This is pretty easy, but also pretty usefull.
It removes all the children of a given object. You can use with Flex or Flash.

Muito fácil, mas também muito útil.
Remove todos os filhos de um dado objeto. Você pode usar com Flex ou Flash.
These (localToGlobal and globalToLocal) are very useful methods that might be not as well known as they should. As now I’m a blogger, and I just wrote code using it, I took some time to draw a (I think) very didactid image about it. There’s no source, no code. Just read the figue and you should be able to understand.
And a warning: there are other pair of methods in Flex (globalToContent and contentToGlobal), which are intended to be used when your containers have borders.

Enjoy.
And here we have another example:
I am an onPress orphan. Now I said it… How do you know your user is efectively pressing something? Of course, you say, there is the MOUSE_DOW, but noooo, I want to know he is pressing all the time he is pressing.
So, here’s my ugly hack for me beloved onPress.
/******************************/
Sou uma órfã do onPress. Pronto, falei… Como você sabe que seu usuário está efetivamente pressionando alguma coisa? É claro, você pensa, tem o MOUSE_DOWN, mas nããããão, eu quero saber enquanto ele pressiona.
Por isso, aqui está meu POG para o amado onPress.
[code lang="actionscript"]package examples{
import flash.events.MouseEvent;
import mx.containers.Canvas;
public class PressMe extends Canvas {
private var somecanvas:Canvas= new Canvas();
public function PressMe() {
super();
addChild(somecanvas);
somecanvas.setStyle("backgroundColor", 0xFFFFFF);
somecanvas.width=100;
somecanvas.height=100;
somecanvas.addEventListener(MouseEvent.MOUSE_DOWN, start);
}
private function start(evt:MouseEvent):void{
somecanvas.startDrag();
somecanvas.addEventListener(MouseEvent.MOUSE_UP, stop);
}
private function stop(evt:MouseEvent):void{
somecanvas.removeEventListener(MouseEvent.MOUSE_UP, stop);
somecanvas.stopDrag();
}
}
}[/code]
