How can I automatically hide an NSScroller in Lion?

Question

I have an NSScroller that is used to scroll some complete custom view of mine. With [scroller setScrollerStyle:[NSScroller preferredScrollerStyle]] I get the correct style of the scroller. Now when the scroller has NSScrollerStyleOverlay , I assumed it will automatically hide when it is not used. Like it does when using a standard NSScrollView. But it doesn't. It's always visible.

Is there a suggested way to hide the scrollers automatically? Or do I have to do that manual with timers etc?

Answer 1

See What's New in Mac OS X 10.7 — Overlay Scrollbars

Under Compatibility Notes , you may be probably hitting the 3rd case: "Any NSScroller that is not managed by an NSScrollView". Or possibly you have an "external pointing device" that doesn't fully support overlay scrollers?

Answer 2

Choose Your scroller and go to "Attributes inspector" and check checkbox "Automatically Hide Scroller". That should do it.

Answer 3

I ended up redesigning my view's so they fit in a UIScrollView. So I worked around this problem.
