I have an NSScrollView in which I wish to display several NSTextViews as shown below. (Much like here and here). I am adding all the different NSTextViews to an NSView using addSubView(), and then assigning the resulting view as the NSScrollView's documentView. This is working just fine. However, the NSScrollView does not scroll properly. When I run the app, I can scroll up and the NSScrollView will push up and back according to its elasticity, but I cannot scroll down. Sometimes, however, and I'm not entirely sure under what circumstances, I can scroll down. I think it has to do with whether I have focused the NSScrollView or one of the various NSTextViews, but I'm not sure. And, to make matters worse, when I have managed to scroll down to the bottom, I start to have the opposite problem: I can push the NSScrollView down, but not up.
I think this issue has something to do with the fact that I have subclassed NSScrollView. When I built this same setup using an NSScrollView as provided by IB, everything is fine. However, when I subclass NSScrollView in order to make positioning the NSTextViews easier, the scrolling functionality becomes all whacky. Can anyone point out why subclassing NSScrollView makes this happen and what I can do about it?
