2748.0. "How to get the widget_ids?" by KLEE::SCHMIDT (Christiane Schmidt, @KLE Germany) Fri May 11 1990 08:59

    One simple question:
    
    I define in UIL the main_widget with all its controls ...
    
    I open the UID-hierarchy with the routine DwtOpenHierarchy.
    
    Is there a way to find out the widget_ids of all the widgets
    in the opened hierarchy? I think with the routine DwtFetchWidget
    i can only fetch widgets, which do not hang in any hierarchy
    defined in UIL.
    
    I can get the widget_id by defining a callback_procedure. But
    i liked to get the id in another way.
    
    Any ideas?
    
    Thanks

    Using "create" callbacks is the better way of getting the widget id.
    Alternate is to use the function XtNameToWidget(top-level-widget,names)
    See the "XUI toolkit intrinsics manual (C bindings)" section 11.2
    "Utility functions"

    The DECburger approach to this problem works pretty well.  Having a
    table with every widget ID your application uses is overkill sometimes,
    but the flexibility of easy access to any widget ID is worth it.
