NSDrawer prevent from resizing

Is there a way to prevent a NSDrawer from being resized? I've 开发者_运维知识库tried setting the Min and Max content size to the same value and no luck.

Set up an NSDrawer delegate which implements drawerWillResizeContents:toSize:. If the method just returns [sender contentSize], the drawer's content size won't change.

If that doesn't prevent the overall drawer size from changing, your delegate may also need to implement windowWillResize:toSize:, as mentioned in the above documentation link for drawerWillResizeContents:.
