Canvas Double Buffering - help!

[Guest]

Hi all, I need some double-buffering help...

I have created an applet, which has a paint() method. There is also a derived Canvas class I made ("PlotCanvas"). The applet draws two
instances of these, each with its own paint() method. So, I tried following the instructions here:

But I get problems in paint(), since calling getGraphics() returns NULL. Even when I check for NULL, and skip painting until
getGraphics() doesn't return NULL... it never doesn't return NULL. I can give more details if need be. This a common problem?


Thanks!
