In the example below, the callback_function will be
executed everytime the user clicks on the "close"
WM decoration (the cross you mention). The callback
has 3 arguments, not 2! If you return FALSE your
window will get closed!

Carlos

gint callback_function (GtkWidget *widget,
GdkEventButton *event, gpointer data)
{

return TRUE;
}

gtk_signal_connect (GTK_OBJECT (window), "delete_event",
                    GTK_SIGNAL_FUNC (callback_function), data);
