THIS RESPONSE DOES NOT WORK!!
Object carrying data about a user action, for example mouse clicks or keyboard presses.
Anybody know how to send a fake mouseUp event to a window or view?
I would check out this NSEvent class method.
int type=NSLeftMouseUp; // for a left mouse up event type int windowNumber=[windowToSendEventTo windowNumber];
id fakeMouseUpEvent=[NSEvent mouseEventWithType:type location:NSMakePoint(xValue, yValue) modifierFlags:nil timestamp:nil windowNumber:windowNumber context:nil eventNumber:nil clickCount:1 pressure:nil];
// On NSEvent +(NSEvent *)mouseEventWithType:(NSEventType)type location:(NSPoint)location modifierFlags:(unsigned int)flags timestamp:(NSTimeInterval)time windowNumber:(int)windowNum context:(NSGraphicsContext *)context eventNumber:(int)eventNumber clickCount:(int)clickNumber pressure:(float)pressure
If you want to watch all the events in your program, use NSTraceEvents.
See http://developer.apple.com/technotes/tn2004/tn2124.html for lots of cool tricks.
Watching events go by can be very informative.
To bypass event-handling and forward it to the NSApp’s delegate (I find this very useful in fullscreen games), make a custom subclass of NSApplication (ensuring that the Principal Class is your new subclass), and implement this method:
Of course, this assumes your delegate responds to shouldHandleEvents and handleEvent:. Going back to the fullscreen game example, this allows for one to have a Cocoa main menu and have the delegate (controller) handle the events appropriately, thus allowing true MVC. This can also allow for the same controller handle a windowed game, too. -[[RossDude
How to watch all the mouse events of the system? (NSTraceEvent is about one perticualr application). —- Google for CGEventTapCreate.

NSEvent timestamp is in time since system startup. NSDate doesn’t give a convenient utility to get that, and it’s not easy to find. After much digging I found this in an old cocoa-dev mailing list post:
#import <mach/mach_time.h> #define SKWTimestamp() (((double)mach_absolute_time()) * 1.0e-09)
