[flexcoders] Looking for AS3 developer.
HeyZap is looking for an AS3 developer to build a AS/flash wrapper that rotates through 3rd party external SWF files, solving issues with sizing, sound, keyboard/mouse controls. They dont want the Flex framework used, but a pure AS project compiled in FB is fine. Email for more details. This company is run by a friend of mine - please send replies to me, and I'll pass them on to him. tom saffell
[flexcoders] Re: Closures in ActionScript 3?
Just a shot in the dark here... I could be completely wrong, I dont use
closures much in AS.
Does AS3 have block scope? (I suspect not). If not, then you're recycling the
variable 'input' each time you loop. So each time you add a new event listener
to 'input', you're adding it to all your TextInput instances. Just a guess -
I've never tried it..

Could someone please explain to me how closures work in ActionScript? I
am attempting to create a set of Flex Form fields, and assign an
event-handler to each of them, however, it seems that after creation,
all of the fields have the same event handler.
For example:
var i:int = 0;
for each (var item:Object in this._myItems) {
var f:FormItem = new FormItem();
f.label = item.header;
var input:TextInput = new TextInput();
// Setup event-handler
var self:MyClass = this;
input.addEventListener(change, function (e:Event):void
{
Alert.show(Event-hanlder #: + String(i));
});
i++;
// Add text input to FormItem
f.addChild(input);
// Save a reference to the form control
item.ui = f;
addChild(f);
}
So I would expect that the number displayed when I change any given
field matched the order of the field on the screen. When I run the code,
however, no matter which field I adjust, the number is always the same
(it is the number of the last form item to be added).
It appears that what is happening is that a single function is being
created, and each input field has a reference to that same function.
Any suggestions? Any help would be greatly appreciated.
Thanks!

[flexcoders] Re: Flash Speed test - RESULTS !
Wow! The penchant for tangets here is staggering. @Tom Chiverton - there a few scenarios where someone would be wise to ask for a frame rate above 30 fps (but probably not none) - but that does not mean that information on how browsers react to Flash apps asking for frame rates 30 FPS is useless. The Flex SDK allows for the frame rate to be 'set' up to 1000 FPS (per the documentation) so there is some value in developers knowing how a browser reacts to that. The tests around 24 FPS are more interesting to me. tom --- In flexcoders@yahoogroups.com, Paul Andrews p...@... wrote: That's the standard refresh rate for a lot of LCD monitors.. - Original Message - From: Thibaud Van Vreckem To: flexcoders@yahoogroups.com Sent: Wednesday, May 13, 2009 6:31 PM Subject: Re: [flexcoders] Flash Speed test - RESULTS !

An alternative (if you dont need the unserialized data server side) is
to use byteArray. I pasted below a very scrappy example of how to get

[flexcoders] Re: How to get an object to delete itself?
Thanks Paul and Haykel.
That works (it removes the child from the display), but one curious
thing remains:
When I uic.addChild then uic.numChildren increments by 1.
But when call this.owner.removeChild(this) then uic.numChildren does
not decrement by 1.
(uic is my UIComponent to which I'm adding these graphics)
Is this behavior to be expected?

To remove the control from its parent's display list, you should use:
this.parent.removeChild(this);
Another method could be to dispatch an event when the timer fires,
listen
for it in the parent and remove the control in the event handler.
Yet another suggestion: You could also implement a
DrawingToolsManager which
would create DrawingTool objects on demand, add them to a container and
remove them when a timer event fires.

This will require that you remove it from the Display list and

So your destruct method needs (at least):
this.owner.removeChild(this); // remove this instance from the

I have custom class that extends UIComponent which I use for putting

UIComponent).
In the constructor I create a Timer and watch for the
TIMER_COMPLETE event,
at which point I want the graphic to dissapear, which I do by
setting alpha
= 0.
However, I am concerned that it will not be garbage collected, and
I could
end up with quite a few of these, which may be bad for memory.
Question: Can i get the object to delete itself? (or atleast be in
a state
suitable for grabage collection)
e.g. this.selfDestruct() ;)
The relevant code is shown below.
