I am a beginner in the field of Cocoa, so please forgive me if this is a RTFM style question, however i've did a good amount of googling before writing here, so even a pointer to the appropriate place in the manual is appreciated. I've defined a simple form with an NSImageView and an NSButton. When the button is pressed the program should grab the contents of the screen, and place it in the NSImageView. For further processing, the NSImageview is just a POC control.
