Question is how to draw the rectangle showing what part is to be captured
(the captureRect).
It is too large to be drawn from within the graphView. But where should it
be done then? I have nothing but an NSWindow and the two graph views. So
should it be done from the NSWindow? But then I would have to subclass the
NSWindow(?)
How about a borderless, transparent window floating above the
capture area whose content view fills with a translucent color (with
an alpha component of 0.2, for example)?
Another question: is it necessary to do all the drawing in the drawRect
method?
No, but all your drawing code gets initiated by -drawRect: ... check
out the Sketch example in your /Developer/Examples folder. From within
-drawRect: you can figure out what needs to be drawn and call other
methods like "-drawMyGraphicInThisRect:", etc. See the documentation
(search for Cocoa Drawing) to learn more.
