[MACTCL] Multi-column menus in Cocoa Tk

[Tom G. <go...@cg...>]

Are multi-column menus and colored backgrounds for menu entries 
supported in Cocoa Aqua Tk (8.5.8 backport or 8.6b1)?  I have tried with 
the 8.5.8 backport of Cocoa Aqua Tk but neither of these features work.  
Both features do work in the Carbon Aqua Tk in 8.5.6 if the following 
magic is used before creating the menus

    set ::tk::mac::useCustomMDEF 1

Thanks.

no, only features directly supported by NSMenuItem (images, colored
text foreground, fonts etc) are supported. Anything else would require
a custom NSView in the NSMenuItem:
    http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/MenuList/Articles/ViewsInMenuItems.htm
it might be worth investigating whether Tk could provide a facility to
allow extensions to specify such custom views...
