The 10.6 document seems to imply that tapping isn't a gesture, so I'd assume you'd have to implement the NSResponder methods 'touches…WithEvent:' and use the event times to decide (a) if precisely 2 touches begin/end more or less simultaneously and (b) if a second 2-touch tap begins within a time interval after the 1st one [iOS defaults to 0.5 sec for this interval. Perhaps on the Mac you'd use something conditioned by the double-click time instead. I dunno.] and (c) if both 2-touch taps last less than some time interval [otherwise they'd represent a long press]. Something like that? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
