Re: Activities Places: How to listen to PlaceChangeEvents without an Activity?
Hi,
PlaceChangeEvents are fired on the EventBus that you passed into your
PlaceController. So you can listen to them via:
eventBus.addHandler(PlaceChangeEvent.TYPE, new PlaceChangeEvent.Handler() {
//implement method
})
-- J.

Re: Activities Places: How to listen to PlaceChangeEvents without an Activity?
Thank you. Works pretty well :)
Is that GWT's new EventHandler structure? I mean: XyzEvent.Handler? No
more seperate Handler class?
And XyzEvent.TYPE instead of getType()? I like both changes pretty
much :)

Re: Activities Places: How to listen to PlaceChangeEvents without an Activity?
I don't think this is really new
You can also define a CustomClass implements PlaceChangeEvent.Handler {}
then addHandler(PCE.TYPE, new CustomClass());
As for the .TYPE vs getType(), I do not know the details but if you look at
PlaceChangeEvent extends GwtEvent it has the static field TYPE
but a dom event like ClickEvent still has getType()

Re: Activities Places: How to listen to PlaceChangeEvents without an Activity?
DomEvent-s have their types lazily created, because they're registered in a global, er, registry, to easily match event types (from the browser, evt.type, i.e. a string such as click, mouseover, etc.) to DomEvent.Type instances. Most other events don't need this, but some of them could benefit from it: some events have a static fire() helper method; when invoked, if the TYPE private field hasn't been initialized, it means getType() hasn't been called, i.e. no handler has been registered for the event, so the fire() help method can exit early, without event creating an event instance and calling the event bus. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
