所以我为我的项目制作了一个程序。 当我点击一个按钮时，它必须打开anohter框架并使按钮不可点击。当您关闭弹出框时，该按钮必须重新启用。所以这是
我的主框架
package Option2;
import javax.swing.event.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class MainMenu {
int intCtr1 = 0;
JFrame frame1 = new JFrame("EXD LAN PARTY");
JButton Button1 = new JButton();
JButton Button2 = new JButton();
JButton Button3 = new JButton();
JButton Button4 = new JButton();
JLabel Label1 = new JLabel();
public void MainMenu(){
//BUTTON1
Button1.setIcon(new javax.swing.ImageIcon(getClass().getResource("/Option2/PI2.jpg")));
Button1.setBackground(Color.white);
Button1.setBounds(50, 350, 150, 150);
Button1.setToolTipText("Personal Info");
//BUTTON1 END
//BUTTON2
Button2.setIcon(new javax.swing.ImageIcon(getClass().getResource("/Option2/PC.jpg")));
Button2.setBackground(Color.white);
Button2.setBounds(250, 350, 150, 150);
Button2.setToolTipText("PC INFO");
//BUTTON2 END
//BUTTON3
Button3.setIcon(new javax.swing.ImageIcon(getClass().getResource("/Option2/Games.jpg")));
Button3.setBackground(Color.white);
Button3.setBounds(450, 350, 150, 150);
Button3.setToolTipText("Games");
//BUTTON3 END
//BUTTON4 END
Button4.setIcon(new javax.swing.ImageIcon(getClass().getResource("/Option2/Players.jpg")));
Button4.setBackground(Color.white);
Button4.setBounds(650, 350, 150, 150);
Button3.setToolTipText("Players");
//BUTTON4 END
//LABEL1
Label1.setIcon(new javax.swing.ImageIcon(getClass().getResource("/Option2/EXD.jpg")));
Label1.setBounds(50, 50, 800, 250);
//LABEL1 END
//Frame1
frame1.getContentPane().setBackground(Color.black);
frame1.setResizable(false);
frame1.setLayout(null);
frame1.setSize(870,650);
frame1.setVisible(true);
frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame1.add(Label1);
frame1.add(Button1);
frame1.add(Button2);
frame1.add(Button3);
frame1.add(Button4);
//Frame1 END
Button1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a){
PersonalInfo objPI = new PersonalInfo();
objPI.Menu1();
Button1.setEnabled(false);
}
});
Button2.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a){
PCInfo objPCI = new PCInfo();
objPCI.Menu2();
}
});
Button3.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a){
Games objGames = new Games();
objGames.Menu3();
}
});
Button4.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a){
Players objPlayers = new Players();
objPlayers.Menu4();
}
});
}
public void dim1(){
if(intCtr1 == 1){
MainMenu objMM = new MainMenu();
objMM.Button1.setEnabled(true);
System.out.println("SD");
}
}
}
**and this is my sub frame**

当我点击一个按钮时，它必须打开anohter框架
您不应该创建另一个JFrame。
相反，您应该创建一个modal JDialog。在对话框关闭之前，对话框不允许您单击框架。

遵循Java命名约定。变量名称不应以大写字符开头。有时您遵循本指南，有时您不遵守此指南。保持一致！
请勿使用setBounds(...)。 Swing旨在与layout managers一起使用！
答案 1 :(得分：1)
首先，请阅读Java naming conventions。
您需要将MainMenu的引用传递给PersonalInfo才能实现您的需求，这里：
button1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a){
PersonalInfo objPI = new PersonalInfo(this);
objPI.menu1();
button1.setEnabled(false);
}
});
您需要向PersonalInfo添加构造函数：
private MainMenu m;
public PersonalInfo(MainMenu m) {
this.m = m;
}
向MainMenu添加公共方法：
public void enableMyButton() {
button1.setEnabled(true);
}
现在您可以向PersonalInfo添加一个事件监听器以启用MainMenu框架的按钮：
frame1.addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
this.m.enableMyButton();
}
});
