Re: GtkItemFactoryEntry question

["Donna Martin" <donna omartin com>]

The widget supplied is the one which activated
the callback (GTK+ supplies this for you) - in this
case the New menu item since that's what you clicked
on to activate the hello function.

The gpointer data is supplied by you, in your
gtk_item_factory_create_items().  It's any data
you need to pass to the function (as long as it
fits in a gpointer).  My assumption is that your
hello isn't using this field, since it's prototype is
actually, according to the RDP :

void        (*GtkItemFactoryCallback1)      (gpointer callback_data,
                                             guint callback_action,
                                             GtkWidget *widget);

different from a typical widget signal handler......

Hope that helps.
Donna
