SwitchDelegate presents an item delegate that can be toggled on (checked) or off (unchecked). Switch delegates are typically used to select one or more options from a set of options. For smaller sets of options, or for options that need to be uniquely identifiable, consider using Switch 代替。
SwitchDelegate inherits its API from ItemDelegate , which is inherited from AbstractButton . For instance, you can set text , and react to clicks 使用 AbstractButton API. The state of the switch delegate can be set with the checked 特性。
