@JavaBean(description="A component which can display it\'s state as selected or deselected.")public class JRadioButtonextends JToggleButtonimplements Accessible
单选按钮的实现 - 可以选择或取消选择的项目,并向用户显示其状态。 与ButtonGroup
对象一起使用以创建一组按钮,其中一次只能选择一个按钮。 (创建一个ButtonGroup对象并使用其add
方法在组中包含JRadioButton对象。)Note: The ButtonGroup object is a logical grouping -- not a physical grouping. To create a button panel, you should still create a
JPanel
or similar container-object and add aBorder
to it to set it off from surrounding components.按钮可以通过
Action
进行配置,并在某种程度上受到控制。 使用带按钮的Action
除了直接配置按钮之外还有许多其他好处。 有关更多详细信息,请参阅Swing Components SupportingAction
,您可以在“Java教程”中的How to Use Actions部分中找到更多信息。有关更多文档,请参阅The Java Tutorial中的 How to Use Buttons, Check Boxes, and Radio Buttons 。
