So before implementing a special NSSplitView as part of SWK, I am looking for the best method to achieve the same using standard components. Any hints and/or sample code are welcome. Your benefit will be a nice Browser and Online Help system for GNUstep...
Just resize (and reposition) the subviews involved as appropriate and then invoke the NSSplitView's -adjustSubviews method. The latter call apparently is necessary (at least on OS X) so that the AppKit redraws the divider. Note that -adjustSubviews will not change the size and positions of the subviews only if they already fill the split view's frame with the necessary space between the subviews (as determined by -dividerThickness). Also recall that NSSplitView uses a flipped coordinate system, i.e., the origin is at the top left corner. Wolfgang
