For my fullscreen app, I want to hide the cursor after a few seconds if it's not moved, like the fullscreen mode in QuickTime or iTunes. Presumably I'm looking to call [NSCursor setHiddenUntilMouseMoves:YES], but how do I know when to call it?
Presumably I'm looking for the same as Hide mouse cursor after an idle time but on the Mac. I couldn't find a way to get similar a "idle time". (Plus, I probably don't care about keyboard events, just mouse movement.)
You can get the time the cursor (and if you want also the keyboard) has been idle using:
CGEventSourceSecondsSinceLastEventType(kCGEventSourceStateCombinedSessionState, kCGEventMouseMoved)
Swift 3 code:
CGEventSource.secondsSinceLastEventType(CGEventSourceStateID.combinedSessionState, eventType: CGEventType.mouseMoved)
See also http://developer.apple.com/library/mac/#documentation/Carbon/Reference/QuartzEventServicesRef/Reference/reference.html. You're probably going to have to poll this function every couple of seconds, and you should assume the user moved the cursor if the time returned has decreased.
