Re: [Flashcoders] AS3 MouseEvent target?
This behaviour can not emulated precisely because there is no way for us to set the target and currentTarget properties. This is done by internal EventDispatcher code. The EventDispatcher code works something like this: - check if the target property of the event has been set, if not set it - set the currentTarget property - check if the event has the bubbles property set to true - check if the class is a DisplayObject - check if the parent property is set - clone the event and dispatch it at the parent and repeat the above steps Greetz Erik On 4/2/08, Meinte van't Kruis <[EMAIL PROTECTED]> wrote: > > so how does it work internally for displayObjects?

Re: [Flashcoders] AS3 MouseEvent target?
Extending DisplayObject to access some of its native functionality (e.g. event bubbling) seems fine to me, especially if you look at it from the perspective of EventDispatcher has events and DisplayObject extends EventDispatcher and adds bubbling functionality. If you need bubbling, extend the class that provides that. The whole non-visual argument is a bit of a red herring considering we're using Flash and, until recently, all Actionscript was inside of or attached to a display object (MovieClip). Technically, it still is. ;) Flash is a visual tool, and I maximize my productivity by leveraging it fully. Flash has all kinds of great Flash-centric features and you can definitely use them to your advantage. It's not "hacking" to use the API given to you. :) ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

the problem with most explanations about event bubbling is that it concentrates on the displaylist (understandable), i'd like to see an example of custom events being bubbled.

Re: [Flashcoders] AS3 MouseEvent target?
You shouldn't be using capture phase until you've got a really good
handle on bubbling phase first.
You shouldn't have bubbling turned on for your button unless you are
planning on catching this event above this clip, as well.
Event Bubbling means that the TextField is dispatching a bubbling event
automatically and you are catching it because you're listening to the
clip that contains the TextField for the CLICK event. You're going to
receive the TextField CLICK even though you want just the MovieClip
CLICK. You set mouseChildren = false so you don't receive events from
anything but the MovieClip.
Take off the true flag for bubbling and set mouseChildren = true. This
should solve your issue.

Yes, it's Event Bubbling that's causing the target to be the
TextField. To understand Event Bubbling, read about it in the
docs, or better yet, in a book (like Moock's). But, then you MUST
do it yourself to learn how it works. If you don't play with it
yourself, you will never "get it" no matter how much somebody
explains it to you. I'm fully convinced of that. You gotta mess
around with it to fully understand why it's so amazingly awesome.

A perfect opportunity for someone more eloquent than I to explain event

[Flashcoders] AS3 MouseEvent target?
hi guys
in actionscript 3, if i put a mouse event on a movieclip object
containing a textfield, should the mouse event be on the movieclip or
the textfield?
here's my code (comments added to see where the problem is occurring)
CODE

the periodBars where they will fit without overlapping

because the movieclip isn't always the target (even tho i've set the

rolloverText (because it's trying to find the variable rolloverText
