    You should use this gtk_object_set/get_data(). 
    It's really simple, and very powerfull !

    To get the parent of a widget, you can use 
    GTK_WIDGET(yourwidget)->parent. By iterate this 
    until you find a NULL parent, you should do the 
    trick.
    
    As a conclusion, I don't think there is a get_toplevel_window()
    in gtk+. So you should use one of two method here (or
    another, if you found one).
