Thanks Gordon,
That worked. One other question regarding Sprite Drag and Drop.
Situation: Have a box drawn by the Shape Class which is in a Sprite.
I have the following code:
-------- Draw Rectangle ------------------------------------------
private function draw (name:String) {
if (w > 0 && h > 0) {
var sprite:Sprite = new Sprite();
sprite.name = name;
trace("name= " + name);
addChild(sprite);
var child:Shape = new Shape();
child.graphics.beginFill(0xffffff);
child.graphics.lineStyle(.5, 0x000000);
child.graphics.drawRect(0, 0, w, h);
child.graphics.endFill();
sprite.addChild(child);
sprite.addEventListener(MouseEvent.MOUSE_DOWN, dragObject);
}
}
----------- dragObject -----------------------------------------------
private function dragObject(event:MouseEvent)
{
if (event.target.name == "obj"){
var
dragInitiator:UIComponent=UIComponent(event.currentTarget);
var ds:DragSource = new DragSource();
ds.addData("name","format");
var canvasProxy:Sprite = new Sprite();
canvasProxy.width=30;
canvasProxy.height=30;
DragManager.doDrag(dragInitiator, ds, event);
}
}
----------------------------------------------------------------
When I try to drag this object, I get the following Error:
Type Coercion failed: cannot convert flash.display::[EMAIL PROTECTED] to
mx.core.UIComponent
If I don't cast the sprite to the UIComponent, I still get the same
error. It seems that the DragManager likes UIComponent types.
What would be a solution do you think.
Cheers,
Tim
