Here's my updated code:
private var moduleloader:ModuleLoader;
private var unload_button:Button;
private var vbox:VBox;
private var _aChildren:Array=[];
private function unloadclick(event:Event):void
{
var iIndexClicked:int = parseInt(event.target.id);
modulestile.removeChild(_aChildren[iIndexClicked]);
*error* modulestile.removeChild(event.target); *error*
}
public function AddColumnGraphPanel():void
{
var iNewIndex:int = _aChildren.length;
vbox = new VBox();
modulestile.addChild(vbox);
moduleloader = new ModuleLoader();
moduleloader.url = "test.swf";
_aChildren[iNewIndex] = vbox.addChild(moduleloader);
unload_button = new Button();
unload_button.id = String(iNewIndex);
unload_button.label = "unload";
unload_button.addEventListener(MouseEvent.CLICK, unloadclick);
vbox.addChild(unload_button);
}
<mx:Tile id="modulestile" direction="horizontal">
</mx:Tile>
I have the following error in the script:
1118: Implicit coercion of a value with static type Object to a
possibly unrelated type flash.display:DisplayObject.
Thanks again :)
