How do I make an NSMenu act as a pop-up menu without the use of
NSPopUpButton? I see there are class methods to make it pop up as a
contextual menu, but I need it to pop up as a pop-up menu like
NSPopUpButton magically does, so that one item in the menu can be
pre-selected.
I've searched the archives, and have already tried calling
_NSGetCarbonMenu() for use with PopUpMenuSelect(), but the function
is always returning NULL, and even if this did work and didn't use
undocumented methods, it still won't work in 64-bit.
To show a menu as if it were a popup menu, create an
NSPopUpButtonCell, call setMenu: on it, and then call [popupCell
performClickWithFrame: inView:].
The NSPopUpButtonCell can be entirely transient - you can create it
and destroy it in your mouseDown: method, for example.
