clear (fastest, no
        entry to parse) and before the insert.

    BUGS (FEATURE)
        Currently there is a maximum of 64 columns for a list.

MUIA_NList_IgnoreSpecialChars -- [ISG], const char *

    FUNCTION
        Used to let NList ignore a list of user definable characters during
        string parsing. Some greek fonts need the 0xA0 character to display
        an Alpha characters. In this case the string "\xa0" should be supplied
        to make NList ignore this character and not treat 0xA0 as a "non
        breaking space".
        This string will *NOT* be copied by NList and must remain valid as long
        as the object exists!

    DEFAULT
        NULL




MUIA_NList_Imports -- [ISG], LONG

    FUNCTION
        Tell the NList object what parts of it's state must be loaded
        (and used) in MUIM_Import method (which is called by the
        MUIM_Application_Load method if the object has a ObjectID).

    SPECIAL INPUTS
        MUIV_NList_Imports_Active     load previous active entry number (and make it active).

MUIA_NList_InsertPosition -- [..GN], LONG

    FUNCTION
        Same function as List.mui/MUIA_List_InsertPosition.



MUIA_NList_KeepActive -- [.S.], Obj *

    FUNCTION
        Usefull when MUIA_NList_DefaultObjectOnClick if you
        don't want the specified object to be desactivated.
        A NListview object set it to it's NList child at
        creation time, so you should not have to use that tag.



MUIA_NList_KeyUpFocus -- [ISG], Object *

    FUNCTION
        Allows to specify a specific object that will be set as the new
        window's active object in case the user pressed the UP cursor key
        and the NList object itself doesn't have anything further to
        scroll up.



MUIA_NList_KeyDownFocus -- [ISG], Object *

    FUNCTION
        Allows to specify a specific object that will be set as the new
        window's active object in case the user pressed the DOWN cursor key
        and the NList object itself doesn't have anything further to
        scroll down.



MUIA_NList_KeyLeftFocus -- [ISG], Object *

    FUNCTION
        Allows to specify a specific object that will be set as the new
        window's active object in case the user pressed the LEFT cursor key
        and the NList object itself doesn't have anything further to
        scroll to the left.



MUIA_NList_KeyRightFocus -- [ISG], Object *

    FUNCTION
        Allows to specify a specific object that will be set as the new
        window's active object in case the user pressed the RIGHT cursor key
        and the NList object itself doesn't have anything further to
        scroll to the right.



MUIA_NList_LineHeight -- [..GN], LONG

    FUNCTION
        Get the current line height.



MUIA_NList_MakeActive -- [.S.], Obj *

    FUNCTION
        Use it if you want an object to be activated when you click
        in the list object.
        If you want to be able to control the list with key, you
        should use MUIA_NList_DefaultObjectOnClick instead.

        If you use both MUIA_NList_MakeActive and
        MUIA_NList_DefaultObjectOnClick then the specified object
        will be activated only if there is already an active one.

        The only object which should be set should be the NListview
        parent object of the current NList one.



MUIA_NList_MinColSortable -- [ISG], LONG

    FUNCTION
        Sets the number of the first visible column which
        can be sorted, ie exchanged with some other one.

        Default is 1, making the leftmost (0) column not sortable.

        Just set it to a big number (100 for example) to forbid
        the columns sorting.


MUIA_NList_MinLineHeight -- [IS.], LONG

    FUNCTION
        Same function as List.mui/MUIA_List_MinLineHeight.

        Sets the minimum line height for lists in pixels.

        If <= 0 then it's absolute value will replace the
        'Leading' value of prefs which is added to the
        font height.

        It seems that original MUIA_List_MinLineHeight use
        its positive value as a 'leading' one, which is not
        logical when i read its doc (!), so i do the
        change internally to get it works like with list...


MUIA_NList_MultiClick -- [..GN], LONG

    FUNCTION
        You'll get a notify on it each time the user
        multiclicks more than 2 times on an entry in the
        list, or on the title. You'll get the number of
        the click (3, 4, 5...) for each. Note that you'll
        not get MUIA_NList_MultiClick for a double click;
        you must use MUIA_NList_DoubleClick for that.
        The time between each click must be less or equal
        to the double click time set in Amiga Input prefs.

        You can know on which entry the multiclick was made
        getting MUIA_NList_DoubleClick value.

        So you can make a notification on it.

    NOTE
        Disabled for the title when MUIA_NList_TitleClick is used.



MUIA_NList_MultiClickAlone -- [..GN], LONG

    FUNCTION
        You'll get a notify only for the final multiclick number,
        so if there are 3 clicks there will be only one multiclickalone
        notified, a little (max time between 2 clicks) after the 3rd one.
        It is the major change with classic MUIA_NList_DoubleClick and
        MUIA_NList_MultiClick which do the notify for all clicks.

        The drawback is the unavoidable delay between the last click
        and the notify.

        You can know on which entry the multiclickalone was made
        getting MUIA_NList_DoubleClick value.

        You can make a notification on it.

MUIA_NList_Quiet -- [.S.], BOOL

    FUNCTION
        Same function as List.mui/MUIA_List_Quiet.

        Think about using it when you insert/remove several entries
        one by one, it will go much faster.
        In all cases all changes which can be done later are delayed.
        Quiet_Full mean that no notify caused by changes in the list will
        be made, while Quiet_Visual will done them (but delayed to after
        the Quiet_None).

    SPECIAL INPUTS
        MUIV_NList_Quiet_None       same as FALSE.

MUIA_NList_SourceArray -- [I..], APTR

    FUNCTION
        Same function as List.mui/MUIA_List_SourceArray.



MUIA_NList_SourceInsert -- [I..], struct MUIP_NList_InsertWrap *

    FUNCTION
        Same as DoMethod(obj,MUIM_NList_InsertWrap,...)
        with ... same as the contents of the passed struct,
        but at init.




MUIA_NList_SourceString -- [I..], char *

    FUNCTION
        Same as
        DoMethod(obj,MUIM_List_Insert,string,-2,MUIV_NList_Insert_Bottom)

        Default is 8.


MUIA_NList_Title -- [ISG], char *

    FUNCTION
        Same function as List.mui/MUIA_List_Title.

        The title will be redraw each time you set it.

        When you use a display hook, its value is used as a BOOL/LONG
        which can have any value (just not NULL if you want to see it).

        The value returned by get() will be the same than the last one
        given in the set() or at init.



MUIA_NList_TitleClick -- [ISGN], LONG

    FUNCTION
        You'll get a notify on it each time the user
        clicks one the title (only if on a column, so not on the
        vertical bar column separator which is used to modify the
        column width with mouse).

        The returned value is the col number (display hook col number).

        If you get that value later, it will still be the latest
        *title* click col that you'll get.

        If you ask for a notify on that tag, or if you set it (with any
        value) the title will act as if each of its column titles were
        separated buttons, notifying that tag when there are released.

        The (released) look for those title "buttons" will be better
        if you use MUIA_NList_TitleSeparator and BAR or TBAR for each
        column in the MUIA_NList_Format string.

        There is no shortkeys for these custom buttons and never be,
        so think to give another way to access the related stuffs.

        Don't ask for customized frames for them :  there are not real
        MUI and separated buttons but directly handled by NList, and i
        found it nice as is.

    NOTE
        When you use MUIA_NList_TitleClick, you'll not receive
        MUIA_NList_DoubleClick and MUIA_NList_MultiClick when clicking
        on the title any more.

    EXAMPLES
        See NList-Demo program.

        MUIM_NList_Sort3, this one called from a MUIA_NList_TitleClick/2 notify).

    SPECIAL INPUTS
        MUIV_NList_TitleMark2_None
        MUIV_NList_TitleMark2_Down   | col

    FUNCTION
        Setting this tag you can choose between the classic
        list selection by line, or using a char precision
        selection.

        This should be used only for textviewer like stuff,
        and never for standard lists.
        Anyway its the only way to make direct copytoclip
        of a part of a line...

        Default is MUIV_NList_TypeSelect_Line of course.

        it'll call MUIA_NList_CompareHook or MUIA_NList_CompareHook2 hook
        in that case.

        When you are overriding this method you probably  would  like  to
        override     MUIM_NList_Construct,     MUIM_NList_Destruct    and
        MUIM_NList_Display method as well.

MUIM_NList_Construct --

        SYNOPSIS
        DoMethod(obj,MUIM_NList_Construct,APTR entry,APTR pool);

    FUNCTION
        This method is called  ONLY  by  NList.mcc  when  application  is
        creating     new     entry     f.e.    when    MUIM_NList_Insert,
        MUIM_NList_InsertSingle or MUIM_NList_Replace is called. So, this
        method  is only useful within NList.mcc subclass, function method
        should   looks   like    normal    MUIA_NList_ConstructHook    or
        MUIA_NList_ConstructHook2  hook  function.  If your subclass will
        not override this method NList.mcc implementation will  be  used,
        and       it'll       call       MUIA_NList_ContructHook       or
                MUIA_NList_ConstructHook2 hook in that case.

        When you are overriding this method you probably  would  like  to
        override      MUIM_NList_Destruct,     MUIM_NList_Compare     and
        MUIM_NList_Display method as well.

        INPUTS
        entry - original entry pointer passed to  f.e.  MUIM_NList_Insert
                                method. Equivalent of A1 register of
                MUIA_NList_ConstructHook.

                pool  - pool  header  pointer.  Equivalent  of  A2  register  of
                MUIA_NList_ConstructHook.

    RESULT
                New entry, similar as returned by one of construct hooks.

        NOTE
        Do not even think about calling it by yourself! Method parameters
        structure might grow in the future! Be warned.

        Internal implementation of this method can use internal or passed
        arguments,  so  please  do  not  cheating  and  if  you  are  not
                overriding it, pass the original arguments to super class.



MUIM_NList_ContextMenuBuild --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_ContextMenuBuild, LONG mx, LONG my, LONG pos,
                                                LONG column, LONG flags,LONG ontop);

    FUNCTION
        Give possibilities to use MUIM_ContextMenuBuild builtin in NList
        and a custom context menu for a NList subclass.

        Here is how NList MUIM_ContextMenuBuild work :

        If MUIA_ContextMenu is NULL, NULL is returned (no menu).

        If MUIA_ContextMenu is none of special values, the supermethod is called.

        If MUIA_ContextMenu is MUIV_NList_ContextMenu_Never, MUIA_ContextMenu is
        set to NULL and NULL is returned.

        Else (it's a special value) MUIM_NList_ContextMenuBuild is called :

          If MUIM_NList_ContextMenuBuild return -1, NULL will be returned (no menu).

          If MUIM_NList_ContextMenuBuild return NULL, NList will return its own
          context menu, depending on prefs (it's the default case).

          If MUIM_NList_ContextMenuBuild return an menu object, NList will
          enable/disable its own menu entries in the menu if it found some,
          then return thqt object.

          2 special menuitems are reconized by NList, and are found by :
            DoMethod(MenuObj,MUIM_FindUData,MUIV_NList_Menu_Default_This)
          and
            DoMethod(MenuObj,MUIM_FindUData,MUIV_NList_Menu_Default_All)



        MUIA_ContextMenu special values are actuallly used :

          MUIV_NList_ContextMenu_Default   replaced by one of followings.
          MUIV_NList_ContextMenu_TopOnly   only on title/top of list.
          MUIV_NList_ContextMenu_Always    always.
          MUIV_NList_ContextMenu_Never     never, repaced by NULL after.

          when using MUIV_NList_ContextMenu_TopOnly NList will set MUIA_ContextMenu
          NULL/non-NULL when the mouse move, which should permit to have
          the window menu avaible when the contents menu is not visible.

          Anyway actually (MUI 3.8) MUI has a bug/feature which make the
          MUIA_ContextMenu being looked at only when the mouse *enter*
          within the object bounds. MUIV_NList_ContextMenu_TopOnly stuff
          will be nicer when that MUI problem is fixed...

        Of course if you want NList to do what has to be done when a menu item
        has been selected, your MUIM_ContextMenuChoice should call the supermethod.

    INPUTS (for MUIM_NList_ContextMenuBuild)

        mx      current mouse x.
        my      current mouse y.
        pos     entry number returned by NList_TestPos.
        column  column returned by NList_TestPos.
        flags   flags returned by NList_TestPos.
        ontop   TRUE if mouse is on title/top of the list.

    RESULT
        NULL, -1 or a menustrip object.

    EXAMPLES
        To make a ContextMenu but have the NList one appear when the
        mouse in on title/top, just set MUIA_ContextMenu,MUIV_NList_ContextMenu_Always
        and make MUIM_NList_ContextMenuBuild return NULL when ontop in TRUE (else
        return your menustrip object). Call MUIM_ContextMenuChoice supermethod too.

        To make your own context menu which have the same menuitems as ones
        in NList context menu, set MUIA_ContextMenu,MUIV_NList_ContextMenu_Always
        and make MUIM_NList_ContextMenuBuild return always your menustrip object.
        Make 4 menuitems in your menustrip object which will be like these :
        { NM_ITEM ,  "Default Width: this" , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefWidth_This },
        { NM_ITEM ,  "Default Width: all"  , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefWidth_All },
        { NM_ITEM ,  "Default Order: this" , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefOrder_This },
        { NM_ITEM ,  "Default Order: all"  , 0 ,0 ,0 ,(APTR) MUIV_NList_Menu_DefOrder_All },
        They will be automatically enabled/disabled as needed by NList  :)
        Call MUIM_ContextMenuChoice supermethod too.


MUIM_NList_CopyTo --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_CopyTo, LONG pos, char *filename,
                                        APTR *result, APTR *entries);

    FUNCTION
        Do a copy to clipboard from some list entries or strings.

    INPUTS
        pos      entry number to be copied.
                 if MUIA_NList_CopyToClipHook is specified, it's what
                 it will return which will be copied instead of just
                 using the entry pointer as a string pointer.

                 special values :

            MUIV_NList_CopyTo_Active    copy list active entry
            MUIV_NList_CopyTo_Selected  copy list selected entries
            MUIV_NList_CopyTo_All       copy all list entries
            MUIV_NList_CopyTo_Entries   copy specified entries
            MUIV_NList_CopyTo_Entry     copy specified entry

            a "\n" will be insert after each entry contents.

        filename name of the file to copy to. If NULL then the copy will be
                 done to a string (strptr).
        result   LONG pointer which fill be filled with MUIV_NLCT_Success if
                 no error occured while opening and writing in the file, else
                 it will be filled with MUIV_NLCT_OpenErr, MUIV_NLCT_WriteErr
                 or MUIV_NLCT_Failed (failed somewhere when making copy data).

                 if filename is NULL, result will be filled with a string pointer
                 to a string allocated by AllocVec(). Datas will have been copied
                 in that string. YOU'LL HAVE TO FREE TAHT string pointer YOURSELF,
                 with a FreeVec(). If the returned string pointer is NULL then
                 the copy failed.
        entries  pointer to some entry, string, entries array or string array.
                 Its use depend on the pos value :
                 if MUIV_NList_CopyTo_Entry   then it's an entry pointer.
                 if MUIV_NList_CopyTo_Entries then it's an entry pointer
                                              array NULL terminated.
                 else :  not used, set to NULL.

    EXAMPLES
        LONG result = 0;
        DoMethod(obj,MUIM_NList_CopyTo, 5, "RAM:test.txt", &result, NULL, NULL);

          will copy the 5th entry to file RAM:test.txt, using
          MUIA_NList_CopyToClipHook if set.


        LONG result = 0;
        DoMethod(obj,MUIM_NList_CopyTo, MUIV_NList_CopyToClip_Selected,
                                            "PRT:", &result, NULL, NULL);
          will copy all selected entries to printer, using
          MUIA_NList_CopyToClipHook for each if set.


        char *strptr = NULL;
        DoMethod(obj,MUIM_NList_CopyTo, MUIV_NList_CopyTo_All,
                                            NULL, &strptr, NULL, NULL);
          will copy all list entries to the string returned in strptr.
          you must make a FreeVec(strptr) by yourself after.

    FUNCTION
        Do a copy to clipboard from some list entries or strings.

    INPUTS
        pos      entry number to be copied.
                 if MUIA_NList_CopyToClipHook is specified, it's what

                 if MUIV_NList_CopyToClip_Strings then it's an string pointer
                                                  array NULL terminated.
                 else :  not used, set to NULL.
        hook     hook function which will be used (if not NULL) for
                 MUIV_NList_CopyToClip_Strings and
                 MUIV_NList_CopyToClip_String
                 instead of MUIA_NList_CopyToClipHook
                 Should be NULL most of time.

    EXAMPLES
        DoMethod(obj,MUIM_NList_CopyToClip, 5, 0, NULL, NULL);
          will copy the 5th entry to clipboard 0, using
          MUIA_NList_CopyToClipHook if set.

                                            0, NULL, NULL);
          will copy all selected entries to clipboard 0, using
          MUIA_NList_CopyToClipHook for each if set.

        DoMethod(obj,MUIM_NList_CopyToClip, MUIV_NList_CopyToClip_String,
                                            0, "my string", NULL);
          will copy "my string" to clipboard 0.

    NOTE
        MUIV_NList_CopyToClip_Strings and MUIV_NList_CopyToClip_String
        are here to permit simple text copy to clipboard for non nlist
        object related stuff (anyway a NList object must be here to use
        them...). They can use their own hook instead of nlist one if
        non NULL, anyway look at MUIA_NList_CopyToClipHook to see how
        this hook will be used.



MUIM_NList_CreateImage --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_CreateImage,Object *imgobj, ULONG flags);

    FUNCTION
        Same function as List.mui/MUIM_List_CreateImage.

        Any transparent color in the source Bitmap/Bodychunk
        object will work (except if flags is ~0L).

        You must use MUIM_NList_CreateImage in Setup() or after
        and MUIM_NList_DeleteImage in Cleanup() or before,
        because the mri of the NList object must be valid.
        Setup() and Cleanup() are the best because MUI_ObtainPen()
        and MUI_ReleasePen() are used, and then pens will be
        released while iconification and will be re-obtained
        if the screen change.

        Take a look at MUIM_NList_UseImage which is far easier to
        use.

        Standard flags value is 0.

        If flags is ~0L then FillArea will not be set to FALSE on the object
        (for any other value, FillArea is set to FALSE)

        If flags is ~0L for a Bitmap/Bodychunk then it will be really the
        given object which will be drawn, as for non Bitmap/Bodychunk objects.


        The imgobj can (nearly) be any object, but take care of that :

        - the object should not test and use user inputs, the object
          should just be able to draw itself within the _left(obj),
          _top(obj), _width(obj) and height(obj) it will have when its
          Draw method is called.
        - the object class MUST NOT be Group or subclass of it.
        - the given imgobj must not be attached to any group object
          anywhere else, because a ADDMEMBER will be done with it.
        - Each imgobj can be used with one and only one NList object.
        - you can use the return pointer with ESC O[<ptr>] and ESC o[<num>].
        - the object will receive two tags just before its Draw method will
          be called : set(imgobj,MUIA_NLIMG_EntryCurrent,current_entry_number) and
          set(imgobj,MUIA_NLIMG_EntryHeight,height_of_each_entry_of_the_list)
          which are usefull in some case to draw things (see demo example).
        - a new stuff is to use it with ESC O[<ptr>;<tag>;<value>], in that case
          a set(imgobj,tag,value) will be done just before drawing it, so
          you can make an object which will draw different things when that tag
          value is changed. Setting this tag MUST NOT make the object being
          redrawn !!!
          <tag> and <value> must both be in hexadecimal (%lx).
        - if you use ;<tag>;<value> in one ESC sequence for an imgobj, you should
          use it everywhere you use that imgobj because there is no default for it.
        - The imgobj height will always be set to the entries height.
        - The mindefheight of imgobj will become the min height for entries.
        - Think it's still a new testing stuff...

        Note:
          Previously the object was disposed by NList at its end, actually a call
          to MUIM_NList_DeleteImage will REMMEMBER it, and so you have to dispose
          it yourself after !

        Look the demo program to see a way to use it...


    RESULT
        The result you get is a struct BitMapImage pointer which
        will exist between the MUIM_NList_CreateImage and
        MUIM_NList_DeleteImage, with a valid bitmap, width and
        height for the current screen.

        If you use it for a non Bitmap/Bodychunk object (or with flags
        set to ~0L) then the mask and imgbmp fields of the returned
        struct BitMapImage are not valid, and obtainpens is a pointer to
        the object.

        The only thing you should do with it is to include it in
        \33O[%08lx]. The result may be NULL in which case NList
        was unable to create the image, but the \33O[] combination
        simply draws nothing when receiving a NULL.

        ATTENTION:
        The returned pointer doesn't give the same structure than
        MUIM_List_CreateImage (in standard List class) would do :
        both are not compatible at all !



MUIM_NList_DeleteImage --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_DeleteImage,APTR listimg);

    FUNCTION
        Same function as List.mui/MUIM_List_DeleteImage.

        MUIA_NList_DestructHook  or MUIA_NList_DestructHook2 hook in that
        case.

        When  you  are  overriding  this   method   you   must   override
        MUIM_NList_Construct    and   probably   MUIM_NList_Compare   and
        MUIM_NList_Display method as well.

    INPUTS
                entry - entry pointer returned by MUIM_NList_Construct method.

                pool  - pool header pointer.

    RESULT
        Currently undefined. If you are overriding it completely,  please
        return 0, if not use the value returned by super class!

        NOTE
        Do not even think about calling it by yourself! Method parameters
        structure might grow in the future! Be warned.

        Internal implementation of this method can use internal or passed
        arguments,  so  please  do  not  cheating  and  if  you  are  not
                overriding it, pass the original arguments to super class.

MUIM_NList_DoMethod --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_DoMethod,LONG pos,
                      APTR DestObj,ULONG FollowParams,ULONG method,...);

    FUNCTION
        The given method will be executed for each selected entry, the
        active entry, all entries, or one specified entry of the NList
        object.

        Each DoMethod() can be done on the NList object, its _app object,
        a specified object, or the entry pointer if (and only if) it's
        an object.

        Following arguments can be automatically adjusted for each call
        using special values, like in the MUIM_Notify method (you must
        specified the numer of following argument too, as there will be
        copied in a temporary buffer - alloced in the stack).

    INPUTS
        pos -           the entry number for which you want to do the method.

          special values :
          MUIV_NList_DoMethod_Active    do it for the active entry.
          MUIV_NList_DoMethod_Selected  do it for all selected entries.
          MUIV_NList_DoMethod_All       do it

        DestObj -       the object on which the method will be done.

          special values :
          MUIV_NList_DoMethod_Entry     use entry pointer as target object for method.
          MUIV_NList_DoMethod_Self      use the NList object as target for method.
          MUIV_NList_DoMethod_App       use the _app(NList object) as target for method.

        FollowParams -  the number of following parameters (including "method").
                        (maximum 40 to prevent errors and stack overflow)

        method -        the method which will be done.

        ... -           the method parameters.

          special values :
          MUIV_NList_EntryValue         replaced by the "current" entry pointer.
          MUIV_NList_EntryPosValue      replaced by the "current" entry number.
          MUIV_NList_SelfValue          replaced by the NList object.
          MUIV_NList_AppValue           replaced by _app(NList object)

    NOTES
        Don't use this to do things on the NList object when a specific way
        to do it exists (don't use it to remove entries in the nlist object
        itself for example).

        When using it in a notification, MUIV_TriggerValue and MUIV_TriggerValue
        special values will be replaced by the notify superclass as usual.

    EXAMPLES
        Insert all entries from nlist L1 to nlist L2 :

        DoMethod(L1, MUIM_NList_DoMethod, MUIV_NList_DoMethod_All,
          L2, 3,
          MUIM_NList_InsertSingle, MUIV_NList_EntryValue, MUIV_NList_Insert_Bottom);

        (it would be better to make set(L2,MUIA_NList_Quiet,TRUE) before and
         set(L2,MUIA_NList_Quiet,FALSE) after when there are many entries...)


        If the entries of nlist L1 are objects (and only in that case), you can do
        that to call a method (MUIM_Foo,x) for each selected of them :

        DoMethod(L1, MUIM_NList_DoMethod, MUIV_NList_DoMethod_Selected,
          MUIV_NList_DoMethod_Entry, 2,
          MUIM_Foo,x);



MUIM_NList_DropDraw --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_DropDraw, LONG pos, LONG type,
                                          LONG minx,LONG maxx,LONG miny,LONG maxy);

    FUNCTION
        This method MUST NOT be called directly !

        It will be called by NList, and will draw the drop mark previously fixed
        (pos and type) by MUIM_NList_DropType within the minx, maxx, miny, maxy
        in the _rp(obj) rasport. You must not draw outside of the given box,
        because only the corresponding NList entry will be refreshed to erase what
        is drawn in that method.

        Calling the supermethod (so the builtin MUIM_NList_DropDraw method) will draw
        the standard dropmark specified by (type & MUIV_NList_DropType_Mask), so
        MUIV_NList_DropType_None,MUIV_NList_DropType_Above,MUIV_NList_DropType_Below
        or MUIV_NList_DropType_Onto.

        You can draw directly in the rastport (or a clone of it) in that method,
        because it will be called from the Draw method within the DragReport in
        Refresh mode.



MUIM_NList_DropEntryDrawErase --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_DropEntryDrawErase,LONG type,LONG drawpos,LONG erasepos);

    FUNCTION
        This method MUST NOT be called directly !

        It will be called by NList while the DragReport just before the redraw
        which will draw a new mark or erase the old one.

        This method can be used to change something so your displayhook will return
        something different for the marked entry, like changing its color or making
        it bold or italic.

        Don't call the superclass unless you know that the superclass use it.

        You should return 0.

    INPUTS
        type has the same meaning as *type in MUIM_NList_DropType, it will be useless
        in most cases (and has no meanning at all for erasepos).

        drawpos is the entry number which will be draw with a dropmark, -1 mean none.

        erasepos is the entry number which is not any more the dropmark one, -1 mean none.



MUIM_NList_DropType --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_DropType, LONG *pos,LONG *type,
                                          LONG minx,LONG maxx,LONG miny,LONG maxy,
                                          LONG mousex,LONG mousey);

    FUNCTION
        This method MUST NOT be called directly !

        It will be called by NList while the DragReport, with default *pos and *type
        values depending on the drag pointer position that you can modify as you want.

        Default *type can be MUIV_NList_DropType_Above or MUIV_NList_DropType_Below.
        You can change it to any of MUIV_NList_DropType_None,MUIV_NList_DropType_Above,
        MUIV_NList_DropType_Below and MUIV_NList_DropType_Onto if you want, using
        the mouse position and the entry box.

        You can make you own *type value as soon as you don't set it in
        MUIV_NList_DropType_Mask, and so draw what you want depending on that value
        in the MUIM_NList_DropDraw method.

        Note that any MUIV_NList_DropType_Below *type will be changed to
        MUIV_NList_DropType_Above with a *pos incremented by 1 just after the
        return of that method.

        If you change the *pos, the list will be scrolled to see it (if the value is
        correct).

        getting MUIA_NList_DropType or MUIA_NList_DropMark will return the same values
        as *pos and *type.

        If your subclass is a direct NList subclass, then there is no need to call
        the supermethod which done nothing at all !



MUIM_NList_Exchange --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_Exchange,LONG pos1, LONG pos2);

    FUNCTION
        Same function as List.mui/MUIM_List_Exchange.

    FUNCTION
        Same function as List.mui/MUIM_List_GetEntry.

    SPECIAL INPUTS
        MUIV_NList_GetEntry_Active    give active entry (or NULL if none)



MUIM_NList_GetEntryInfo --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_GetEntryInfo,struct MUI_NList_GetEntryInfo *res);

    FUNCTION
        You get usefull informations about some entry from its number,
        or from the real line number which can be different when there
        is word wrap in the list.

    INPUTS
        res - pointer to a MUI_NList_GetEntryInfo struct :
              LONG pos;       number of entry you want info about */
              LONG line;      real line number */
              LONG entry_pos; entry number of returned entry ptr */
              APTR entry;     entry pointer */
              LONG wrapcol;   NOWRAP, WRAPCOLx, or WRAPPED|WRAPCOLx */
              LONG charpos;   start char number in string (unused if NOWRAP) */
              LONG charlen;   string lenght (unused if NOWRAP) */

              if pos is MUIV_NList_GetEntryInfo_Line then the method will
              use the line number to search infos, else line will be set
              to its correct number for the value of pos.
              entry is the entry ptr, think that if it's a word wrapped
              entry then it come from the returned entry_pos entry.
              Think too that if wrapcol tell you that it's a WRAPPED entry,
              only the WRAPCOLx col is drawn, from the charpos position
              in the string returned by DisplayHook for the column and for
              entry_pos/entry.



MUIM_NList_GetPos --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_GetPos,APTR entry,LONG *pos);

    FUNCTION
        Give the (next) entry number which have the given entry number.
        It's the entry ptr which is stored in the list, ie the one returned
        by the ConstructHook if any.

    INPUTS
        entry - Entry ptr of the entry you want to get the pos.

        pos - a pointer to longword that will hold the next entry number
              of the given entry ptr. Must be set to MUIV_NList_GetPos_Start
              if you want to search from the beginning of the list.
              Is set to MUIV_NList_GetPos_End no more is found.




MUIM_NList_GetSelectInfo --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_GetSelectInfo,struct MUI_NList_GetSelectInfo *res);

    FUNCTION
        You get usefull informations about selected entries state.

    INPUTS
        res - pointer to a MUI_NList_GetSelectInfo struct :
        LONG start        num of first selected *REAL* entry/line (first of wrapped from which start is issued)
        LONG end          num of last selected *REAL* entry/line (first of wrapped from which start is issued)
        LONG num          not used
        LONG start_column column of start of selection in 'start' entry
        LONG end_column   column of end of selection in 'end' entry
        LONG start_pos    char pos of start of selection in 'start_column' entry
        LONG end_pos      char pos of end of selection in 'end_column' entry
        LONG vstart       num of first visually selected entry (ie can be the 2nd or 3rd line of a word wrap entry)
            LONG vend         num of last visually selected entry (ie can be the 2nd or 3rd line of a word wrap entry)
            LONG vnum         number of visually selected entries

    NOTE
        If no entry is selected, then start, end, vstart, vend are -1, vnum is 0.

        When start_column, end_column, start_pos, end_pos are -1 then the whole line/entry/column
        is selected.

        start_column, end_columb, start_pos and end_pos have the same meaning than
        parameters passed to the MUIA_NList_CopyEntryToClipHook.

        remember than in case of automatically added word wrapped entries, only
        the concerned column have any contents. You get that case for 'vstart'
        when 'start' is different, and for 'end' when 'vend' is different.

                  If count==-2 then entries must be a string pointer
                  which can be multiline with \n , \r or \r\n separators.
                  You'll get as many entries inserted as lines in the string.

                                           reordering of the columns. This could
                                           speed up the insert of entries very
                                           significant but will not automatically
                                           change the width of a column.

    INPUTS
        entry - Entry ptr of the entry (entries) you want to be redraw.



MUIM_NList_Remove --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_Remove,LONG pos);

    FUNCTION
        Same function as List.mui/MUIM_List_Remove.

    INPUTS
        pos - number of the entry to be removed or one of
              MUIV_NList_Remove_First
              MUIV_NList_Remove_Active
              MUIV_NList_Remove_Selected

              the following entry will become active.
              When the active is the removed and is the last,
              the new last become active.



MUIM_NList_ReplaceSingle --

    FUNCTION
        DoMethod(obj,MUIM_NList_ReplaceSingle,
                      APTR entry, LONG pos, LONG wrapcol, LONG align);

    FUNCTION
        Same function as MUIM_NList_InsertSingleWrap but replace an existing
        entry rather than inserting.
        It's better to do a direct replace than remove then insert it !

    INPUTS
        entry   - item to insert.

        pos     - position of the entry to be replaced
                MUIV_NList_Insert_Top     replace the first entry.
                MUIV_NList_Insert_Active  replace the active entry.
                MUIV_NList_Insert_Bottom  replace the last entry.
                Invalid positions will cause the replacement to fail!

        wrapcol - WRAPCOL0 to WRAPCOL6. You can't ask word wrap for an
                other col. NOWRAP if you don't want word wrap.
                So only one of (display hook) col 0 to 6 can be wrapped.

        align   - ALIGN_LEFT, ALIGN_CENTER, ALIGN_RIGHT or ALIGN_JUSTIFY.
                be aware that align will be used if there is no escape
                align sequence in the preparses or column entry string.

        DoMethod(obj,MUIM_NList_Select,LONG pos, LONG seltype, LONG *state);

    FUNCTION
        Same function as List.mui/MUIM_List_Select when in TypeSelect_Line mode.

        In TypeSelect_Char mode, MUIV_NList_Select_Off will clear the selected
        area (don't look what is pos). MUIV_NList_Select_On will select the
        pos entry only (can be MUIV_NList_Select_Active or MUIV_NList_Select_All).
        MUIV_NList_Select_Ask will give the number off entry in the selected area.

    INPUTS

                  be filled with the current selection state.



MUIM_NList_SelectChange -- Called on every selection change (V19.98)

    SYNOPSIS
        DoMethod(obj,MUIM_NList_SelectChange,LONG pos, LONG state, ULONG flags);

    FUNCTION
        This method cannot/should not be called. It's purpose is only to indicate
        selection state changes of entries in a more powerfull form than
        MUIA_NList_SelectChange does.
        It is only called when you are in line mode ie. MUIA_NList_TypeSelect is
        set to MUIV_NList_TypeSelect_Line, which is the default.

        pos     - The position of the (un)selected entry. Can be
                  MUIV_NList_Active_Off or something.
        state   - The resulting state of the entry which can be MUIV_NList_Select_On,
                  MUIV_NList_Select_Off or MUIV_NList_Select_Active.
        flags   - Can be MUIV_NList_SelectChange_Flag_Multi for now which means
                  that the entry was selected while holding down the mouse button.

    INPUTS



MUIM_NList_SetActive -- make a specific entry the active one (v20.125)

    SYNOPSIS
        DoMethod(obj, MUIM_NList_SetActive, LONG pos, ULONG flags);

    FUNCTION
        This method is a replacement function for the old-style way of making an
        entry active via a simple set(obj, MUIA_NList_Active, pos) call. While the
        old method still works, this new function has the advantage that it allows
        to set an entry active together with making it immediately visible in the
        listview.
        Previously, a developer had to do a combination of a set() call to set
        MUIA_NList_Active and then immediately perform a MUIM_NList_Jump function
        call so that the entry becomes visible at the specific position. With this
        new function both operations are combined, potentially allowing future
        enhancements to be added via the additional 'flags' variable.

    INPUTS
        The parameter description is as followed:

        pos     - The position (int) of the entry which should be made the new
                  active entry. This can also be MUIV_NList_Active_XXXX values as
                  explained in the MUIA_NList_Active documentation. Furthermore,
                  pos might also be perfectly a pointer to the entry directly in
                  case you have specified the correct flag.

        flags   - Can be a combination of the following flags:

                  MUIV_NList_SetActive_Entry:

                    the parameter 'pos' will be a pointer to the entry rather
                    than the position (int) of the entry to be made active. If
                    this flag is set NList will perform an internal GetPos()
                    operation to first obtain the position and then set
                    this entry active.

                  MUIV_NList_SetActive_Jump_Center:

                    Together with making the specified entry the new active one
                    the listview will also be scrolled so that the new entry
                    will be shown centered instead of having it simply visible.



MUIM_NList_SetColumnCol --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_SetColumnCol,LONG column,LONG col);

    FUNCTION
        set which displayhook col is at the visible column.

    INPUTS
        column  number of the column (visible).
                if MUIV_NList_SetColumnCol_Default then the given (diplayhook) col
                will come back to its default/original (from List_Format) position.

        col     col number (displayhook one).
                if MUIV_NList_SetColumnCol_Default then the given visible column
                will come back to its default/original (from List_Format) position.


                both set to MUIV_NList_SetColumnCol_Default make all columns
                come back to their default/original (from List_Format) position.

    RESULT
        None.

    NOTE
        MUIM_NList_SetColumnCol always exchange the moved column with the column
        which was were it move.



MUIM_NList_Sort --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_Sort);

    FUNCTION
        Same function as List.mui/MUIM_List_Sort.



MUIM_NList_Sort2 --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_Sort2,LONG sort_type, LONG sort_type_add);

    FUNCTION
        Same function as MUIM_NList_Sort but will set MUIA_NList_SortType
        before starting the sort.

        It is really usefull only if you use MUIA_NList_CompareHook2 instead
        of classic MUIA_NList_CompareHook so your hook will be able to do
        different type of sort when NList_SortType change.

    INPUTS
        sort_type     - The new MUIA_NList_SortType value (see below).

        sort_type_add - If 0 then sort_type will be the new MUIA_NList_SortType,
                        else if current MUIA_NList_SortType & MUIV_NList_SortTypeValue_Mask
                        is same as sort_type then sort_type_add will be added to the
                        MUIA_NList_SortType value,
                        else sort_type will be the new MUIA_NList_SortType.

                        See examples for special values.

    EXAMPLES
        Many times this method will be used to sort multicolumn list in different
        ways when the user click on title buttons :

        DoMethod(list,MUIM_Notify,MUIA_NList_TitleClick, MUIV_EveryTime,
          list, 3, MUIM_NList_Sort2, MUIV_TriggerValue, MUIV_NList_SortTypeAdd_xxx);

        if MUIV_NList_SortTypeAdd_None    then the hook sort_type value will be the column
                                          number.
        if MUIV_NList_SortTypeAdd_2Values then the hook sort_type value will be a cycle of
                                          values which change on each click :
                                          o Column number  (first time)
                                          o Column number + MUIV_NList_SortTypeAdd_2Values
                                          o back to column number ...

        if MUIV_NList_SortTypeAdd_4Values then the hook sort_type value will be a cycle of
                                          values which change on each click :
                                          o Column number  (first time)
                                          o Column number + MUIV_NList_SortTypeAdd_4Values
                                          o Column number + MUIV_NList_SortTypeAdd_4Values*2
                                          o Column number + MUIV_NList_SortTypeAdd_4Values*3
                                          o back to column number ...
        See NList-Demo program.



MUIM_NList_Sort3 --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_Sort3,LONG sort_type, LONG sort_type_add, LONG which);

    FUNCTION
        Same function as MUIM_NList_Sort2 but will set MUIA_NList_SortType,
        MUIA_NList_SortType2 or both before starting the sort.

        When using MUIV_NList_Sort3_SortType_Both the method will change
        MUIA_NList_SortType exactly the same way as MUIM_NList_Sort2 would do
        it, then copy that value to MUIA_NList_SortType2.

        It is really usefull only if you use MUIA_NList_CompareHook2 instead
        of classic MUIA_NList_CompareHook so your hook will be able to do
        different type of sort when NList_SortType change.

    INPUTS
        sort_type     - The new MUIA_NList_SortType/2 value.

        sort_type_add - If 0 then sort_type will be the new MUIA_NList_SortType/2,
                        else if current MUIA_NList_SortType/2 & MUIV_NList_SortTypeValue_Mask
                        is same as sort_type then sort_type_add will be added to the
                        MUIA_NList_SortType/2 value,
                        else sort_type will be the new MUIA_NList_SortType/2.

        which         - MUIV_NList_Sort3_SortType_1      set MUIA_NList_SortType value.
                        MUIV_NList_Sort3_SortType_2      set MUIA_NList_SortType2 value.
                        MUIV_NList_Sort3_SortType_Both   set MUIA_NList_SortType value
                                                         then copy it to MUIA_NList_SortType2.

    EXAMPLES
        See NList-Demo program.



MUIM_NList_TestPos --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_TestPos,LONG x, LONG y, struct MUI_NList_TestPos_Result *res);

    FUNCTION
        Find out which informations of a list which is currently
        displayed at a certain position.

        You must give a pointer to a valid MUI_NList_TestPos_Result struct.

        Set x AND y to MUI_MAXMAX to get infos about the last click position !

        See NList_mcc.h to know what values will be set in the struct.

        Preset char_number to -2 in the struct to not get char_number and char_xoffset
        informations. It's usefull if you don't need them because it will be
        faster for the method without finding them. the -2 value will stay valid
        for next call.

        You'll get char number from what you return from the DisplayHook if there is
        one, else from the beginning of the string/entry ptr.

        Be aware: if you use MUIM_List_TestPos you have to give a pointer to a
        struct MUI_List_TestPos_Result, and you'll get same infos as using a List object.
        It wasn't done as is before, makeing enforcer hits when trying to use NList
        or NFloattext with a Listview instead of a NListview (avoid it please, it's not
        done for it as Listview try to make many things itself, with possible conficts),
        because struct MUI_NList_TestPos_Result is bigger !!!

    NOTE
        column in the struct MUI_NList_TestPos_Result is the visible column number !



MUIM_NList_UseImage --

    SYNOPSIS
        DoMethod(obj,MUIM_NList_UseImage,Object *obj, ULONG imgnum, ULONG flags);

    FUNCTION
        If you want to use MUIM_NList_CreateImage/MUIM_NList_DeleteImage
        as you should, you must make a NList subclass which call them
        from Setup() and Cleanup(), and it's sometime complicated.

        To avoid that, you can use MUIM_NList_UseImage. NList will
        store the Bitmap/Bodychunk object you give and will make
        CreateImage and DeleteImage itself !

        MUIM_NList_UseImage can use same object as MUIM_NList_CreateImage !

        NULL is a valid obj. It will erase any previously UseImage
        with the same imgnum.

        The imgnum you give is the number that you will use in
        \33o[<n>] sequence as the <n> number.
        MUIM_NList_UseImage will accept 0 <= imgnum < 8192, anyway
        use small value if you can because an array will be allocated
        with the biggest imgnum value as size to store the
        Bitmap/Bodychunk objects.

        DoMethod(obj,MUIM_NList_UseImage, NULL, MUIV_NList_UseImage_All, 0)
        will set NULL to all stored objects, so you'll be able to dispose your
        Bitmap/Bodychunk objects if you want, without waiting the NList
        objet dispose.

        flags is the same than for MUIM_NList_CreateImage (0 unless special case).

    RESULT
        TRUE if succeeded to store the obj (and allocate the array
        if needed), else FALSE.

        There is no way to know if the MUIM_NList_CreateImage
        needed to draw will succeed/has succeeded.

        ATTENTION:
        The given Bitmap/Bodychunk object MUST be valid until the
        NList object is disposed or you set another object (or NULL)
        at the same imgnum !
        The Bitmap/Bodychunk object can be shared with other NList
        object because NList just use it to get informations, anyway
        you mustn't change informations of that object. If you to do
        so, do a UseImage,NULL,x , change it then do UseImage,imgobj,x
        again.

    There are two possible entry-types in a NListtree class list:
    Leaves and nodes. Leaves are simple entries which have no special
    features except they are holding some data. Nodes are almost
    the same type, holding data too, but having a list attached
    where you can simply add other entries which can be again leaves
    or nodes.

    Every node is structured as follows:

        struct MUI_NListtree_TreeNode {

            struct    MinNode    tn_Node;
            STRPTR    tn_Name;
            UWORD    tn_Flags;
            APTR    tn_User;
        };

    It contains a name field tn_Name, flags tn_Flags and a pointer to
    user data tn_User.

    The tn_Flags field can hold the following flags:

        TNF_LIST        The node contains a list where other nodes
                        can be inserted.

        TNF_OPEN        The list node is open, sub nodes are displayed.

        TNF_FROZEN        The node doesn't react on doubleclick or
                        open/close by the user.

        TNF_NOSIGN        The indicator of list nodes isn't shown.

        TNF_SELECTED    The entry is currently selected.

    These flags, except TNF_SELECTED, can be used in
    MUIM_NListtree_Insert at creation time. They will be passed to
    the newly created entry. Also you can do a quick check about the
    state and kind of each entry. But - NEVER EVER - modify any flag
    yourself or NListtree will crash. Be warned!

    *********************************************************************
        THE ABOVE STRUCT IS READ-ONLY!! NEVER CHANGE ANY ENTRY OF THIS
        STRUCTURE DIRECTLY NOR THINK ABOUT THE CONTENTS OF ANY PRIVATE
                        FIELD OR YOU WILL DIE IN HELL!
    *********************************************************************


    You can create very complex tree structures. NListtree only uses
    one list which holds all information needed and has no extra
    display list like other list tree classes ;-)

    The tree nodes can be inserted and removed, sorted, moved, exchanged,
    renamed  or multi  selected.  To sort you can also  drag&drop  them.
    Modifications can be made in relation to the whole tree, to only one
    level, to a sub-tree or to only one tree node.

    The user can control the listtree by the MUI keys, this means a node
    is opened with "Right" and closed with "Left". Check your MUI prefs
    for the specified keys.

    You can define which of the columns will react on double-clicking.
    The node toggles its status from open or closed and vice versa.


    Drag&Drop capabilities:

    If you set MUIA_NList_DragSortable to TRUE, the list tree will
    become active for Drag&Drop. This means you can drag and drop
    entries on the same list tree again. While dragging an indicator
    shows where to drop.

        Drag a    Drop on        Result

        leaf    leaf        Exchange leaves.
        node    leaf        Nothing happens.
        entry    closed node    Move entry, the compare hook is used.
        entry    open node    Move entry to defined position.

    You can not drop an entry on itself, nor can you drop an opened node on
    any of its members.

    To exchange data with other objects, you have to create your own
    subclass of NListtree class and react on the drag methods.



MUIA_NListtree_Active -- [.SG], struct MUI_NListtree_TreeNode *


   SPECIAL VALUES

        MUIV_NListtree_Active_Off
        MUIV_NListtree_Active_Parent
        MUIV_NListtree_Active_First
        MUIV_NListtree_Active_FirstVisible
        MUIV_NListtree_Active_LastVisible


   FUNCTION

    Setting this attribute will move the cursor to the defined tree node
    if it is visible. If the node is in an opened tree the listview is
    scrolling into the visible area. Setting MUIV_NListtree_Active_Off will
    vanish the cursor.

    MUIV_NListtree_Active_First/FirstVisible/LastVisible are special values
    for activating the lists first or the top/bottom visible entry.

    See MUIA_NListtree_AutoVisible for special activation features.

    If this attribute is read it returns the active tree node. The result
    is MUIV_NListtree_Active_Off if there is no active entry.


   NOTIFICATIONS

    You can create a notification on MUIA_NListtree_Active. The
    TriggerValue is the active tree node.





MUIA_NListtree_ActiveList -- [..G], struct MUI_NListtree_TreeNode *

   SPECIAL VALUES

        MUIV_NListtree_ActiveList_Off


   FUNCTION

    If this attribute is read it returns the active list node. The
    active list node is always the parent of the active entry.
    The result is MUIV_NListtree_ActiveList_Off if there is no
    active list (when there is no active entry).


   NOTIFICATIONS

    You can create notifications on MUIA_NListtree_ActiveList. The
    TriggerValue is the active list node.




MUIA_NListtree_AutoVisible -- [ISG], struct MUI_NListtree_TreeNode *

   SPECIAL VALUES

        MUIV_NListtree_AutoVisible_Off
        MUIV_NListtree_AutoVisible_Normal
        MUIV_NListtree_AutoVisible_FirstOpen
        MUIV_NListtree_AutoVisible_Expand


   FUNCTION

    Set this to make your list automatically jump to the active
    entry.

        MUIV_NListtree_AutoVisible_Off:
            The display does NOT scroll the active entry into the
            visible area.

        MUIV_NListtree_AutoVisible_Normal:
            This will scroll the active entry into the visible area
            if it is visible (entry is a member of an open node).
            This is the default.

        MUIV_NListtree_AutoVisible_FirstOpen:
            Nodes are not opened, but the first open parent node of
            the active entry is scrolled into the visible area if the
            active entry is not visible.

        MUIV_NListtree_AutoVisible_Expand:
            All parent nodes are opened until the first open node is
            reached and the active entry will be scrolled into the
            visible area.





MUIA_NListtree_CloseHook -- [IS.], struct Hook *

   SPECIAL VALUES


   FUNCTION

    The close hook is called after a list node is closed, then you can
    change the list.

    The close hook will be called with the hook in A0, the object in A2
    and a MUIP_NListtree_CloseMessage struct in A1 (see nlisttree_mcc.h).

    To remove the hook set this to NULL.




MUIA_NListtree_CompareHook -- [IS.], struct Hook *

   SPECIAL VALUES

        MUIV_NListtree_CompareHook_Head
        MUIV_NListtree_CompareHook_Tail
        MUIV_NListtree_CompareHook_LeavesTop
        MUIV_NListtree_CompareHook_LeavesMixed
        MUIV_NListtree_CompareHook_LeavesBottom


   FUNCTION

    Set this attribute to your own hook if you want to sort the entries in
    the list tree by your own way.

    When you sort your list or parts of your list via MUIM_NListtree_Sort,
    using the insert method with MUIV_NListtree_Insert_Sort or dropping an
    entry on a closed node, this compare hook is called.

    There are some builtin compare hooks available, called:

        MUIV_NListtree_CompareHook_Head
            Any entry is inserted at head of the list.

        MUIV_NListtree_CompareHook_Tail
            Any entry is inserted at tail of the list.

        MUIV_NListtree_CompareHook_LeavesTop
            Leaves are inserted at top of the list, nodes at bottom. They are
            alphabetically sorted.

        MUIV_NListtree_CompareHook_LeavesMixed
            The entries are only alphabetically sorted.

        MUIV_NListtree_CompareHook_LeavesBottom
            Leaves are inserted at bottom of the list, nodes at top. They are
            alphabetically sorted. This is default.

    The hook will be called with the hook in A0, the object in A2 and
    a MUIP_NListtree_CompareMessage struct in A1 (see nlisttree_mcc.h). You
    should return something like:

        <0    (TreeNode1 <  TreeNode2)
         0    (TreeNode1 == TreeNode2)
        >0    (TreeNode1 >  TreeNode2)




MUIA_NListtree_ConstructHook -- [IS.], struct Hook *

   SPECIAL VALUES

        MUIV_NListtree_ConstructHook_String

        MUIV_NListtree_ConstructHook_Flag_AutoCreate
            If using the KeepStructure feature in MUIM_NListtree_Move or
            MUIM_NListtree_Copy, this flag will be set when calling your
            construct hook. Then you can react if your hook is not simply
            allocating memory.


   FUNCTION

    The construct hook is called whenever you add an entry to your
    listtree. The pointer isn't inserted directly, the construct hook is
    called and its result code is added.

    When an entry shall be removed the corresponding destruct hook is
    called.

    The construct hook will be called with the hook in A0, the object in
    A2 and a MUIP_NListtree_ConstructMessage struct in A1 (see
    nlisttree_mcc.h).
    The message holds a standard kick 3.x memory pool pointer. If you want,
    you can use the exec or amiga.lib functions for allocating memory
    within this pool, but this is only an option.

    If the construct hook returns NULL, nothing will be added to the list.

    There is a builtin construct hook available called
    MUIV_NListtree_ConstructHook_String. This expects that the field
    'tn_User' in the treenode is a string pointer (STRPTR), which's
    string is copied.
    Of course you have to use MUIV_NListtree_DestructHook_String in
    this case!

    To remove the hook set this to NULL.

    NEVER pass a NULL pointer when you have specified the internal string
    construct/destruct hooks or NListtree will die!




MUIA_NListtree_CopyToClipHook -- [IS.],

   SPECIAL VALUES

        MUIV_NListtree_CopyToClipHook_Default


   FUNCTION

        This thing works near like MUIA_NListtree_DisplayHook, but is
        called when the NListtree object want to make a clipboard copy.

        You can return only one string pointer. If you return NULL,
        nothing will be copied. If you return -1, the entry will be
        handled as a normal string and the name field is used.

        The builtin hook skips all ESC sequences and adds a tab char
        between columns.





MUIA_NListtree_DestructHook -- [IS.], struct Hook *

   SPECIAL VALUES

        MUIV_NListtree_DestructHook_String


   FUNCTION

    Set up a destruct hook for your listtree. The destruct hook is called
    whenevere you remove an entry from the listtree. Here you can free memory
    which was allocated by the construct hook before.

    The destruct hook will be called with the hook in A0, the object
    in A2 and a MUIP_NListtree_DestructMessage struct in A1 (see
    nlisttree_mcc.h).
    The message holds a standard kick 3.x memory pool pointer. You must
    use this pool when you have used it inside the construct hook to
    allocate pooled memory.

    There is a builtin destruct hook available called
    MUIV_NListtree_DestructHook_String. This expects that the 'User' data
    in the treenode is a string and you have used
    MUIV_NListtree_ConstructHook_String in the construct hook!

    To remove the hook set this to NULL.




MUIA_NListtree_DisplayHook -- [IS.],

   SPECIAL VALUES


   FUNCTION

    You have to supply a display hook to specify what should be shown in
    the listview, otherwise only the name of the nodes is displayed.

    The display hook will be called with the hook in A0, the object in
    A2 and a MUIP_NListtree_DisplayMessage struct in A1 (see nlisttree_mcc.h).

    The structure holds a pointer to a string array containing as many
    entries as your listtree may have columns. You have to fill this
    array with the strings you want to display. Check out that the array
    pointer of the tree column is set to NULL, if the normal name of the
    node should appear.
    You can set a preparse string in Preparse for the corresponding col
    element. Using it you'll be able to avoid copying the string in a
    buffer to add something in the beginning of the col string.

    The display hook also gets the position of the current entry as
    additional parameter. It is stored in the longword preceding the col
    array (don't forget it's a LONG).

    You can set the array pointer of the tree column to a string, which is
    diplayed instead of the node name. You can use this to mark nodes.

    See MUIA_NList_Format for details about column handling.

    To remove the hook and use the internal default display hook set this
    to NULL.

   FUNCTION

    A doubleclick opens a node if it was closed, it is closed if the node
    was open. You have to set the column which should do this.

    Normally only the column number is set here, but there are special
    values:

        MUIV_NListtree_DoubleClick_Off:
            A doubleclick is not handled.

        MUIV_NListtree_DoubleClick_All:
            All columns react on doubleclick.

        MUIV_NListtree_DoubleClick_Tree
            Only a doubleclick on the defined tree column is recognized.

        MUIV_NListtree_DoubleClick_NoTrigger:
            A doubleclick is not handled and not triggered!


   NOTIFICATION

    The TriggerValue of the notification is the tree node you have double-
    clicked, you can GetAttr() MUIA_NListtree_DoubleClick for the column
    number. The struct 'MUI_NListtree_TreeNode *'is used for trigger.

    The notification is done on leaves and on node columns, which are not
    set in MUIA_NListtree_DoubleClick.

MUIM_NListtree_NextSelected -- Get next selected tree node. (V1)

   SYNOPSIS

    DoMethod(obj, MUIM_NListtree_NextSelected,
        struct MUI_NListtree_TreeNode **treenode);


   FUNCTION

    Iterate through the selected entries of a tree. This method steps
    through the contents of a (multi select) list tree and returns
    every entry that is currently selected. When no entry is selected
    but an entry is active, only the active entry will be returned.

    This behaviour will result in not returning the active entry when
    you have some other selected entries somewhere in your list. Since
    the active entry just acts as some kind of cursor mark, this seems
    to be the only sensible possibility to handle multi selection
    together with keyboard control.


   INPUTS

    treenode -  A pointer to a pointer of struct MUI_NListtree_TreeNode
                that will hold the returned entry. Must be set to
                MUIV_NListtree_NextSelected_Start at start of iteration
                and is set to MUIV_NListtree_NextSelected_End when
                iteration is finished.

        MUIV_NListtree_NextSelected_Start    Set this to start iteration.
        MUIV_NListtree_NextSelected_End        Will be set to this, if
                                            last selected entry reached.

    steps through the contents of a (multi select) list tree and returns
    every entry that is currently selected. When no entry is selected
    but an entry is active, only the active entry will be returned.

    This behaviour will result in not returning the active entry when
    you have some other selected entries somewhere in your list. Since
    the active entry just acts as some kind of cursor mark, this seems
    to be the only sensible possibility to handle multi selection
    together with keyboard control.


   INPUTS

    treenode -  A pointer to a pointer of struct MUI_NListtree_TreeNode
                that will hold the returned entry. Must be set to
                MUIV_NListtree_PrevSelected_Start at start of iteration
                an the end and is set to MUIV_NListtree_PrevSelected_End
                when first selected entry is reached and iteration is
                finished.

        MUIV_NListtree_PrevSelected_Start    Set this to start iteration.
        MUIV_NListtree_PrevSelected_End        Will be set to this, if
                                            last selected entry reached.


   RESULT

   EXAMPLE

    // Iterate through a list (reverse)
    struct MUI_NListtree_TreeNode *treenode;

    treenode = MUIV_NListtree_PrevSelected_Start;

    for (;;)
    {
        DoMethod(listtree, MUIM_NListtree_PrevSelected, &treenode);

            struct MUI_NListtree_TreeNode *treenode,
            STRPTR newname, ULONG flags);


   FUNCTION

    Rename the specified node.

    If you want to rename the tn_User field (see flags below), the construct
    and destruct hooks are used!
    If you have not specified these hooks, only the pointers will be copied.

    DoMethod(obj, MUIM_NListtree_Select,
        struct MUI_NListtree_TreeNode *treenode, LONG seltype,
        LONG selflags, LONG *state);


   FUNCTION

    Select or unselect a tree entry or ask an entry about its state.
    See special values for completeness.


   INPUTS

    treenode -    The tree node to be selected/unselected/asked.

        MUIV_NListtree_Select_Active    For the active entry.
        MUIV_NListtree_Select_All        For all entries.
        MUIV_NListtree_Select_Visible    For all visible entries.

    seltype -    Type of selection/unselection/ask

        MUIV_NListtree_Select_Off        Unselect entry.
        MUIV_NListtree_Select_On        Select entry.
        MUIV_NListtree_Select_Toggle    Toggle entries state.
        MUIV_NListtree_Select_Ask        Just ask about the state.

    selflags -    Some kind of specials.

        MUIV_NListtree_Select_Flag_Force
            Adding this flag to seltype forces the selection by
            bypassing the multi test hook.

    state -        Pointer to a longword. If not NULL, it will be filled
                with the current selection state of the entry.


   RESULT

   EXAMPLE

        // Select the active entry.
        LONG retstate;

        DoMethod(obj, MUIM_NListtree_Select,
            MUIV_NListtree_Select_Active, MUIV_NListtree_Select_On,
            0, &retstate);

        // We must check this, because the multi test hook may
        // cancel our selection.
        if (retstate == MUIV_NListtree_Select_On) {
            ...
        }


   NOTES

    If ( treenode == MUIV_NListtree_Select_All ) and
    ( seltype == MUIV_NListtree_Select_Ask ), state will be filled
    with the total number of selected entries.

    NEW for final 18.6:
    If (treenode == MUIV_NListtree_Select_Active ) and
    ( seltype == MUIV_NListtree_Select_Ask ), state will be the
    active entry, if any, or NULL.

    If only the active entry is selected, has a cursor mark (see
    MUIM_NListtree_NextSelected for that), you will receive 0 as
    the number of selected entries.

That MCC public custom class give scrollers for a NList public custom class to make NList/NListview work near the same way as List/Listview. Most things that were handled by Listview are now handled by NList, so NListview is quite simple, anyway it's very easier to use NList with NListview than without.

Anyway, use NList without NListview if you don't want to get attached scrollers (or want to attach your own scrollers to NList - see Demo). 

Note: NListview class can't use List as child but only NList, NFloattext, or a NList subclass, and NList class will not work with Listview without some conflict.


MUIA_NListview_Horiz_ScrollBar -- [ISG], Object *

        MUIV_NListview_HSB_Auto        2
        MUIV_NListview_HSB_FullAuto    3
        MUIV_NListview_HSB_None        4
        MUIV_NListview_HSB_Default     5

    SPECIAL SPECIAL INPUTS
        MUIV_NListview_HSB_On          0x0300
        MUIV_NListview_HSB_Off         0x0100

    FUNCTION
        With it you can tell if you want the scrollbar to be here
        always, never, automatic (not at start and appear forever if
        needed) or full automatic (appear and disappear when needed).

        Never is interesting if you want only one scrollbar of both
        or if you want to attach your own one only for one scrollbar.

        With Auto and FullAuto modes, scrollbars will not appear at
        first draw of the window. If you want it to appear when the
        window will be opened, you can set after creation time (not
        at init) MUIA_NListview_Horiz_ScrollBar
        to (MUIV_NListview_HSB_XXX|MUIV_NListview_HSB_On) where XXX
        is Default, FullAuto ...

        MUIV_NListview_HSB_On, MUIV_NListview_HSB_Off are used by the
        NList object to make scrollbars appear/disappear.

        The default is set by prefs. When prefs have not been set
        it is MUIV_NListview_HSB_Auto.



MUIA_NListview_HSB_Height -- [..G], LONG

    FUNCTION
        Return the height of the horizontal scrollbar.

        Return 0 when no horizontal scrollbar is visible.



MUIA_NListview_NList -- [I.G], Object *

    FUNCTION
        Same function as Listview.mui/MUIA_Listview_List.

        Every NListview needs a NList (or subclass) object as child.
        You should specify it here.

        If you don't specify one, NListview will create a NList object
        as child, giving it the same taglist as itself.
        It's the only case where NList tags given to NListview will be
        taken into account.

        As every other child, it will get disposes when its parent object is disposed.



MUIA_NListview_Vert_ScrollBar -- [ISG], Object *

        MUIV_NListview_VSB_Off         0x0010

    FUNCTION
        Same as MUIA_NListview_Horiz_ScrollBar but for vertical
        scrollbar.

        The default is set by prefs. When prefs have not been set
        it is MUIV_NListview_VSB_Always.



MUIA_NListview_VSB_Width -- [..G], LONG

    FUNCTION
        Return the width of the vertical scrollbar.

        Return 0 when no vertical scrollbar is visible.

NFloattext[edit]

NFloattext class is a subclass of NList class that takes a big text string as input and splits it up into several lines to be dislayed. Formatting capabilities include paragraphs an justified text with word wrap. That MCC public custom class  work near the same way as Floattext.

All you can do with NFloattext can be done directly using NList and its word wrap capabilities. NFloattext is here to give easy use and transition from Floattext.

Now NList package provide a Floattext.mui replacement which use directly this class. Unfortunately the replacement Floattext.mui have to have the same major release number than original Floattext.mui to be accepted by MUI, so it will have to be update with each new MUI release. 

By default, MUIA_NList_Input is FALSE and MUIA_NList_TypeSelect is MUIV_NList_TypeSelect_Char, alowing char selection and copy to clipboard. If you set MUIA_NList_Input to TRUE, then MUIA_NList_TypeSelect default to MUIV_NList_TypeSelect_Line as usual. 

NFloattext does not copy the string text, so it needs to copy the string line to a buffer when you do a MUIM_NFloattext_GetEntry or MUIM_List_GetEntry, so the return pointer will be invalid after next GetEntry call (the new one will be valid of course). 

Using the old MUIA_Floattext_Text from standard Floatext class instead of MUIA_NFloattext_Text will make NFloattext copy the text like in Floattext class.

Note that MUIM_NList_GetEntry work as describe in NList, so as NFloattext use word wrap entries, you should use better MUIM_NFloattext_GetEntry or MUIM_List_GetEntry. Or use MUIM_NList_GetEntryInfo and MUIM_NList_GetEntry.



MUIA_NFloattext_Align -- [ISG], LONG

    SPECIAL INPUTS
        ALIGN_LEFT
        ALIGN_CENTER
        ALIGN_RIGHT
        ALIGN_JUSTIFY

    FUNCTION
        Indicate what alignment you want.
        It can be done with an escape alignment sequence
        in the Format preparse string or in the text string
        (for each linefeed separated lines) itself.

        setting it will set MUIA_NFloattext_Justify to
        TRUE if ALIGN_JUSTIFY, else to FALSE.



MUIA_NFloattext_Justify -- [ISG], BOOL

    FUNCTION
        Same as Floattext.mui/MUIA_Floattext_Justify.

        if TRUE, MUIA_NFloattext_Align will be set to
        ALIGN_JUSTIFY, else to ALIGN_LEFT.



MUIA_NFloattext_SkipChars -- [ISG], char *

    FUNCTION
        Same as NList.mcc/MUIA_NList_SkipChars
        and Floattext.mui/MUIA_Floattext_SkipChars.




MUIA_NFloattext_TabSize -- [ISG], LONG

    FUNCTION
        Same as NList.mcc/MUIA_NList_TabSize
        and Floattext.mui/MUIA_Floattext_TabSize.

        Tab size defaults to 8.




MUIA_NFloattext_Text -- [ISG], STRPTR

    FUNCTION
        Same as Floattext.mui/MUIA_Floattext_Text.

        String of characters to be displayed as floattext.
        This string may contain linefeeds or carriage retruns to mark
        the end of paragraphs or tab characters for indention.

        NFloattext will automatically format the text according
        to the width of the NFloattext object. If a word
        won't fit into the current line, it will be wrapped.

        NFloattext don't copies the string into a private buffer
        as Floattext do it, so you need to keep your text in
        memory, but it uses less memory.

        If you want NFloattext to copy the text, just use
        MUIA_Floattext_Text which will do it for compatibility.

        Setting MUIA_NFloattext_Text to NULL means to clear
        the current text.

        Please note that justification and word wrap is a
        complicated operation and may take a considerable
        amount of time, especially with long texts on slow
        machines.





MUIM_NFloattext_GetEntry --

    SYNOPSIS
        DoMethod(obj,MUIM_NFloattext_GetEntry,LONG pos, APTR *entry);

    FUNCTION
        Same function as List.mui/MUIM_List_GetEntry.

        You'll get pointer to a null terminated string buffer which
        is a copy of the asked visible entry.

        Unlike with Floattext, the returned string will be valid only
        until next MUIM_NFloattext_GetEntry/MUIM_List_GetEntry call
        if the entry was word wrapped.
        I'll try to make it stay valid when using MUIM_List_GetEntry
        only if someone report me some compatibility problem because
        doing that will use more memory.



NBalance[edit]

NBalance.mcc/NBalance.mcc
NBalance.mcc/MUIA_NBalance_Pointer


This MCC public custom class is derived from the MUI standard balance class which handles the dragging/resizing of vertical and horizontal groups.

In contrast to the standard MUI balance class, however, it adds some features such as displaying a mouse pointer as soon as the mouse is above a dragable NBalance object.



MUIA_NBalance_Pointer -- [ISG.], LONG

    INPUTS
        MUIV_NBalance_Pointer_Off
        MUIV_NBalance_Pointer_Standard (default)

    FUNCTION
        Allows to set the mouse pointer that should be displayed when
        the mouse is found to be above a NBalance object. Per default
        a standard horizontal or vertical size pointer is displayed as
        soon as the mouse is above a dragable NBalance object.



NBitmap[edit]

Creating a custom class[edit]

Most likely when creating a custom class you will want to extend the existing classes functionality, like providing a new appearance, handling keys, etc. Zune provides an interface to do so. The newly created class can be "private" to your application, or "public" and thus available to other applications like any existing (built-in or public custom) class.

To create you own custom class...

available on Aminet - look for DisKo

If you want to make your new custom class publicly available, e. g. to be included in AROS, it is necessary to register a class base address / class ID - to avoid conflicts with other developers developing a public custom class.
