Use Interface Builder's Layout->Make Subviews Of->Scroll View menu item.
When you programmatically create the scroll view, you need to make the
scroll view a sub view of some other view or the scroll view can never
be displayed.

Hi,
I have a wide jpeg NSImage in a NSImageView that is much narrower. I
need to programatically "slide" the jpeg horizontally inside the
NSImageView, pixel by pixel. NSImageView does not seem to have any
methods for positioning the NSImage inside itself (except for
left/right/center). I
think the solution is to place the NSImageView inside a NSScrollView,
turn off its sliders, and use NSScrollView methods for sliding the
jpeg back and forth. Am I correct ? I did not find NSScrollView on the
palettes pane of IB so I guess it has to be created programatically.
When the following code is run the entire NSImageView (imgSlider) just
"vanishes".
NSScrollView *scrollview = [[NSScrollView alloc]
initWithFrame:[imgSliding frame]];
[scrollview setDocumentView:imgSliding];
What's wrong ?
