Hi
Currently in the process of converting a as3 project over to using
signals. Can someone help me with converting 'hasEventListener'?
//CODE START
downSignal=new
NativeSignal(this,MouseEvent.MOUSE_DOWN,MouseEvent);
if (this.hasEventListener(MouseEvent.MOUSE_DOWN) == false)
//would this be equivalent to?
if (downSignal.hasOwnProperty(MouseEvent.MOUSE_DOWN) == false)

You could use the numListeners property. Ie
if (downSignal.numListeners > 0) ...
