It is documented, in two places: 1) ActionScript Language Reference: http://www.adobe.com/livedocs/flex/201/langref/flash/events/EventDispatc her.html In the method detail for flash.events.EventDispatcher.addEventListener() see the description of the priority parameter: If two or more listeners share the same priority, they are processed in the order in which they were added. 2) Programming ActionScript 3.0 (chapter on Event Handling) http://www.adobe.com/livedocs/flex/201/html/16_Event_handling_172_6.html #119538 See the subsection titled Adding Event Listeners and the paragraph that discusses the priority parameter.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML
Yes that's possible, but semantically it is slightly different.
Inside the binding tag, the sequence of function calls is given by the
sequence in your code.
If you use mulitple addEventListener calls the sequence is not guaranteed.
Another possibility, which maintains the sequence, would be to use an
anonymous function
myButton.addEventListener( MouseEvent.CLICK, function(){
myFunction1();
myFunction2();
myFunction3();
})
Cheers,
Ralf.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML
Ralf,
That is an interesting approach.
I just have never had the need for something like that.. yet.
Didn't I read somewhere that the order you add listeners is the order they
get dispatched in as3 now? Plus you can use priorities.
PS From an OOP standpoint, I wouldn't do it , I would just write a wrapper
method that calls it. Much better from a maintainence aspect and intent
aspect.

That's correct.
Plus you can use priorities.
This can be tricky, as the framework uses different priorities for
various purposes. If you need to ensure the order in which multiple
event handlers get called, try to add them in the right order.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML
Object.addEventListener( click, [funct1, funct2, funct3] ); No, 1. as3 is strongly typed which means the method expects a function when it is getting an array. 2. addEventListener wouldn't even know what to do with an array. You could, if you had your own subclass override addEventListener to do that but, you could also just create a stack of functions in an array if they were all going to the same event and loop through them to save code lines. It's personal choice when you get to this point. Peace, Mike On 2/7/07, Mike Anderson [EMAIL PROTECTED] wrote: Hey Doug, Well, that's simple enough.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML
could be renamed in a future release to something like mouseClick and then your code wouldn't work. Or even worse, you write cllck, and then for days even months, you think your app isn't working or 'works' a certain way. Come to find out the event wasn't even getting captured. :) This is plain ole preventative maintainence. That is the worse case for me, renaming events is small potatoes to that error. ;-) Peace, Mike On 2/7/07, Doug McCune [EMAIL PROTECTED] wrote: Nope, I think the second parameter must be a function, trying to pass an array of functions should fail.

So you can add 2 or more event listeners that get triggered for the same event. So something like: myButton.addEventListener(MouseEvent.CLICK, myFunction1); myButton.addEventListener(MouseEvent.CLICK, myFunction2); myButton.addEventListener(MouseEvent.CLICK, myFunction3); All three of the above functions would get called when the event triggers. You can remove each of these separately as well by using removeEventListener and specifying the particular function you want removed.

Re: [flexcoders] Re: Object.addEventListener vs.. adding them inline via MXML
Mike, Looks like you're speaking from personal experience :) From now on I'll make my custom components dispatch click and cilck and cllck and clik etc etc. The google suggest approach to event dispatching.
