Menu fading

[Greg Brown <gk...@mac.com>]

BTW, the menu fading issue Todd identified is a pain to fix.  :-)  We  
can't just fade a menu whenever it closes, because that breaks the UE  
when a menu is opened from a menu bar and the user mouses over another  
menu bar item. In that case, we want to close the menu immediately.  
However, in all other cases we want it to fade.

Unfortunately, we don't currently have any way to distinguish between  
these two cases. I am currently thinking about the best way to  
introduce support for this, but suggestions are welcome.

FYI, my current plan is to add an "immediate" flag to  
MenuPopup#close() and add a MenuPopupStateListener interface that  
includes preview, veto, and close events that include this argument.  
That will allow the menu skin to decide whether or not to run the  
transition. When a menu popup is closed as a result of the menu bar  
activating another menu, close(true) will be called, and the menu  
won't fade. In all other cases, close(false) will be called, and the  
menu (and all sub-menus) will fade out.

If anyone has any comments or other suggestions, please let me know.
