如何在java面板中显示图片~~面板代码如下

package actin;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;

public class TestPanel extends JFrame
{
JTabbedPane container;

public TestPanel ()
{
super("图片打印窗口");
init();
}
/**

* 界面组件初始化
*/
private void init(){
//定义界面大小
this.setSize(800, 600);
//定义界面出现在显示器中间
this.setLocationRelativeTo(null);
//定义界面右上角的x符号退出
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
//定义界面大小不可变
this.setResizable(false);
this.setName("Analyse");
//添加界面组件
setContainer();
//添加组件监听器
// addListener();
//定义界面可见,放测试方法里面了
// this.setVisible(true);
}

private void setContainer() {
//实例切换面板
container = new JTabbedPane();
//具体显示面板1
JPanel container1 = new JPanel();
//添加显示面板到切换面板
container.addTab("面板显示图片", container1);
//添加切换面板到界面
this.add(container);
}

/**
* @param args
*/
public static void main(String[] args) {
TestPanel test = new TestPanel();
test.setVisible(true);

}
}

Answer 1

private JPanel createContentPane(){
JPanel pane = new JPanel(new BorderLayout(0,8));
pane.setBorder(new EmptyBorder(12,36,12,72));
// ImageIcon icon = new ImageIcon(
// getClass().getResource("title.png"));
//"/com/tarena/elts/gui/title.png"));

pane.add(BorderLayout.NORTH,
new JLabel("-----------------连接服务器-----------------",
JLabel.CENTER ));

pane.add(BorderLayout.CENTER,
createMenuPane());

pane.add(BorderLayout.SOUTH,
createBtnPane());
return pane;
}

Answer 2

方法setContainer()中container1中追加label然后显示图片

追问

不会写~~~不明白 如何追加呀？求解

追答

ImageIcon Icon = new ImageIcon(你要显示的图像文件路径);
JLabel imageLabel = new JLabel(icon);
container1.add(imageLabel);

大概是这样的。你自己再看看

追问

private void setContainer() {
container = new JTabbedPane();
JPanel container1 = new JPanel();
container.addTab("面板显示图片", container1);
this.add(container);
ImageIcon Icon = new ImageIcon("D:/Program Files/Genuitec/MyEclipse8.6/Workspaces/Excel/WebRoot/01.jpeg");
JLabel imageLabel = new JLabel(Icon);
container1.add(imageLabel);

}
还是没有显示 求解
