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.
