Capture phase never happens for timer event

Question

I am trying to comprehend event flow, event bubbling,
listeners, etc. I created a test class called TimerExample to
generate some events. It kinda works, but the eventListeners
listening for the event during the capture phase are never
triggered. Does this mean timer events don't bubble? Is there some
good rule of thumb for which events bubble and which do not? If
there's no rule of thumb, is there some list or reference in the
on-line flash docs?

Answer 1

Looking at Adobe's fl.controls.BaseButton class shows the
pattern you need. Find the file by searching for a file called
"BaseButton.as" on your computer, and if you find more than one,
it's the one inside the "controls" folder inside the "fl" folder.
It shows a good pattern to use when you want a Timer event to
bubble. In the BaseButton class, repeating BUTTON_DOWN events are
broadcast when anything that extends BaseButton is pressed and held
by the user.
Basic flow:
1. The class listens for all MouseEvent events with the same
handler: mouseEventHandler()
2. If mouseEventHandler(event:MouseEvent) gets an event of
type MouseEvent.MOUSE_DOWN, it calls startPress.
3. The startPress() method starts the pressTimer instance of
Timer
4. The Timer is calling buttonDown() every millisecond.
(really?)
5. The buttonDown() method dispatches the BUTTON_DOWN
component event with bubbling set to true.
Hope this helps.
