实现双缓冲画图

Question

public void paint(Graphics g)
{
        Image imgBuffer = this.createImage(this.getWidth(),this.getHeight());
        Graphics gimg=imgBuffer.getGraphics();
gimg.drawString("test",10,10);
gimg.dispose();
g.drawImage(imgBuffer,0,0,null);
} 
所有的绘制工作都在imgBuffer上完成，最后用drawImage把它画出来

Answer 1

楼上的imgBuffer应该说明成BufferedImage imgBuffer
