/**
* Panel背景图片
* @version 2012-2-25
*/
public class BackgroundImage4Panel extends javax.swing.JFrame {
/**
* serialVersionId
*/
private static final long serialVersionUID = 1L;
/** Creates new form NewJFrame */
public BackgroundImage4Panel() {
getContentPane().add(new JPanel() {
/**
* serialVersionId
*/
private static final long serialVersionUID = -1183754274585001429L;
protected void paintComponent(Graphics g) {
super.paintComponent(g);
try {
g.drawImage(ImageIO.read(new File("C:\\image.png")), 0, 0, null);
} catch (IOException e) {
e.printStackTrace();
}
g.drawString("HelloWorld", 20, 20);
}
});
setSize(800, 600);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
/**
* 测试入口
* @param args 参数列表
*/
public static void main(String[] args) {
new BackgroundImage4Panel().setVisible(true);
}
}
重写paintComponent()方法即可 --------------------编程问答-------------------- Panel panel = new Panel() {
public void paint(Graphics g) {
g.drawImage(new ImageIcon("图片路径").getImage(), 0, 0, this);
}
}; --------------------编程问答-------------------- 噔噔噔,高手现身！！
