Where is the kBscTabWidgetID referenced by the group as border widget?

Include a FittedStaticTextWidget as first item in the widget list, same level as that ClusterPanelWidget.

Your quoted .fr fragment only has one occurence of kBscTabWidgetID.

For a deeper understanding of the resource language, try to follow the declarations ( e.g. starting in Widgets.fh ) and comment every line / data item.

An example of the relevant entry, formatted my way:

GroupPanelWidget (
    // GroupPanelWidget : CControlView
    kBscGroupWidgetID,                      // WidgetId
    kPMRsrcID_None,                         // RsrcId
    kBindNone,                              // Frame Binding
    Frame(                                  //  Frame
        0, 60,                              //  left,top
        150, 115 )                          //  right,bottom
    kTrue,                                  // Visible
    kTrue,                                  // Enabled
    // GroupPanelWidget : GroupPanelAttributes
    kBscTabWidgetID,                        // widget id of border widget
    // GroupPanelWidget : CPanelControlData
    {
    ...
    }
)


Then use the interface ID of e.g. GroupPanelAttributes to locate the matching .h interface header:

class IGroupPanelAttributes : public IPMUnknown

{

public:

  // ----- Query -----

          enum { kDefaultIID = IID_IGROUPPANELATTRIBUTES };

  /** Get the widget id of the widget to use in the top left border of the GroupPanel. 

                              The widget can have sub-widgets.  If GetBorderWidgetID returns 0,

                              a simple framed border will be drawn.

                    @return the widget id

          */

          virtual WidgetID          GetBorderWidgetID() const = 0;

...

This will give you more details on the meaning of the values in the resource.
