[news.eclipse.tools.gef] Using GEF without draw2d

[Eric Greene <eric@xxxxxxx>]

I want to create an RCP app using the opengl plugin. Some requirements 
for the app include having a palette of tools, that allow the user to 
add geometric primitives to the opengl canvas, as well as perform other 
edit operations. I like the GEF framework MVC architecture, and think it 
could be usefull. All the examples and tutorials of GEF assume Draw2d, 
and use GraphicalViewer, etc. So these are the questions:

1) Can i use GEF, and create my own GEF derived classes from abstract 
classes higher in the GEF class hierarchy?

2) How would the event system work with a opengl canvas and GEF?

2) Which classes would I need to implement?

3) Is this worth the effort or should I just use basic SWT/JFaces design?

4) Is there any tutorial on this, or do I need to study the design of 
draw2D based classes?
