I have a program that, instead of repainting the screen at intervals, will
draw to an offscreen buffer and then copy the buffer to the main viewport.
This works in the JDK Applet Runner.
However, when I try to run the applet in Netscape (and in Roaster's Applet
Runner), the screen does not get update automatically... the program is
running fine otherwise. You see, if I place a window in front of the
running applet and then remove the window, the applet will redraw
correctly, as if it had been updating all along.
Now, my question... is the fact that the buffering works in JDK a bug in
JDK or is the fact that it doesn't work in Netscape/Roaster a bug in those
programs?
In addition, is there another way to buffer/repaint the screen without that
annoying "flicker"?
Sorry for this being a little rambling and incoherent.... =)
Thanks,
- Tony
