I've got a subclass NSArrayController whose contents are displayed in
a table via bindings. There are several types of objects in this list
differentiated by various criteria. I'd like to let my users filter
that list and show only the type (or types) that they want.
My first attempt was to use my subclass and overwrite
arrangedObjects: and filter there. However, because the list of
objects is rather long, this resulted in poor redraw performance and
jerkiness during scrolling.
For various reasons (mostly performance and stability), I'd like to
keep all the objects in the array and simply filter them. Is there a
way to do this that I'm missing?
Thanks!
August
