[gtkada] Tooltips for Status_Bars do not pop up

[Schroeer, Joachim Dr., MSOP32]

Dear GtkAda team members,
 
I am experimenting with tooltips and have problems to get them working for Status_Bars. The tip windows do not pop up. My code looks like this.

------------------------------------------------------------------- 
with gtk. ...;
package <Window>_Pkg is
 
  type <Window>_Record is new Gtk_Window_Record with record
    ...
    Vb_Main        : Gtk_Vbox;
    Main_Statusbar : Gtk_Statusbar;
    Tooltips       : Gtk_Tooltips;
   end record;
  ...
end;
 
with gtk. ...;
package body <Window>_Pkg is

  procedure Initialize (<Window> : access <Window>_Record'Class) is
  begin
    ...
    Gtk_New_Vbox (<Window>.Vb_Main, False, 0);
    ...
    Add (<Window>, <Window>.Vb_Main);
    Gtk_New (<Window>.Main_Statusbar);
    Pack_Start (<Window>.Vb_Main, <Window>.Main_Statusbar, False, False, 0);
    gtk.tooltips.Gtk_New (<Window>.Tooltips);
    Set_Tip (Tooltips => Tooltips,
             Widget   => <Window>.Main_Statusbar,
             Tip_Text => "Main Status Bar: Explanation" & ascii,lf & ...);
    Enable (Tooltips);
    Force_Window (Tooltips)
  end Initialize;

end;
------------------------------------------------------------------- 

If the tooltip is attached to the Vbox VB_Main the tip texts do also not appear. If it is attached to <Window> the text appears.

Thanks for any hints.
