java之swing实现复选框的方法

本文实例讲述了java之swing实现复选框的方法。分享给大家供大家参考。具体如下：

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());
  }
}

希望本文所述对大家的java程序设计有所帮助。
