I'm trying to use an NSTextView to display the output of a shell
script, but when my script outputs too much data, too quickly (on the
order of a dozen lines nearly simultaneously), my app gives up with a
pinwheel. I'm using an NSPipe to get the data,
readInBackgroundAndNotify to know when to put it in my view, and
[[[myTextView] textStorage] appendAttributedString:] to do the actual
view updating. After a while, when my view starts to contain thousands
of lines or so, attempting to do any scrolling causes a pinwheel for
some length of time. Any ideas on how I could do this better? My only
requirements are that it updates in near realtime, can support near-
unlimited butter size, and supports attributed strings, so I can color
specific keywords.
Thanks in advance,
Steven
