Hi Kyle,
I already have the model objects being backed by individual NSTextContainers
which then adopt the text view when they need to (using setTextView:). I was
just wondering if there are any recommendations how to conceptually handle code
folding, especially as I have line numbering. So, should I just add some
functionality (markers and mouse handling) to my NSRulerView subclass, and then
detect from the text where to draw disclosure triangles, and somehow fix-up the
line numbers? Then what to do with the text that is collapsed? One idea I had
would be to put the text that is collapsed in to a text attachment and replace
the text then by the attachment with an appropriate icon or indicator.
Does that all seem like a sensible approach?
Cheers,
Martin
