If or when Apple ever removes Carbon, I foresee APIs moving to new homes. It's not like the current system has two shared libraries (Carbon/ Cocoa) and when Carbon goes, all APIs go with it. In many cases, Carbon APIs are just wrappers over lower-level code. If there are key pieces of functionality that you can do in Carbon, but not Cocoa, definitely file enhancement requests to add those APIs to Cocoa. ___ Ricky A.

Sticking with NSEvent is better not because GetCurrentKeyModifiers() is Carbon, but because of the nature of GetCurrentKeyModifiers(). Please read the excellent comments in the header that I mentioned. The OP was vague on his goals/needs, so GetCurrentKeyModifiers() maybe appropriate.

modifier key query
Is there a way to know if a modifier key (shift, ctrl, option, cmd, etc) is pressed? Obviously, there's this: NSUInteger modifierFlags = [theEvent modifierFlags]; but what if you need to know this information independent of an NSEvent? Anyway to get it? So far I haven't seen anything encouraging in the docs. thanks, wes ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You don't get it independently of NSEvent, you get a specific event whenever the current set of modifiers changes, an event of type NSFlagsChanged. Given that you are informed with an event each time the modifiers change, I'm not sure why you want to know this information independent of an NSEvent.

Re: modifier key query
Given that you are informed with an event each time the modifiers change, I'm not sure why you want to know this information independent of an NSEvent. Mainly because I'd like to be able to control various animating behaviors via key modifiers but if the user isn't generating new mouse or key events, you can't tell if a modifier key has been pressed/released, which can make for awkward interface experiences with my current design. Clearly there are better ways to do things, I was just experimenting and curious. best, wes ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
