JFrame：如何禁用窗口大小调整？ [英] JFrame: How to disable window resizing?

问题描述

我正在创建 JFrame ，我调用方法 setSize（500,500）。现在，期望的行为是用户不应在任何条件下调整JFrame的大小。通过最大化或拖动边框。它应该是500x500。我该怎么做？我还附上了代码，以防你更好地指导我。

I am creating a JFrame and I call the method setSize(500, 500). Now the desired behaviour is that JFrame should not be resized by user in any condition. Either by maximizing or by dragging the borders. It should be 500x500. How can I do it? I have also attached the code in case you can guide me better.

    package com.techpapa;    
    import javax.swing.*;  
    import java.awt.*;  
    import java.awt.event.*;  

    public class MainWindow extends JFrame{


private JTextField
            write;
private JRadioButton
            rb1,
            rb2,
            rb3;
private ButtonGroup
            bg;

private ActionListener al = new ActionListener(){
    public void actionPerformed(ActionEvent e){
        write.setText("JRadioButton : " + ((JRadioButton)e.getSource()).getText());
    }

};

public MainWindow(){
    //Frame Initialization
    setSize(500, 500);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    setLayout(null);
    setTitle(".:JRadioButton:.");
    setVisible(true);

    //Components Initialization
    write = new JTextField(20);
    write.setEditable(false);
    rb1 = new JRadioButton("Male", false);
    rb1.addActionListener(al);
    rb2 = new JRadioButton("Female", false);
    rb2.addActionListener(al);
    rb3 = new JRadioButton("I don't want to specify", true);
    rb3.addActionListener(al);
    bg = new ButtonGroup();

    //Add radio buttons to buttongroup
    bg.add(rb1); bg.add(rb2); bg.add(rb3);

    //Add to window
    add(write);
    write.setBounds(140, 100, 150, 20);
    write.setDragEnabled(true);
    add(rb1);
    rb1.setBounds(180, 200, 100, 30);
    add(rb2);
    rb2.setBounds(180, 225, 100, 30);
    add(rb3);
    rb3.setBounds(180, 250, 130, 30);

}

public static void main(String[] args) {
    new MainWindow();

}

}

推荐答案

你可以在帧初始化下的构造函数中使用一个简单的调用：

You can use a simple call in the constructor under "frame initialization":

setResizable(false);

此次通话后，窗口将无法调整大小。

After this call, the window will not be resizable.
