public class JCheckBox
- extends JToggleButton
- implements Accessible
复选框的实现,复选框是一个可以被选定和取消选定的项,它将其状态显示给用户。按照惯例,可以选定组中任意数量的复选框。有关使用复选框的示例和信息,请参阅 The Java Tutorial 中的 How to Use Buttons, Check Boxes, and Radio Buttons。
通过 Action
可配置按钮,并进行某种程度的控制。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 Action
的 Swing 组件,可在 The Java Tutorial 中的 How
to Use Actions 一节找到更多信息。
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:此类的序列化对象将与以后的 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
