Alex, thanks for your two posts and for taking the time to look at the original source code. Some comments:
Re: Integer being final. Actually, I remembered that...and then forgot. Tired? Clueless? You decide. I'm going to fold your observations into a new test program to see what happens; thanks. Re: subclassing: Unless I'm missing something, I still want to subclass PCanvas because the class adds another method, updateEdge, which gets called within the drag event handler. Anyway, I'll post again when I have something to report.
