hello,
i have a little problem with the listbrowser-gadget and the horizontal-props.
the size of the horizontal-slider-knob is too little when the x-size of all columns is (some points ) bigger then the window (gadget). then you can scroll very large and at the end you can see the columns again.
in the first i think i have a problem with the code in my program, but i also can produce this problem with the example-program "twocolumn" from the sdk. is this a bug in the listbrowser-gadget or is my use of the gadget-parameters wrong???

i modify only this:
deaktivate AUTOFIT
activate HorizontalProp
modify the sizes of window and columns.

here the code-lines (sorry i can not add an attachment):

columninfo = IListBrowser->AllocLBColumnInfo(2,
LBCIA_Column, 0,
LBCIA_Title, " GUI Attributes",
LBCIA_Width, 290,
LBCIA_Column, 1,
LBCIA_Title, " BOOL",
LBCIA_Width, 120,
TAG_DONE);

return IIntuition->NewObject(NULL, "window.class",
WA_ScreenTitle, "ReAction Example",
WA_Title, "Two Column Example",
WA_DragBar, TRUE,
WA_CloseGadget, TRUE,
WA_SizeGadget, TRUE,
WA_DepthGadget, TRUE,
WA_Activate, TRUE,
WA_InnerWidth, 320,
WA_InnerHeight, 300,
WINDOW_IconifyGadget, TRUE,
WINDOW_IconTitle, "Iconified",
WINDOW_AppPort, AppPort,
WINDOW_Position, WPOS_CENTERSCREEN,
WINDOW_Layout, IIntuition->NewObject(NULL, "layout.gadget",
LAYOUT_Orientation, LAYOUT_ORIENT_VERT,
LAYOUT_SpaceOuter, TRUE,
LAYOUT_AddChild, IIntuition->NewObject(NULL, "layout.gadget",
LAYOUT_Orientation, LAYOUT_ORIENT_VERT,
LAYOUT_SpaceOuter, TRUE,
LAYOUT_BevelStyle, BVS_GROUP,
LAYOUT_Label, " GUI Tags ",

LAYOUT_AddChild, OBJ(OBJ_LISTBROWSER) = IIntuition->NewObject(NULL, "listbrowser.gadget",
GA_ID, OBJ_LISTBROWSER,
GA_RelVerify, TRUE,
GA_TabCycle, TRUE,
//LISTBROWSER_AutoFit, TRUE,
LISTBROWSER_Labels, &listbrowser_list,
LISTBROWSER_ColumnInfo, columninfo,
LISTBROWSER_ColumnTitles, TRUE,
LISTBROWSER_ShowSelected, TRUE,
LISTBROWSER_HorizontalProp,TRUE,
LISTBROWSER_Striping, LBS_ROWS,
TAG_DONE),

i hope someone can help me.

@turbo4.1

Modified your code a bit to my liking, but the main points I changed are:
In AllocLBColumnInfo:
replaced LBCIA_Width witg LBCIA_Weight
added (draggable) separators

Added a (n emply) list to the listbrowser
In the Listbrowser I added this tag:
LISTBROWSER_AutoVirtualWidth, TRUE,
and gave the object a minimum width:
CHILD_MinWidth, 260,

Code: Select all

BOOL MainBody(struct ExecParam *xn)
{
INFO_ENTER
  BOOL Success = FALSE; 

  if ((PD->pd_ColumnInfo = IListBrowser->AllocLBColumnInfo(2, LBCIA_Column, 0,
                                                              LBCIA_Title, " GUI Attributes",
                                                              LBCIA_Weight, 30,
                                                              LBCIA_DraggableSeparator, TRUE,
                                                              LBCIA_Separator, TRUE,

                                                              LBCIA_Column, 1,
                                                              LBCIA_Title, " BOOL",
                                                              LBCIA_Weight, 10,

                                                              TAG_DONE)))
   {
    if ((PD->pd_List = IExec->AllocSysObjectTags(ASOT_LIST, TAG_END)))
     {
        WindowStandardObject(WOID_MAIN),
          WA_IDCMP,    0
                      | IDCMP_CLOSEWINDOW
                      | IDCMP_GADGETUP
                        ,

          WINDOW_MainBox(BOXID_MAIN),
            LAYOUT_Orientation, LAYOUT_VERTICAL,

            LAYOUT_NamedBox(BOXID_CURRENT, "Current project"),

              LAYOUT_ListBrowser(GOID_FILENAME, NULL, PD->pd_List, PD->pd_ColumnInfo),
                LISTBROWSER_HorizontalProp,   TRUE,
                LISTBROWSER_AutoVirtualWidth, TRUE,
                LISTBROWSER_VertSeparators,   TRUE,
                LISTBROWSER_Striping,         LBS_ROWS,
              LAYOUT_ListBrowserEnd,
              CHILD_MinWidth, 260,

            LAYOUT_NamedBoxEnd,
 
          WINDOW_MainBoxEnd,

        WindowObjectEnd;

        Success = Handle_WindowObject(xn, WOID_MAIN, WID_MAIN);

      IExec->FreeSysObject(ASOT_LIST, PD->pd_List);
      PD->pd_List = NULL;
     }
    ELSE_ERROR("Allocate SysObject (struct List)");

    IListBrowser->FreeLBColumnInfo(PD->pd_ColumnInfo);
    PD->pd_ColumnInfo = NULL;
   }
  ELSE_ERROR("Allocate LB ColumnInfo");

INFO_VACATE
  return Success;
}

The code for the LISTBROWSER macro:

Code: Select all

#   define LAYOUT_ListBrowser(GadID, HintInfo, Labels, ColumnInfo)                \
   LAYOUT_AddChild,                                                               \
    GE->ge_GadObj[GadID] = (Object*) IIntuition->NewObject(ListBrowserClass, NULL,\
       GA_ID,                  GadID,                                             \
       GA_HintInfo,            HintInfo,                                          \
       GA_RelVerify,           TRUE,                                              \
       GA_TextAttr,            xn->xn_FixedFont,                                  \
       LISTBROWSER_Labels,     Labels,                                            \
       LISTBROWSER_Spacing,    STD_GADGET_SPACE,                                  \
       LISTBROWSER_ColumnInfo,      ColumnInfo,                                   \
       LISTBROWSER_ColumnTitles,   (ColumnInfo)?(TRUE):(FALSE),                   \
       LISTBROWSER_VertSeparators,  TRUE

#   define LAYOUT_ListBrowserEnd  0UL)

Hope you may have some help from this.
Btw: I tested it and it looks 'nice'.
