Re: custom menu for NSPopUpButton

Hi Kurt,

In Leopard, you would do this by writing a custom view for your
palette and adding it to a menu item via the new API -[NSMenuItem
setView:].

http://developer.apple.com/releasenotes/Cocoa/AppKit.html#NSMenu

There isn't support for menu customization of this scope prior to
Leopard.  On the other hand, you could do this on prior system
versions by not using a menu.  You could make a custom view that
stamps out a pop up for its drawing, and handles mouse clicks (and
keyboard nav!) itself by popping up a window with your palette.  This
is definitely work, but it's doable.
