1、图片按钮
import java.awt.*;
import javax.swing.*;
import java.net.URL;
public class JButtonDemo01 extends JFrame{
public JButtonDemo01() {
Container container = this.getContentPane();
//将一个图片变为图标
URL resource = JButtonDemo01.class.getResource("tx.png");
Icon icon = new ImageIcon(resource);
//把这个图标放在按钮上
JButton button = new JButton();
button.setIcon(icon);
button.setToolTipText("图片按钮");
//把这个按钮加到容器上
container.add(button);
this.setVisible(true);
this.setBounds(100,100,300,350);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
new JButtonDemo01();
}
}
效果：
(鼠标放到图片上，，提示“图片按钮”)
2、单选按钮（JRadioButton）
import java.awt.*;
import javax.swing.*;
public class JButtonDemo02 extends JFrame{
public JButtonDemo02() {
Container container = this.getContentPane();
//单选框
JRadioButton radioButton1 = new JRadioButton("JRadioButton01");
JRadioButton radioButton2 = new JRadioButton("JRadioButton02");
JRadioButton radioButton3 = new JRadioButton("JRadioButton03");
//由于单选框只能选择一个，所以需要分组,且一个组中只能选一个
ButtonGroup group = new ButtonGroup();
group.add(radioButton1);
group.add(radioButton2);
group.add(radioButton3);
container.add(radioButton1,BorderLayout.CENTER);
container.add(radioButton2,BorderLayout.NORTH);
container.add(radioButton3,BorderLayout.SOUTH);
this.setVisible(true);
this.setBounds(100,100,300,350);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
new JButtonDemo02();
}
}
效果：
(三选一：只能选一个)
3、复选按钮（JCheckBox）
import java.awt.*;
import javax.swing.*;
public class JButtonDemo03 extends JFrame{
public JButtonDemo03() {
Container container = this.getContentPane();
//多选框
JCheckBox checkBox01 = new JCheckBox("checkBox01");
JCheckBox checkBox02 = new JCheckBox("checkBox02");
container.add(checkBox01,BorderLayout.NORTH);
container.add(checkBox02,BorderLayout.SOUTH);
this.setVisible(true);
this.setBounds(100,100,300,350);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
new JButtonDemo03();
}
}
