That was exactly it. Thank you very much! Mike

I'm guessing the problem is that you are only calling setFrame: on subview 0, thereby increasing the total width of the subviews. You are assuming subview 1 will adjust by the same amount as you added/ subtracted from subview 0. But actually, adjustSubviews scales both subviews down so their total width is what it was before. You can see this by doing an NSLog *after* the call to adjustSubviews.What you need to do is adjust the width of *both* subviews -- add from one, subtract from the other -- maintaining constant total width.--Andy On Mar 11, 2009, at 2:17 PM, Mike Manzano wrote:Well, I just rewrote it, and it's doing exactly the same thing.

If you are performing active tracking, you may have to do so yourself. Try calling [window flushWindowIfNeeded] on your window at the end of your loop (inside the loop).What is the reason for your explicit tracking?You should be able to simply listen for mouseDragged, mouseDown, and mouseUp on your split view (if this is a custom sub-class).Jesper Storm Bache On Mar 10, 2009, at 2:51 PM, Mike Manzano wrote:Hi,I am tracking the mouse pointer to dynamically resize a splitter as aseparate drag handle is dragged.

During thistime, however, I can see the view sizing visually lag. When the drag finishes and the "Finally" block prints out, querying the view for itsframe displays what I believe to be the actual lagged dimensions. Can anyone tell me what's going on?
