NSSplitView - Preserve subview width on window resize

Question

I have an NSSplitView covering all of my window.

The NSSplitView contains two (vertical) subviews, one next to the other.

When the user resizes the window, I want the one on the left to remain intact. How is that doable?

P.S. Not the AutoLayout-way.

Implement window delegate.

- windowWillResize:toSize: in this method save the width of the one on the left

- windowDidResize:in this method restore the width of the one on the left
