Re: How to pass data to GtkItemFactory callback?

[MALHERBE <malherbe hugues wanadoo fr>]

The way to pass data to your GtkItemFactory callbacks is done thru the 
fonction

void gtk_item_factory_create_items( GtkItemFactory      *ifactory,
                                   guint                n_entries,
                                   GtkItemFactoryEntry *entries,
                                   gpointer             callback_data) 

*ifactory a pointer to the above created item factory.

n_entries is the number of entries in the GtkItemFactoryEntry array.

*entries is a pointer to the GtkItemFactoryEntry array.

callback_data is what gets passed to all the callback functions for all 
the entries with callback_action != 0.

In your array of GtkItemFactoryEntry (perl_file_select_menu), you must 
set the 4th parameter (called callback_action) to a value different from 0.

And the prototype of each GtkItemFactory callback is :

void callback( 	gpointer    callback_data,
	           guint       callback_action,
                  GtkWidget  *widget )

You can refer to the tutorial at the following links :

I hope it can help you.
