Hey Nils,

I'm guessing you didn't have previous experience with libbonoboui menus.

Hmm, I don't know why it isn't showing. Is it showing the "Remove" menuitem?

> 2. What's the <placeholder> for ?

placeholder is for menu merging. For example if you have 

"<ui>"
"  <menubar name='MainMenu'>"
"    <menu name='FileMenu' action='FileMenu'>"
"      <menuitem action='New'/>"
"      <placeholder name='FileMenuAdditions'/>"
"      <menuitem action='Exit'/>"
"    </menu>"
"  </menubar>"
"</ui>"

once you create a GtkUIManager etc with it. you can do something like

gtk_ui_manager_add_ui_from_string with a new string

<ui>
  <menubar name='MainMenu'>
    <menu name='FileMenu' action='FileMenu'
    <placeholder name='FileMenuAdditions'/>
      <menuitem action='Save'/>
    </placeholder>
    </menu>
  </menubar>
</ui>

So the Save menuitem will show up after 'New' and before 'Exit' menuitem.

after constructing GtkUIManager etc, you can do something like

GtkWidget *foo;
foo = gtk_ui_manager_get_widget (ui_manager, "/MainMenu/FileMenu");
gtk_widget_hide (foo);

to hide the menu.

I think ur looking.

GtkAction*  gtk_ui_manager_get_action       (GtkUIManager *self,
                                             const gchar *path);
