Don't know, if it's the correct way, but for me (and extending
ListBox) this was the only thing I had to do to make DoubleClick-
handling work:
...extends ListBox implements HasDoubleClickHandlers...
public HandlerRegistration addDoubleClickHandler(DoubleClickHandler
handler) {
return addDomHandler(handler, DoubleClickEvent.getType());
}
as far as I understood HandlerManager is already an instance in
Widget, so you don't need to create your own, when you extend an
existing widget.

Could I please get some clarification on how to use the double click
event handling? The classes are there
(e.g.http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/g...)
but don't seem to be implemented anywhere.
I would like to add double click handling to an Image, could someone
please give me some example snippet of code on how to do this? I've
tried simple things like extending Image and implementing
HasDoubleClickHandlers, e.g.
private class CommandButton extends Image implements
DoubleClickHandler, HasDoubleClickHandlers {
private HandlerManager clickHandlers = new
HandlerManager(this);
public CommandButton(){
super(images/favicon-2.png);
addDoubleClickHandler(this);
}
@Override
public void onDoubleClick(DoubleClickEvent event) {
Log.debug(doubleclicked command button);
}
@Override
public HandlerRegistration
addDoubleClickHandler(DoubleClickHandler
handler) {
return
clickHandlers.addHandler(DoubleClickEvent.getType(),
handler);
}
@Override
public void fireEvent(GwtEvent? event){
handlers.fireEvent(event);
}
}
but of course this doesn't handle double click events.
Thanks!
