callback problems

[Michael Stevens <esuci dcs warwick ac uk>]

Hi.
        I'm having problems with callbacks on click events on buttons.

I've got a button having a callback connected with:
  gtk_signal_connect_object(GTK_OBJECT(fui->go_button), "clicked",
                            GTK_SIGNAL_FUNC(go_func),
                            (gpointer)fui);
        
Where the callback function is defined as:
void go_func(GtkWidget *widget, gpointer data) {

        /* do some stuff */

}                                                                               And I've hit a very weird bug where consistently the value of 'widget'
is the value 'data' should have, and 'data' contains garbage. Its
consistent enough that I've worked around it by doing:
data = (gpointer)widget;
                
and not using the widget pointer.

Any help/ideas?
