If it were me trying to solve this problem, I would look to the
qx.event.message.Bus system. Inside your event listener, you will dispatch
an event of a type you create and pass along the information that other
parts of the program would want access to. It might look like this:
object_my_class.addEventListener("changeSelected", function ()
{
qx.event.message.Bus.dispatch(new
qx.event.message.Message('my_class_change_selected',
object_my_class.someproperty));
});
then for the other parts of the program to get at that event you simply
subscribe to that message, like this:
qx.event.message.Bus.subscribe('my_class_change_selected',
function(message){
var theData = message.getData(); // returns the data you supplied in the
creation of the message event
// do something with theData here...
})
I have found the message Bus to be a very powerful thing and have learned to
love it!
