Re: Delaying mouseDragged event

Following the advice of "joar" from my previous question, I have tried to implement code to check for a pixel difference between a "mouseDown" and a "mouseDragged" to know if I should start a drag and drop. However, I am clueless as to how I would go about telling the event system "Ok, I am not really interested in this mouseDragged, but If the user move the mouse another couple pixels go ahead and send me one again."

There is no way to delay -mouseDragged: from being called. What you probably want to do instead is enable periodic events, have the view listen for periodic events, and then do whatever you were doing in -mouseDragged: if a periodic event reports that the mouse button is still down & the mouse has moved a certain distance away from the point in the original event. And don't forget to stop the periodic events when the mouse button is back up. See <http://developer.apple.com/documentation/Cocoa/Conceptual/ EventOverview/Concepts/PeriodicEvents.html> for more information.
