Scroller's background at NSTableView

Question

How can I change background color of scroller at NSTableView? For example I've made black background color of my TableView and got white scroller, I want ClearColor or Black color of Scroller's background. How can I make it?

Answer 1

You'll need to subclass NSScroller and override its -(void)drawRect: method

- (void)drawRect:(NSRect)dirtyRect
{
    // the only line is required
    [self drawKnob];
}
