我将如何禁用文本框? [英] How would i disable a text box?

问题描述

所以我正在做一个项目，我试图从程序中禁用框架和字段，以便只有窗口在前面是这个窗口处于活动状态这是我的代码:

SO i am working on a project and i was trying to disable the frame and the field from the program so that only the window is front is this one being active here is my code :

 import javax.swing.*;
 import java.awt.event.*;
 import java.awt.*;

public class password
{
  private static String password = "pass";
  public static void main(String[]args) {
    JFrame frame = new JFrame("Password");
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400,100);
    JLabel label = new JLabel("Enter password");
    JPanel panel = new JPanel();
    frame.add(panel);
    JPasswordField pass = new JPasswordField(10);
    pass.setEchoChar('*');
    pass.addActionListener(new AL());
    panel.add(label, BorderLayout.WEST);
    panel.add(pass, BorderLayout.WEST);
}
static class AL implements ActionListener
{
    public void actionPerformed(ActionEvent e) {
        JPasswordField input = (JPasswordField) e.getSource();
        char [] passy = input.getPassword();
        String p = new String(passy);
        if (p.equals(password)){
            JOptionPane.showMessageDialog(null, "Correct");
            System.out.print("Welcome to Adam's Quirky program.");



        }
        else
            JOptionPane.showMessageDialog(null, "Incorrect");
       }
    }
 }

我目前用来编程的程序是 Eclipse.

推荐答案

我想看看模态对话框.

要么使用 JOptionPane，要么使用你自己的.

Either use a JOptionPane or roll your own.

如果这些不适合您的需求，请尝试查看 JLayer (Java 7) 或 JXLayer(Java 6 及以下)

If these don't suit your needs, try taking a look at JLayer (Java 7) or JXLayer (Java 6 and below)

看看 LockableUI(这是有点过时，但基本思路是一样的)

Have a look at LockableUI (It's a little out of date, but the basic idea is the same)

如果这不吸引人，您可以使用阻挡玻璃板"

If that doesn't appeal, you could use a "blocking glass pane"

看看

• glassPane 不会阻止输入
• 这个阻塞 GlassPane 有问题吗?

举个例子
