Question

JAVA将一个JFrame放入另一个JFrame

做三个界面，第二、三个界面作为第一个界面的选项卡里的内容，怎么实现，新手不懂

Answer 1

1.先下载一个windowbuilder，安装到Eclipse中，就可以很容易做出来图形化的界面设计

源代码如下：
第一个Java文件Menu.java
package output;

import java.awt.BorderLayout;

public class Menu extends JFrame {

private JPanel contentPane;

/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Menu frame = new Menu();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

/**
* Create the frame.
*/
public Menu() {
setTitle("\u7B2C\u4E00\u4E2AJFrame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
setContentPane(contentPane);

JDesktopPane desktopPane = new JDesktopPane();
desktopPane.setBackground(Color.ORANGE);
contentPane.add(desktopPane, BorderLayout.CENTER);

JButton btnframe = new JButton("\u7B2C\u4E8C\u4E2AJFrame");
btnframe.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
One frame = new One();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
});
btnframe.setBounds(60, 60, 155, 23);
desktopPane.add(btnframe);

JButton btnjframe = new JButton("\u7B2C\u4E09\u4E2AJFrame");
btnjframe.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Two frame = new Two();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
});
btnjframe.setBounds(57, 114, 158, 23);
desktopPane.add(btnjframe);
}
}

第二个文件One.java
package output;

import java.awt.BorderLayout;

public class One extends JFrame {

private JPanel contentPane;

/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
One frame = new One();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

/**
* Create the frame.
*/
public One() {
setTitle("\u7B2C\u4E8C\u4E2AJFrame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBackground(Color.GREEN);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
setContentPane(contentPane);
}

}

第三个Java文件

package output;

import java.awt.BorderLayout;

public class Two extends JFrame {

private JPanel contentPane;

/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Two frame = new Two();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

/**
* Create the frame.
*/
public Two() {
setTitle("\u7B2C\u4E09\u4E2AJFrame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBackground(Color.BLUE);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
contentPane.setLayout(new BorderLayout(0, 0));
setContentPane(contentPane);
}

}

追问

我们这个是考试内容，不能够抄捷径的，不过还是非常感谢你，下次做开发的时候会用windowbuilder

Answer 2

public class c
{
public static void main (String args[])
{
JButton b = new JButton(new a().t);
JFrame w = new JFrame();
w.setLayout(null);
b.setBounds(20,20,100,20);
w.add(b);
w.setSize(500,500);
b.addActionListener(new ActionListener()
{
@Override
public void actionPerformed(ActionEvent e)
{
new a().setVisible(true);
}
});
w.setVisible(true);
w.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
class a extends JFrame
{
ImageIcon t = new ImageIcon("E:\\Q.png");
JLabel l = new JLabel(t);
public a()
{
l.setBounds(0,0,t.getIconWidth(),t.getIconHeight());
add(l);
setLayout(null);
setLocation(0,0);
setSize(500,500);
setVisible(false);
}
}

用第一个界面上的按钮打开第二个界面~
我也是新手~

追问

额，我的意思是在同一个窗口中第一个界面的选项卡中包含第二个界面，不是新产生一个窗口

追答

原来如此 献丑了~ 这个问题很深奥啊~ 咱不是很明白~
