i is a local var of the tracePath() method; it can't be accessed outside
this method, and it doesn't even exist after tracePath() has finished
executing.
What you are trying to do is dynamically create N instances of a
UIComponent, and when you click one of them, you want to know whether it
is the 1st, 2nd, ... one that you created. (Actually, I suspect that
what you really want to get when you click is the 'results' data,
because otherwise I don't know why you calculated it.)
The best way to do this is to write a trivial subclass of UIComponent
which can store 'i' and/or 'results' as an instance var of each
UIComponent that you create:
public class MyComponent extends UIComponent
{
public class MyComponent()
{
super();
}
public var i:int;
public var results:XMLList;
}
Inside tracePath(), create instances of MyComponent and set 'i' and/or
'results' on each one:
var myUIComponent:MyComponent = new MyComponent();
myUIComponent.i = i;
myUIComponent.results = results;
myUIComponent.graphics...
Then inside mouseClickHandler() you can access 'i' and 'results' as
event.currentTarget.i and event.currentTarget.results. You can't access
them as this.i and this.results because 'this' is always whatever
component or application your <mx:Script> is inside of; it isn't the
object that dispatched or listened to the MouseEvent.
BTW, you could probably accomplish of all this more easily by using the
<mx:Repeater> tag, but that's another topic.

Subject: [flexcoders] accessing variables through events
Quick question regarding accessing variables.
I have the following code
public function tracePath():void {
for (var i:int = 0; i < photoFeed.menu.submenu.length(); i++) {
trace([EMAIL PROTECTED])
var results:XMLList =
[EMAIL PROTECTED];
trace(results);
trace (i);
var myUIComponent:UIComponent = new UIComponent();
myUIComponent.graphics.beginFill(0xFFCC00);
myUIComponent.graphics.drawCircle(60*i, 30, 30);
myUIComponent.buttonMode = true;
myUIComponent.useHandCursor = true;
myUIComponent.addEventListener(MouseEvent.CLICK,
mouseClickHandler);
this.addChild(myUIComponent);
}
trace(photoFeed.menu.submenu.length() +"hello");
}
and I access using this function
public function mouseClickHandler(event:MouseEvent):void{
trace(this.i);
}
My question is... how do I access the "i" variable from within the
mouseClickHandler() function
so I could find out certain properties. The above code does not seem to
find the "i" based on the dynamically created component.
I really want to be able to find out the list collection based on click.
Thanks
Jeremy
