vertical scroll bar not visible on StdListBoxWidgetN

[user6965273]

Hi,

I am using StdListBoxWidgetN for creating a dynamic list wherein insertation to/deletion from the list happen dynamically. When the number of items in list exceeds the number of  items that can be displayed in the list, it is expected that vertical scroll bar will appear and I should be able to scroll the list vertically. However this not happening. The vertical scroll bar doesn't appear and I can scroll down t access the last added items. The .fr content for the list is as follows:

type WMSlDlgTreeViewWidget2 (kViewRsrcType) : StdListBoxWidgetN(ClassID = kStdListBoxWidgetNewBoss)
{
WidgetEveInfo;
};

WMSlDlgTreeViewWidget2

(

kSelectDialogSelectionWidgetID, 

kSysOwnerDrawListBoxPMRsrcId,// WidgetId, RsrcId

kBindAll,

Frame(15,15,400,225), // Frame

kTrue, 

kTrue, // Visible, Enabled

kTrue, // EraseBeforeDraw

kInterfacePaletteFill, // InterfaceColor

//"",

//kHideRootNode | kDrawBorder, //Options

1,                                                        // Border width

kFalse,                                                  // Has scroll bar (h)

kTrue,                                                    // Has scroll bar (v)

kFalse,                                                  // Multiselection

kFalse,                                                  // List items can be reordered

kFalse,                                                  // Draggable to new/delete buttons

kFalse,                                                  // Drag/Dropable to other windows

kFalse,                                                  // An item always has to be selected //kFalse

kTrue,                                                    // Notify on reselect

Hi,

I think there is one line with "0," too much in the middle of the list.
