After digging through the docs for an hour, I am sufficiently aggravated
to risk a flame over a trivial question -
How do I get the current system time in Cocoa?
I want to copy functionality in an old Mac OS application for handing
mouse events. The function I used timed how long the user held down the
mouse button - less than a specified interval and the event was treated
as a single click, and signaled a possible object selection - longer
than that interval and the mouse motion was tracked to control
interactive rotation. The use of NSTimer would seem to introduce
unneeded complexities for this simple task.
I would prefer to use methods in NSEvent to handle this subtlety, but at
this point my reading of the docs has not enlightened me as to how to do
this. I would appreciate any advice on either of these approaches to
handling the problem.
Thanks in advance,
Randy
