Flex 3: How do I remove a Component Using a Button in the Component
I'd like to use a button within a component to remove it. So, you click it and the component is gone. But, I haven't figured out how you reference the component from within the component. What should I put in click=""?
My component: popCanvas
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Panel width="200" height="200" title="hello"
click="remove=">
</mx:Panel>
</mx:Canvas>
In the main app:
var popCanvas:PopCanvas= new PopCanvas;
popCanvas.x = 20;
popCanvas.y = 30;
this.addChild(popCanvas);

Okay,
This is what I came up with:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
public function removeMe(event:MouseEvent):void {
this.removeChild(event.currentTarget as DisplayObject);
}
]]>
</mx:Script>
<mx:Panel width="400" height="300" title="hello" click="removeMe(event)">
</mx:Panel>
</mx:Canvas>
So, I used the event's currentTarget to reference the component in order to remove it. If someone clicks anywhere on the component it's removed.
Thanks.
