The ScrollArea sources are in the 'gb.gui.base' component project in 
'/comp/src'.

A simpler example of its use is the ImageView control located in 'gb.form'.

You use the ScrollArea exactly like the DrawingArea, except that:

1) You must define the contents size with the ResizeContents() method.

2) You must take the vaue of ScrollX and ScrollY properties into account 
when drawing inside the Draw event handler (at least for things that 
must move with the scrollbars).

3) A ScrollArea has no "Cached" property. You must implement the Draw 
event handler.

4) You have a "Shadow" property if you want to draw nice shadows on 
borders where scrolling is possible.
