I would install a window handler for _kEventMouseDown ( but you can also pick other other mouse events - see kEventClassMouse in Tlbx CarbonEvents.incl ) to get a click and then in the handler check the coordinates of the mouse click to see if it is within the content region. Code has been posted on this topic many times and there is a Carbon Event example that should enable you to develop your own code.
