- Thanks to everybody who replied to my previous question on
- ScrollViews (why I was losing subviews during scrolling).
-
- Another question: Scrolling seems to be incredibly slow.
- How does one speed it up ? Are there standard ways to
- scroll quickly (and still have dynamic drawing) ?
-
- The best idea I have (at the moment) is to implement
- a compositing operation (keep a copy of the entire DocView
- and copy it in). This seems somewhat baroque (and wasteful
- of memory) though.
-
- What am I missing ?
