Dear All,
I have a question described as below:
I created an NSImageView and put an image inside the view.
I would like to create a selection area (shaded rectangle) when user
drag on the image (similar to dragging mouse in Finder).
How can I do that? Use addTrackingRect in NSView?
Thank you very much for your help.
Yours,
Bill
