[jira] Commented: (XAP-317) It would be good to have stackable events for our elements.

Trevor Oldak commented on XAP-317:
----------------------------------

I think the best way to do this would be to have semicolon-delimited event handlers. so instead of:
<aWidgetTag onMouseDown="mco:A.foo()" onMouseDown="mco:A.bar(...)" ..../> 

You say
<aWidgetTag onMouseDown="mco:A.foo();mco:A.bar(...)" ..../>

That way, you don't have to create new functions for appending more event handlers to the same event.

> ---on the mouse down event they would be called in the order declared; this would be good for cutting-and-pasting functionality modularised as MCOs and Macros.
> This is one of the best things about the Dojo connect() mechanism, and also seems to be in place for Yahoo UI dragging events.
