Hi everybody,

Here is another improvement in appearance: NSScroller.
Fist patch changes drawing of knob slot of NSScroller (stiplled
instead of solid). Second one is updates NSBrowser according to
NSScroller's changes.

I didn't apply this patch, mostly because I kind of like the solid
background, although I could be convined otherwise. Does anyone else
have a preference?

  Tastes differ... I like OPENSTEP look of NSScroller.

I think we should stick to policy of having a NeXTstep look ... and use
NSInterfaceStyle where people want alternatives.  So a patch to support
an interface style which gives a stippled scroller background ought to
be admissable IMO.

Working on NSScroller, I've noticed that coordinate system of the
gnustep-gui and gnustep-back is not the same. NSScroller's knob slot
is drawing with number of rectangles using:

Isn't it because the scroller is a flipped view?

  Yes, thanks. But I didn't quite understand why it is flipped...

To be compatible with OPENSTEP ... where this class is flipped.
I remember this from *way* back ... and just checked up that it is
still flipped in MacOS-X.
Really I think that this should be documented in the source code.
