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 ?
/Rolf
