我想从src文件夹实现一个200 * 200图片到我的JTabbed Pane布局。如何将图片添加到JTabbedPane - 空面板布局上?
我的问题是什么都没有显示 - 没有错误没有例外,也没有图片。
我不认为我必须声明目录并将其设置为私有,因为它已经包含在src文件夹中。
import java.awt.*;
import javax.swing.*;
import java.awt.event.KeyEvent;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.JFrame;
public class Example1
extends JFrame
{
private JTabbedPane tabbedPane;
private JPanel panel1;
public Example1()
{
// NOTE: to reduce the amount of code in this example, it uses
// panels with a NULL layout. This is NOT suitable for
// production code since it may not display correctly for
// a look-and-feel.
setTitle("Program");
setSize(800, 400);
setBackground(Color.gray);
JPanel topPanel = new JPanel();
topPanel.setLayout(new BorderLayout());
getContentPane().add(topPanel);
// Create the tab pages
createPage1();
// Create a tabbed pane
tabbedPane = new JTabbedPane();
tabbedPane.addTab("Tab Page", panel1);
topPanel.add(tabbedPane, BorderLayout.CENTER);
}
public void createPage1()
{
panel1 = new JPanel();
panel1.setLayout(null);
ImageIcon pic = new ImageIcon("test.png");
JLabel label = new JLabel (pic);
panel1.add(label);
label.setVisible (true);
label.setBounds(200, 200, 200, 400);
}
// Main method to get things started
public static void main(String args[])
{
// Create an instance of the test application
Example1 mainFrame = new Example1();
mainFrame.setVisible(true);
}
}
如果您要我提供更多信息,请询问。
