Prevent NSScrollView from flashing its scroller

Question

I would like to prevent a subclass of NSScrollView from flashing its scroller.

I tried to override -[NSScrollView flashScrollers] with empty implementation, but it does not work.

Any suggestion?

If you hide the NSScrollView before setting the scroll position and show it again, it will prevent the scrollbars from flashing.

Here's a code sample:

[_scrollView setHidden:YES];
[[_scrollView contentView] scrollToPoint: NSMakePoint(0, scrollPosition)];
[_scrollView reflectScrolledClipView:[_scrollView contentView]];
[_scrollView setHidden:NO];
