Re: GtkItemFactory

["Donna S. Martin" <donna omartin com>]

That is the way to do it if you bear in mind two things.
1) An item factory callback has a different prototype than
a menu item callback.
2) That field is shared among all the callbacks you specify in the
GtkItemFactoryEntry array.

The most common error is number 1.  Here is the prototype for
an Item Factory Callback.....
  void (*GtkItemFactoryCallback1)( gpointer callback_data,
guint callback_action, GtkWidget *widget);

A bit different from a MenuItem callback.  Of course, if you don't like
this,
you could always retrieve the widget id from the item factory and
attach your callback manually.  Then you'd be using the GtkMenuItem's
callback prototype.

Does this make sense? Hope so, if not I'll try again.
