Hi folks

I am building a composite wiget as a learning exercise.  I declared
callback handlers for each of the active widget types I am using :

   package Window_Callback_Pkg is new
     Gtk.Handlers.Callback (Gtk.Window.Gtk_Window_Record);

   package Image_Menu_Item_Callback_Pkg is new
     Gtk.Handlers.Callback
(Gtk.Image_Menu_Item.Gtk_Image_Menu_Item_Record);

   package Button_Callback_Pkg is new
     Gtk.Handlers.Callback (Gtk.Button.Gtk_Button_Record);

Following communication with folks on the list it has occurred to me
that I need not work so hard.  I think I could simply write one
instantiation :

   package Widget_Callback_Pkg is new
      Gtk.Handlers.Callback (Gtk.Widget.Gtk_Widget_Record);

which would cover all eventualities.  Am I right about this?

Has at least one penny dropped?
