Thanks everyone for your help on this. I wanted to know if the
mouse was on the border area prior to the mouse down event to
determine if the mouse icon should change as the mouse hovers over
the border. Is there a way to do this without a mouseMoved event?
Thanks,

Hi All,
I was wondering if there is a straight forward away to know if the
mouse is on the border of a view? 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.
Thanks,
Mazen

The "border" of a view doesn't really exist - it's infinitely narrow.
What you really want is to detect that the mouse is inside the view
but within a pixel or two of the edge. That is easy to work out by
comparing the mouse point against the bounds to whatever degree of
precision you want (I'd suggest not making it too precise, as it
will be hard to hit - 4 pixels minimum is probably OK).

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?
