| 方法 | 描述 |
| --- | --- |
| getAccessibleContext() | 获取与此 JToggleButton 关联的 AccessibleContext。 |
| getUIClassID() | 返回一个字符串，该字符串指定呈现此组件的 l&f 类的名称。 |
| paramString() | 返回此 JToggleButton 的字符串表示形式。 |
| updateUI() | 将用户界面属性重置为当前外观的值。 |

2。使用 ActionListener 实现 JToggleButton 事件的 Java 程序:这里，在 JFrame 上创建了一个 JToggleButton。然后，我们定义 ActionListener。 actionPerformed() 是 ActionListener() 中唯一的方法，只要点击注册的组件就会被调用。 abstractButton.getModel()。如果选择了按钮，isSelected() 返回 true，否则返回 false。将监听器连接到跳转按钮。
Java 语言(一种计算机语言，尤用于创建网站)
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.AbstractButton;
import javax.swing.JFrame;
import javax.swing.JToggleButton;
public class JToggleButtonExamp {
// Main Method
public static void main(String args[])
// create the JFrame
JFrame frame = new JFrame("Selecting Toggle");
// set default close operation for frame
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// create a ToggleButton
JToggleButton toggleButton = new JToggleButton("Toggle Button");
// Define ActionListener
ActionListener actionListener = new ActionListener()
// actionPerformed() method is invoked
// automatically whenever you click on
// registered component
public void actionPerformed(ActionEvent actionEvent)
AbstractButton abstractButton =
(AbstractButton)actionEvent.getSource();
// return true or false according
// to the selection or deselection
// of the button
boolean selected = abstractButton.getModel().isSelected();
System.out.println("Action - selected=" + selected + "\n");
// Attach Listeners
toggleButton.addActionListener(actionListener);
// add ToggleButton to the frame
frame.add(toggleButton, BorderLayout.NORTH);
// set size of the frame
frame.setSize(300, 125);
frame.setVisible(true);
