Oh, I see. Yes, getting menu & toolbar button sensitivity working well is a
pain. Though I think allowing groups of widgets to be made insensitive only
helps a little. You often still have to write a function like
set_interface_state() in glade_menu_editor.c to work out which widgets should
be sensitive.

Oops. I thought you meant inserting rows. GtkCList doesn't support adding &
removing columns dynamically, unfortunately. So you have to remove it and
add a new GtkCList.

(Actually it is easier to change the <columns> setting in the XML file directly.)

You'll have to create the submenus yourself, and call gtk_menu_item_set_submenu()
to add them to the parent menu items. (Make sure you don't show the menus though.)
