Re: [flexcoders] Re: Binding using as3
It will be faster if you just hand-code the equivalent of:
[Bindable] private var _y:int
as:
private var __y;
private function get _y():int
{
return __y;
}
private function set _y(value:int):void
{
if (value != __y)
{
__y = value;
dispatchEvent(new Event(“_yChanged”));
}
}
Then whocares() can be coded like this:
private function whocares():void
{
var vtiA:MyTextInput = new MyTextInput;
addEventListener(“_yChanged”, function(e:Event) {vtiA.x =
event.target[“_y”]);
vtiA.x = _y
}

I was suprised that you were binding a private variable - that only
makes sense if your code is sitting inside that class.
I don't know the context of this, but if you had a setter, you might be
able to do the same as when binding.
I have to say that _y is a bit confusing since y is the natural public
accessor for a private variable _y and y is the actual position of an
element and _y seems to be something else!

[flexcoders] Re: Binding using as3
Paul,
BTW I did try BindingUtils.bindProperty(vtiA,"x",this,"_y"); and it did not
seem to work for me. It recognized _y as it required that I change it to a
public variable.

[flexcoders] Re: Binding using as3
Paul,
Thanks for the links. I looked at them, and followed their links, but
everything seemed to point to two complex objects. What I have is a simple
object, a string, that when it is updated, I need the new value to be "pushed"
to the property of a complex object, a custom textinput component, so that the
next time a method of that object is fired, it will know of the changed value.
Paul
