Dear Jay,
If you want the font context to be guaranteed "live" at all
times, you could try the following:
1. create a JFrame
2. call the JFrame's addNotify() method to create its peer.
3. call getGraphics() on the JFrame.
4. use the FontRenderContext on this GC.
That should create a FontRenderContext that will be working all
the time. I don't know how long the GC that comes in through the
"paint(" method is "live", so I've been using external GCs from Frame
classes. Moreover I usually do some calculations before the "paint(" is
executed, and using an external GC solves that problem too.
Hope this helps.
Sincerely,
Thorn Green
