List/Enumeration of Elements in a View (WD for Java)

Question

Hello,
How do I get a complete list of all elements in a view at runtime?
I want to dynamically modify 30+ elements, but I don't want to have to code each of them. Is there a way to do this?
Thanks,
Martin

Martin,
Try something like this:
static interface IAction
  abstract public void execute(IWDUIElement el);     
static class CollectElements implements IAction
  final private Map _result = new TreeMap();
  public Map result() { return Collections.unmodifiableMap(_result); }
  public void execute(final IWDUIElement el)
    _result.put( el.getId(), el );       
void traverse(final IWDView view, final IAction action)
  traverse( (IWDUIElementContainer)view.getRootElement(), action );
void traverse(final IWDUIElementContainer container, final IAction action)
  action.execute(container);
  for (final Iterator i = container.iterateChildren(); i.hasNext(); )
    final IWDUIElement el = (IWDUIElement)i.next();
    if ( el instanceof IWDUIElementContainer )
      traverse( (IWDUIElementContainer)el, action );
    else
      action.execute( el );
Sample:
final CollectElements selectAll = new CollectElements();
traverse(wdView, selectAll);
/* Now selectAll.result() contains id->element mapping */
This will not collect Table columns, or Tabs in TabStrib, however you can create "dispatching" IAction implementation, that delegates to some custom methods like traverse(IWDTable) or traverse(IWDTabStrip)
