Selection Groups

选择组

You can create a relationship between a group of shape, line, image, and/or dynamic panel widgets in which only one widget at a time can be set to its selected state with the Set Selected/Checked action. When a widget in the group is set to its selected state, all others are automatically deselected. (This is similar to the relationship between radio buttons in a radio group.)

您可以在一组形状、线条、图像和/或动态面板小部件之间创建关系，其中一次只能使用** set selected /Checked**操作将一个小部件设置为其选定状态。当组中的小部件设置为其选定状态时，其他所有小部件将自动取消选择。(这类似于单选组中的单选按钮之间的关系。)

Selection groups are handy for prototyping things like tab controls and accordion menus.

选择组对于创建标签控件和折叠式菜单之类的原型非常方便。

2、Setting a Widget to Its Selected State

将小部件设置为其选定状态

Adding widgets to a selection group is just the first step. To make use of the selection group, you'll need to create interactions that set the widgets to their selected states using the Set Selected/Checked action. A common example would be clicking a widget to select it, using the widget's Click or Tap event.
