RE: [flexcoders] Re: Is there a way to find an object if you know the name

[Gordon Smith]

There should be no need to set the 'name' property to a different value on each instance of a repeated component so that you can retrieve that instance. If you have   <mx:Repeater ...>     <mx:Button id="b" ... /> </mx:Repeater>   then the various repeated Button instances are accessible as b[0], b[1]. Using this "indexed id" access is faster than using getChildByName(), and you don't waste memory storing names.   - Gordon   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Michael Labriola Sent: Monday, October 16, 2006 5:17 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Is there a way to find an object if you know the name   Marlon, So long as you know the container where the child exists, you can say: container.getChildByName(name:String):DisplayObject or container.getChildIndex(child:DisplayObject):int Hope that helps, Mike --- In [EMAIL PROTECTED]ups.com, "Marlon Moyer" <marlon.moyer@...> wrote: > > sorry, I didn't phrase the question correctly.
