JavaTM 2 Platform Standard Edition 6.0 API 规范中文版
JButton (Java Platform SE 6) - JavaTM 2 Platform Standard Edition 6.0 API 规范中文版
javax.swing
类 JButton
java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.AbstractButton
javax.swing.JButton
- 所有已实现的接口：
- ImageObserver, ItemSelectable, MenuContainer, Serializable, Accessible, SwingConstants
- 直接已知子类：
- BasicArrowButton, MetalComboBoxButton
public class JButton
- extends AbstractButton
- implements Accessible
"push" 按钮的实现。
通过 Action 可配置按钮，并进行一定程度的控制。将 Action 用于按钮具有许多直接配置按钮所不及的优点。有关更多详细信息，请参阅支持的 Action Swing 组件，可在 The Java Tutorial 中的 How
to Use Actions 一节找到更到信息。
有关使用按钮的更多信息和示例，请参阅 The Java Tutorial 中的 How to Use Buttons, Check Boxes, and Radio Buttons。
警告： Swing 不是线程安全的。有关更多信息，请参阅 Swing's Threading
Policy。
警告：此类的序列化对象与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储，或适用于在运行相同 Swing 版本的应用程序之间进行 RMI（Remote Method Invocation，远程方法调用）。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeansTM 长期存储的功能。请参见 XMLEncoder。
