hi,
I have a question to eventbus handling:
when do I have to remove handlers from the eventbus via
HandlerRegistration.removeHandler() ?
In our application an activity is a presenter as well.
The docs of Activity say:
/**
* Called when the Activity's widget has been removed from view. All
event
* handlers it registered will have been removed before this method is
called.
*/
void onStop();
/**
* Called when the Activity should ready its widget for the user.
* ...
* <p>
* Any handlers attached to the provided event bus will be de-registered
when
* the activity is stopped, so activities will rarely need to hold on to
the
* {@link com.google.gwt.event.shared.HandlerRegistration
HandlerRegistration}
* instances returned by {@link EventBus#addHandler}.
* ...
*/
void start(AcceptsOneWidget panel, EventBus eventBus);
So, does this mean, I don't have to care about unregistering handlers
within my presenter/activity because this is done automatically?
Consecutive starts of an activity/presenter that will register handlers in
their start-method will *NOT* cause duplicate registrations of the same
handler ?
I browsed the GWT sources (2.5.1) but didn't find a concluding answer to
this.
TIA
Kibu
