Re: Destroy a widget

When you create two HelloWorld widgets each of them receives its own events. If you use @UiHandler in your UiBinder widget and you want to stop receive events for a widget without removing the widget itself from the parent (for whatever reason) you have to "disable" your @UiHandler implementation.

So you would end up having

@UiHandler(...)

void onEvent(...) {

  if(handleEvents) {

     //do your event logic

  }

}

or you use a Delegate interface that a class can implement and that contains your event logic implementation:

@UiHandler(...)

void onEvent(...) {

  if(delegate != null) {

     delegate.onEvent();

  }

}

In that case you would disable your events by nulling your delegate: widget.setDelegate(null)

Otherwise you have to remove the widget from the parent.
