使JFrame不重绘

Question

im trying not to repaint my window in Java. I have:

public void paint(Graphics g) {
        super.paint(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        ball.paint(g2d);

    }

and in main:

while (true) {
            game.move();
            game.repaint();
            Thread.sleep(10);
        }

my JFrame is window and I have tried window.setIgnoreRepaint(true); but there was no change. Could you give me a hand? Thank you :)

Answer 1

while (true) {
        game.move();
        game.repaint();
        Thread.sleep(10);
    }

must be replaced with

            Timer t=new Timer(10,new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    game.move();
                    game.repaint();
                }
            });
            t.start();

And override paintComponent() of content pane.

super.paint(g) repaints the window - you need to remove this line.

public void paint(Graphics g) {
        // super.paint(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        ball.paint(g2d);

    }
