The issue is that I really need a rect. Getting the actual image of
what is selected will tell me the width and height of the rect, but
not the x and y.
So, you're after the origin of the rect in addition to the dimensions?
Since IKImageView inherits from NSResponder, you can capture the mouse
coordinates in the -mouseDown: event and then again using -
mouseDragged:. Off the cuff, you'll then need to set the origin to the
minimum x value and minimum y value of the two points and set the size
to the max x-min x and max y-min y. (There's a good example of this in
Hillegass, Cocoa Programming for Mac OS X, 2nd ed if you have it handy.)
All that being said, I have to ask what functionality you are using
from IKImageView that you couldn't get from NSImageView? The above
would apply to NSImageView, too, but you wouldn't be including all the
IK goodness of IKImageView such as editing and NSImageView is
supported on more than just Leopard. Just a thought.
