什么是图形用户界面，设计方法有几种

你WINDOWS这种用图形来接受用户的 *** 作的界面就是图形用户界面，而像早期的DOS *** 作系统就是非图形用户界面，它是用DOS命令来 *** 作的。至于设计方法，现在的所见所得的编程语言设计的者是图形用户界面，像VC、VB、VF等。

运行如图

参考代码如下

import java.awt.*

import java.awt.event.*

import javax.swing.*

public class RegDemo extends JFrame implements ActionListener{

JTextField jtf

JPasswordField jpf

public RegDemo() {

        //组件的创建, 和布局安排

JPanel jpc = new JPanel()//默认流式布局

JPanel jp1 = new JPanel(new GridLayout(2, 2,5,10))//网格布局

jp1.setBorder(BorderFactory.createTitledBorder("用户注册"))

JLabel jl1 = new JLabel("用户名:")

jtf = new JTextField(10)

JLabel jl2 = new JLabel("密码:")

jpf = new JPasswordField(10)

                jpf.setEchoChar('*')//用*号来隐藏密码的显示

jp1.add(jl1)jp1.add(jtf)

jp1.add(jl2)jp1.add(jpf)

jpc.add(jp1)

add(jpc)

JButton jb1 = new JButton("提交")

jb1.addActionListener(this)

jb1.setActionCommand("yes")

JButton jb2 = new JButton("取消")

jb2.addActionListener(this)

jb2.setActionCommand("no")

JPanel jp2 = new JPanel()

jp2.add(jb1)jp2.add(jb2)

add(jp2,BorderLayout.SOUTH)

setTitle("用户注册界面")

        setSize(280, 280)

        setLocationRelativeTo(null)//窗口居中

        setDefaultCloseOperation(EXIT_ON_CLOSE)//

        setVisible(true)

}

public static void main(String[] args) {

new RegDemo()

}

@Override

public void actionPerformed(ActionEvent e) {

if(e.getActionCommand().equals("yes")){

String name  = jtf.getText().trim()

String pwd = new String(jpf.getPassword())

if(name.equals("")||pwd.equals("")){

JOptionPane.showMessageDialog(this, "你还没有输入用户名或者密码")

}else{

JOptionPane.showMessageDialog(this, "注册成功!用户名"+name+",密码"+pwd)

}

}else{

jtf.setText("")

jpf.setText("")

}

}

}

程序如下：

import java.awt.FlowLayout

import java.awt.event.ActionEvent

import java.awt.event.ActionListener

import javax.swing.ButtonGroup

import javax.swing.JButton

import javax.swing.JCheckBox

import javax.swing.JFrame

import javax.swing.JPanel

import javax.swing.JRadioButton

import javax.swing.JTextArea

public class JFrameDemo extends JFrame implements ActionListener

{

private JPanel panel

private JButton button

private JTextArea textArea

private JCheckBox musicBox

private JCheckBox danceBox

private JRadioButton hanButton

private JRadioButton manButton

private JRadioButton huiButton

private ButtonGroup buttonGroup

public JFrameDemo()

{

panel = new JPanel()

button = new JButton("确定")

textArea = new JTextArea(40,30)

musicBox = new JCheckBox("唱歌")

danceBox = new JCheckBox("跳舞")

huiButton = new JRadioButton("回族")

hanButton = new JRadioButton("汉族")

manButton = new JRadioButton("满族")

buttonGroup = new ButtonGroup()

buttonGroup.add(huiButton)

buttonGroup.add(hanButton)

buttonGroup.add(manButton)

panel.setLayout(new FlowLayout(3))

panel.add(huiButton)

panel.add(hanButton)

panel.add(manButton)

panel.add(musicBox)

panel.add(danceBox)

panel.add(button)

panel.add(textArea)

add(panel)

setTitle("选择兴趣爱好")

setBounds(100, 100, 400, 280)

setResizable(false)

setVisible(true)

this.button.addActionListener(this)

}

public static void main(String[] args)

{

new JFrameDemo()

}

@Override

public void actionPerformed(ActionEvent e)

{

if(e.getSource() == this.button)

{

String info = ""

if(this.huiButton.isSelected())

{

info += this.huiButton.getText() + "\n"

}

if(this.hanButton.isSelected())

{

info += this.hanButton.getText() + "\n"

}

if(this.manButton.isSelected())

{

info += this.manButton.getText() + "\n"

}

if(this.danceBox.isSelected())

{

info += this.danceBox.getText() + "\n"

}

if(this.musicBox.isSelected())

{

info += this.musicBox.getText() + "\n"

}

this.textArea.setText(info)

}

}

}
