複選框java_java之swing實作複選框的方法

本文執行個體講述了java之swing實作複選框的方法。分享給大家供大家參考。具體如下：

import java.awt.*;

import javax.swing.*;

import java.awt.event.*;

public class test extends JApplet

implements ItemListener{

JTextField jtf;

public void init(){

Container contentPane = getContentPane();

contentPane.setLayout(new FlowLayout());

ImageIcon a1 = new ImageIcon("D:/data/Images/6.gif");

ImageIcon a2 = new ImageIcon("D:/data/Images/7.gif");

ImageIcon a3 = new ImageIcon("D:/data/Images/8.gif");

JCheckBox cb = new JCheckBox("C", a1);

cb.setRolloverIcon(a2);

cb.setSelectedIcon(a3);

cb.addItemListener(this);

contentPane.add(cb);

cb = new JCheckBox("C++", a1);

cb.setRolloverIcon(a2);

cb.setSelectedIcon(a3);

cb.addItemListener(this);

contentPane.add(cb);

cb = new JCheckBox("java", a1);

cb.setRolloverIcon(a2);

cb.setSelectedIcon(a3);

cb.addItemListener(this);

contentPane.add(cb);

jtf = new JTextField(15);

contentPane.add(jtf);

}

public void itemStateChanged(ItemEvent ie){

JCheckBox cb = (JCheckBox)ie.getItem();

jtf.setText(cb.getText());

}

}

希望本文所述對大家的java程式設計有所幫助。
