I should have probably said a little more about this.
At the time I separated cgWindow from the underlying
object-widget functionality, I added a few methods
to make working with the object-widget easier. In
particular, the PackageCommand method will package
an IDL command up into a cgWindow_Command object.
(This was the essential functionality of the old
cgWindow code.) Once you have the command object,
you simply add it to the window with either the
ReplaceCommand or AddCommand methods.

commandObj = windowObj -> PackageCommand('cgPlot', data)
windowObj -> AddCommand, commandObj

If your interface is resized, you determine what
size your graphics window should be, and you call
the Resize method with the new sizes.

windowObj -> Resize, event.x, event.y

Cheers,

David
