Usage

From source file:MultiBufferTest.java

public MultiBufferTest(int numBuffers, GraphicsDevice device) {
    try {/*from w  w  w . j a  va  2s . c  om*/
        GraphicsConfiguration gc = device.getDefaultConfiguration();
        mainFrame = new Frame(gc);
        mainFrame.setUndecorated(true);
        mainFrame.setIgnoreRepaint(true);
        device.setFullScreenWindow(mainFrame);
        if (device.isDisplayChangeSupported()) {
            chooseBestDisplayMode(device);
        }
        Rectangle bounds = mainFrame.getBounds();
        mainFrame.createBufferStrategy(numBuffers);
        BufferStrategy bufferStrategy = mainFrame.getBufferStrategy();
        for (float lag = 2000.0f; lag > 0.00000006f; lag = lag / 1.33f) {
            for (int i = 0; i < numBuffers; i++) {
                Graphics g = bufferStrategy.getDrawGraphics();
                if (!bufferStrategy.contentsLost()) {
                    g.setColor(COLORS[i]);
                    g.fillRect(0, 0, bounds.width, bounds.height);
                    bufferStrategy.show();
                    g.dispose();
                }
                try {
