menu

Hi,

I have an NSMenu that contains NSMenuItems with custom views. I want it so that when the alt button is pressed, the menu items would change part of their look (through their view). I found setAlternative in the NSMenuItem docs, however, in practice I could only get it to work with NSMenuItems without custom views. As soon as I set a custom view, all of the menu items would be displayed. Also, I tried getting keypress events while the menu was open. Due to the other run loop, NSApplication's sendEvent: doesn't receive events until after the menu is closed. Therefore, I can't just intercept the event coming in.

Does anyone know how I can get notified, whether through delegation or subclassing, of when the alt key is pressed when a menu is opened?

I am making my own NSMenu programatically and popping it up when a button is pressed. I create NsMenuItems and add them with the NSMenu method insertItem:atIndex:. For some reason whatever item is at position zero in the menu does not show up. Is this how the menu is supposed to work? >>> More

As docs say it's impossible to add two menu items to NSPopUpButton if they both have the same title. I was trying to add menu items to [popupButton menu], but with no luck.
