"Change Set: ResizingGrid Date: 28 May 2005 Author: Ross Boylan
Make a TwoWayScrollPane in which the material inside the TransformMorph will still be resized to fit vertically into the outer window.
The goal was to do a TableLayout inside the transform so that no vertical scrolling was necessary.
The following code initializes a subclass of SystemWindow to contain the such a ScrollPane. myPane _ RBTwoWayScrollPane new. myPane layoutPolicy: RBScrollLayout new. myPane scroller layoutPolicy: TableLayout new; listDirection: #topToBottom; wrapDirection: #leftToRight; enableDragNDrop; vResizing: #spaceFill; color: Color transparent. self addMorph: myPane frame: (0 @ 0 corner: 1 @ 1) "!
