I am using BufferStrategy with 2 buffers to render off screen and then blast
the contents on to the screen and I am impressed with the simplicity of it and
its performance. However, there is a VERY serious problem with it, at least
the way I am using it. It seems that whenever the JFrame is resized something
is causing the screen to be cleared. The result is bad flickering or, even
worse, a totally blank screen.
I am using BufferStrategy in the technique in the JavaDoc as follows:
[code]
do {
do {
g2d = (Graphics2D)this.strategy.getDrawGraphics();
// Perform rendering here...
g2d.dispose();
} while (this.strategy.contentsRestored());
strategy.show();
} while (strategy.contentsLost());
[/code]
The clearing of the screen happens after any calls to strategy.show() and even
if I call it repeatedly after a resize event it seems that the screen will
clear after the last call. All that is required to restore the screen's
contents is to render again but I cannot work out how to trap this screen
clearing event and therefore know when to re-render.
Why is the screen clearing after the frame is resized? Is there a way to
prevent this, perhaps by using a different actual strategy for the
BufferStrategy? The screen clearing after resizing doesn't occur if I just
manually use a BufferedImage instead.
