Hi, all:

	I did something like this for our Knowledge Base. Basically,
for us, if you send a message to an Object like "display", it will
call the appropriate IV function to map the appropriate window.

	However, you must have "Session* session" as a global variable
to make the Styles and Backgrounds uniform for all windows.

	Here a brief outline of what I have in mind:

	Class MyClass : public MonoGlyph {
	public:
		MyClass (Raster*);
        }

	put MyClass into Scrollable.

	hehe, I wrote Scrollable, so I use it. :) :) :)

	have a funtion like:

	void display_image(const char* name) {
	     Raster* r = Raster::load(name);
	     MyClass m = new MyClass(r);

	     ApplicationWindow a = new ApplicationWindow(m):

	     a->map();
	     session->run();  // session is a global variable.
	}.

	I hope this helps, :)
