[tor-commits] [arm/master] Rewrite GraphPanel's draw() method
commit fce787d6ff798dc826669dcbf810a14e9518f918
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>
Date: Wed Mar 18 09:15:32 2015 -0700
Rewrite GraphPanel's draw() method
Few months ago I was amid a rewrite of our GraphPanel. Last section left was
its draw() method which was a tangled mess. Said mess is now untangled.
I'm still not completely happy with it. For starters it doesn't have decent
thread safety if attributes are modified in the middle of redrawing but
definitely better than where we were at.
