Default event propagation

Please Login to Remove!

Hi. What is the proper way to propagate an event to calling objects ? For example, I have a sub-classed button that's in a manager. On button click, I want to process the navClick event in the button itself and also raise it up to the manager to do some work there based on the click trigger.

I figured out that I can do it by either passing the manager reference to the button and invoking a manager method from the button. Or creating an interface that the manager would implement and calling it from the button event handler.

Is there a better way to do this ?

Thanks.

navigationClick returns true if the consumed the event, false otherwise. You could return false which would indicate to the system that it should find another target for the event. This may not be the object you want. Better? Perhaps, if it does what you want.

Thank you for the idea. It almost worked. The event bubles up to the manager. The problem is that now the manager navClick does the same thing as the button navClick, which I do not want. In other words, if I click anywhere in the manager, it does the same thing as if I clicked on the button inside the manager. I am not sure if it's possible to trace the originating control of the event. navClick has only status and time params.
