dynamic menus

[Dan McMahill <mcmahill mtl mit edu>]

Hello,

I have two questions about menus in gtk.  I've created the menus via an 
xml description and the gtk UI manager.

Question #1

  - is it possible to keep certain menuitems in the xml and the 
associated GtkActionEntry but toggle if they are visible or not? 
Something like gtk_widget_hide() and gtk_widget_show()?  Or do I have to 
basically tear down the menus, regen the xml and create the menus again?

Question #2

  - What does it take to change the text in some menus that already 
exist?  Do I have to do
  gtk_ui_manager_remove_action_group()

  then create a new action group, insert to the ui manager and call 
gtk_action_group_add_actions?

Or is there a simpler way?

Thanks
-Dan
