Actually the snippet creates an anonymous subclass of 
EmbeddedSwingComposite. The subclass implements only the 
createSwingComponent() method. That's basically how it was intended to 
be used.

1 and 2 sound fine for now. See advice above for creating a subclass of 
EmbeddedSwingComposite (in your own folder) instead of 3. Implement the 
createSwingComponent() method to create your NetCanvas.

I would focus on getting the original code working in your project 
first. But you definitely should take a look at his suggestions, 
especially if you are noticing problems.

We are working on getting the project approved and moving it forward. If 
all goes well, there should be an updated CVS code repository available 
in the future. Until then, it's a bit of pain, sorry. (And, there are no 
guarantees that the programming interfaces will stay the same.)

It completely depends on what you are doing. Basically, you just need to 
try to make your AWT/Swing API calls on the AWT event thread and SWT API 
calls on the SWT event thread.
