JFrame:如何禁用窗口大小调整?

我正在创建一个,JFrame然后调用该方法setSize(500,

500)。现在,所需的行为是在任何情况下用户都不应调整JFrame的大小。通过最大化或拖动边框。应该是500x500。我该怎么做?我还附上了代码,以防您能更好地指导我。

    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();

}

}

回答:

您可以在构造函数的“帧初始化”下使用一个简单的调用:

setResizable(false);

调用之后,窗口将无法调整大小。
