onMouseEnter / onMouseLeave x-browser support

[Sam Foster]

IE implements the onmouseenter/leave pair of events which do what most people *mean* when they register onmouseover/out - fire only when the mouse enters that element, and leaves it (vs the extra events that are generated by mouseover/out on child elements). Mouseenter/leave events do not bubble/propagate.

MSDN link: ​http://msdn2.microsoft.com/en-us/library/ms536945.aspx (according to google, its down for me today) Apparently, the same events are available in Mono, and possibly elsewhere.

It would be great to be able to register handlers for these events in dojo - across dojo's supported browsers. Either in event.js, and/or in dijit/_Templated.js

This is already implemented inside the dnd code, fwiw. Should just be a matter of moving it and exposing it?

Possible code at ​http://blog.blowery.org/2007/06/04/monday-the-4th/

It's my code and I'd willingly donate it to Dojo. :)

(In [10592]) convert widgets to use onmouseenter and onmouseleave as apropriate. Refs #4307

[alex]

(In [10593]) add support for onmouseenter and onmouseleave to all DOM Nodes which are dojo.connect()-ed to. Fixes #4307

[alex]

(In [10594]) add onmouseenter and onmouseleave to the shortcuts provided by NodeList?. Refs #4307

[alex]

ben: went with your solution (roughly). Thanks for pointing me at it.

[10592] causes ComboBox? to throw DOM exceptions in FF2. Seems related to _FormWidget mouse handling.

Refer to ​http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/form/test_ComboBox.html

[haysmark]

To reproduce, just move your mouse over a ComboBox? and check the error log.

This IS a firefux bug and a regression of ​http://trac.dojotoolkit.org/ticket/1807

The simplest way to handle the error is to use a try, catch statement.

(In [10701]) Disable onmouseenter and onmouseout until #4307 is fixed on FF. (Refs #4307.)

[alex]

(In [10981]) re-enable onMouseEnter/onMouseLeave, but this time with some smarts about FF's bugs. Fixes #4307

fyi.
