I know how to detect if the mouse enters a view area by using NSTrackingArea - but how can I tell if the mouse is on a border? I would like to replicate iCal's behavior where a user can modify an event on the calendar by clicking on the edge of the appt. rectangle and dragging it.
In your mouseDown: method, compare the coordinates against the edges of the view's bounds.
Or is there a reason you need to know before the mouse-down occurs?
