Thnaks!
That works. Now I have the NSImageview inside the NSScrollview. But how do I scroll
the image programatically ? I can get the instance pointer to the NSScroller's and set their
position using [scroller setFloatValue] method. This moves the scroller knobs, but nothing
happens to the image. I guess there must be some "update" method in NSImageView or
NSScrollView that will force them to re-read the scroller position, but I haven't found any -
except NSScrollView's reflectScrolledClipView which isn't right.
