This is documented in the Lion AppKit release notes. https://developer.apple.com/library/mac/releasenotes/Cocoa/AppKitOlderNotes#10_7Scroller A subclass of NSScroller uses legacy scroller style by default. A subclass which is aware of the newer overlay style and _meets certain other conditions_ may override +isCompatibleWithOverlayScrollers to return YES. The docs for that method explain the other conditions, but it sounds like your subclass won't pass because you're overriding -mouseDown:. https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSScroller_Class/Reference/Reference.html#//apple_ref/doc/uid/20000340-SW40 Regards, Ken _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
