That seems risky, especially for methods that access class variables 
belonging to SCWindow and such.

GUIWindow.viewSourceClass = SCWindow;
GUIWindow.allWindows

GUIWindow.viewSourceClass = JSCWindow;
GUIWindow.allWindows

I don't want to have to track down those bugs!

It's a gui platform, you should use one at a time.

I'm open to whatever naming convention people prefer.

Not sure I follow you. The thought was to create a layer between the 
user and the gui objects (was it cx or blackrain who mentioned it 
first?). The layer's interface would be exactly the same across all gui 
platforms so there's only one interface to learn and code doesn't have 
to be rewritten. For SCView/JSCView not much problem, but the SCUM 
interface is quite different.

My main objective is, I want the guis in my library to work in Linux or 
Windows without maintaining multiple versions (that requires the cx 
guis to work too).

Marije mentioned (correctly) that scum-specific functionality should 
not be taken away. This approach works for that -- you can always use 
the gui classes directly, but you have a way to write cross-platform if 
you want.

Any other comments/criticism before I slog through the ^this methods 
(not looking forward to it!).
