RE: dialog widget problem

[Matt Eisemann <meisemann dsrnet com>]

You were right.  For some reason it needed gtk_signal_connect_object.  If I 
want to also have a window delete handler in case they close the window via 
window mgr does the following look right given the variable names I have 
used already.

gtk_signal_connect(GTK_OBJECT(dialog_win),"delete_event",
 
                            GTK_SIGNAL_FUNC(utics_ok_delete_handler),NULL);

gboolean utics_ok_delete_handler(GtkWidget *widget, GdkEvent *event,
                                                  gpointer user_data)
{
  gtk_widget_hide(widget);
  return(TRUE);
}

Actually, i just tried it and I got a core dump.  Anything look wrong 
above.  Thanks ahead of time for your help.

Matt

Just a thought...  It appears the problem has to do with 
gtk_signal_connect()
passing it's first argument to gtk_widget_hide() whereas I think your 
trying to
pass the last argument instead.  Try using gtk_signal_connect_object(), it 
will
change the order of the argments passed to the callback function so that 
the
last argument to gtk_signal_connect_object() is passed as the first 
argument to
gtk_widget_hide() instead.
