In fact, since there isn’t a handy-dandy method or property on any of the classes in question to just do it, I’m beginning to think that’s the case.

Still I have lots of lovely animations in XCode to make up for it so all is not lost! I’m giving up and it’s too much of a time-sync to muck around with it as I have more pressing things that need doing.

In other words, your text view will act like a peephole into a bigger page. That is what NSTextContainer is for. I think the references I gave to you for text handling in general will lead you to the relevant documentation.

An NSLayoutManager <https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSLayoutManager_Class/index.html#//apple_ref/occ/cl/NSLayoutManager> uses NSTextContainer to determine where to break lines, lay out portions of text, and so on. An NSTextContainerobject normally defines rectangular regions, but you can define exclusion paths inside the text container to create regions where text does not flow. You can also subclass to create text containers with nonrectangular regions, such as circular regions, regions with holes in them, or regions that flow alongside graphics."
