Examples of java.awt.image.BufferStrategy

java.awt.image.BufferStrategy
k the capabilities of the GraphicsConfiguration ... // Create our component Window w = new Window(gc); // Show our window w.setVisible(true); // Create a general double-buffering strategy w.createBufferStrategy(2); BufferStrategy strategy = w.getBufferStrategy(); // Main loop while (!done) { // Prepare for rendering the next frame // ... // Render single frame do { // The following loop ensures that the contents of the drawing buffer // are consistent in case the underlying surface was recreated do { // Get a new graphics context every time through the loop // to make sure the strategy is validated Graphics graphics = strategy.getDrawGraphics(); // Render to graphics // ... // Dispose the graphics graphics.dispose(); // Repeat the rendering if the drawing buffer contents // were restored } while (strategy.contentsRestored()); // Display the buffer strategy.show(); // Repeat the rendering if the drawing buffer was lost } while (strategy.contentsLost()); } // Dispose the window w.setVisible(false); w.dispose(); @see java.awt.Component @see java.awt.GraphicsConfiguration @see VolatileImage @author Michael Martak @since 1.4
