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.
> It would be good to have stackable events for our elements.

> Project: XAP
> Issue Type: Improvement
> Components: Macros, MCOs, Widgets, XML Dom / Parsing
> Reporter: Turyn, Michael
>
> I think >1 "onXXX" event attributes on an element should be allowed;:
> <aWidgetTag onMouseDown="mco:A.foo()"
> onMouseDown="mco:A.bar(...)" ..../>
> ---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.
