Alert and mouse & key events - actionscript-3

Question

When showing an alert box with mx.controls.Alert.show() and clicking it's buttons with the mouse (or Enter key) or clicking anywhere, these events are passed to the parent window as well, eventually triggering buttons there etc.
Is there a straight forward way to prevent this, like setting an attribute of the alert instance?

Answer 1

If you set the closeHandler parameter in show() you can then call event.stopPropagation() to prevent the event from being processed on subsequent nodes.
Code would look something like this:
Alert.show("Message", "Title", Alert.OK, parent, onClose);
function onClose(event:CloseEvent):void
{
event.stopPropagation();
// Do close stuff here
}

Added example for Flex 4.6, in Flash Builder 4.6:

<!-- Place non-visual elements (e.g., services, value objects) here -->

<fx:Script>
<![CDATA[
