Hi,
we have started developing an application using qooxdoo for ui inside
google wave gadgets. And here is my question:
I want to create some kind of custom event. I haven't found much
documentation on that.
The wave api offfers to specify a callback function (and a context for
the callback) for state updates, which can be regarded as a very general
event. I want to distinguish this general event. Depending on the data
stored in the state object, i want to fire some special events. So what
I need is one object - maybe event handler is my friend? - which has a
member function, let's say fireMyEvents, which is set as callback for
the state update event. fireMyEvents analyses the state data and fires
events on all objects that were added a certain custom event type.
Actually that would do what I want. But I am not so familiar with
events, so I explain what I want to end up with. Maybe I need something
totally different.
At the end, I want to use something like
mbj = new MyCustomObject(); // supports event type "myEvent"
mbj.setId("myId"); //sets Id property
mbj.addListener("myEvent", myFire());
If the state data is updated and contains myId in some specified way,
myEvent is fired on for mbj.
That was what I want. I guess the distinction of the object ID is done
by a member function of MyCustomObject. But I still need to start it on
state updates for every object that was added myEvent listener. And I
can only specify one callback :-( How do I get started?
Thanks for your excellent work on qooxdoo!!
