[gcompris-devel] help needed in event handling

[bruno]

What happen is that each time you call colors_create_item(), you do a:

gtk_signal_connect(GTK_OBJECT(gcomprisBoard->canvas), "event", 
(GtkSignalFunc) item_event, NULL);

and thus assign another time the callback !!

This command should be done once in your case.

What I don't unnderstant it's why it's no more called when we quit the
boards ?
