我之前曾尝试过此操作，但失败了。
如何将JButton添加到JFrame，将其带回到先前打开的JFrame或“主页”框架。
在我的应用程序中，我有4个JFrame，主要的1个和3个可通过按钮访问的JFrame。
我的完整代码（很久很抱歉）

最佳答案
如何使用一个布局，CardLayout和四个JPanel以及要使用的内容。它具有三个不错的功能：将其视为卡片的布局组件：CardLayout.first(Caontainer)：翻转到容器的第一张卡。CardLayout.next(panel)：翻转到指定容器的下一张卡片。如果当前可见的卡片是最后一张卡片，则此方法将翻转到布局中的第一张卡片。CardLayout.previous(paenl)：翻转到指定容器的上一张卡。如果当前可见的卡片是第一张卡片，则此方法将翻转到布局中的最后一张卡片。
这是一个适合您的工作示例：
class CardLayoutDemo1 extends JFrame {
private JPanel jPanel1;
private JButton navHomeButt;
private JButton navNextButt;
private JButton navPreviousButt;
private JPanel panelContainer;
Random random = new Random();
public CardLayoutDemo1() {
initComponents();
panelContainer.add(createSamplePanel("Home Panel "), ""+0);
for(int i=1; i < 10; i++)
{
panelContainer.add(createSamplePanel("Panel "+i), ""+i);
}
}
private void initComponents() {
jPanel1 = new JPanel();
navPreviousButt = new JButton();
navNextButt = new JButton();
navHomeButt = new JButton();
panelContainer = new JPanel();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
jPanel1.setBackground(Color.WHITE);
navPreviousButt.setText("Previous");
navPreviousButt.setPreferredSize(new Dimension(90, 23));
jPanel1.add(navPreviousButt);
navNextButt.setText("next");
navNextButt.setPreferredSize(new Dimension(90, 23));
jPanel1.add(navNextButt);
navHomeButt.setText("Back to Home");
jPanel1.add(navHomeButt);
panelContainer.setPreferredSize(new Dimension(400, 300));
panelContainer.setLayout(new CardLayout());
// setting the card layout
getContentPane().add(jPanel1, java.awt.BorderLayout.PAGE_END);
getContentPane().add(panelContainer, BorderLayout.CENTER);
navNextButt.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
CardLayout cardLayout = (CardLayout) panelContainer.getLayout();
cardLayout.next(panelContainer);
// using cardLayout next() to go to next panel
}
});
navHomeButt.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
CardLayout cardLayout = (CardLayout) panelContainer.getLayout();
cardLayout.first(panelContainer);
// suing first to get to the home panel
}
});
navPreviousButt.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
CardLayout cardLayout = (CardLayout) panelContainer.getLayout();
cardLayout.previous(panelContainer);
// using previous to get to previous(left)panel
}
});
pack();
}
public JPanel createSamplePanel(String panelTitle)
{
JPanel samplePanel = new JPanel();
samplePanel.add(new JLabel(panelTitle));
samplePanel.setBackground(new Color(random.nextInt(255), random.nextInt(255), random.nextInt(255)));
return samplePanel;
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new CardLayoutDemo1().setVisible(true);
}
});
}
}
