Thanks for your reply. I'm not so sure, though - I've tried overriding -inLiveResize to return NO no matter what, I've tried overriding -drawRect: and passing [self visibleRect] to super's -drawRect, and I've tried calling -display, -setNeedsDisplay: and -displayIfNeeded in various places, immediately upon resize, to try to force an entire redraw, but nothing has any effect - except, as I say, on the columns that are actually being resized. I wish I could find that thread which seemed to indicate some private view was used in the drawing during live resize, but I can't find it anywhere... Perhaps I did imagine it.
Thanks again, All the best, Keith --- On Thu, 6/25/09, Kyle Sluder <kyle.slu...@gmail.com> wrote: > From: Kyle Sluder <kyle.slu...@gmail.com> > Subject: Re: Recalculating NSTableView row sizes during a live column resize > To: "Keith Blount" <keithblo...@yahoo.com> > Cc: cocoa-dev@lists.apple.com > Date: Thursday, June 25, 2009, 8:10 PM > On Thu, Jun 25, 2009 at 11:10 AM, > Keith Blount<keithblo...@yahoo.com> > wrote: > > ...Except.
