Thank you for your response.

I tried this. I put a breakpoint in tile, and tile is never called during expand or collapse. Although tile is called at other times, like when the window is opened.

Since tile is never called it does not appear that this will have any effect.

Any ideas?


Well, again -- it really depends on where your performance problem lies; I strongly suggest sampling to find out what is slow. tile will be called in various locations from various operations. If the problem is the frameSize changing, you can override setFrameSize: and do a similar operation -- but, first thing first: sample (using 'sample' or Shark)! If you get some samples of what is slow post them here.
