RadioButton class

Inheritance UIObject > UIComponent > SimpleButton > Button > RadioButton

ActionScript Package Name mx.controls.RadioButton

The properties of the RadioButton class allow you at runtime to create a text label and position it in relation to the radio button. You can also assign data values to radio buttons, assign them to groups, and select them based on data value or instance name.

Setting a property of the RadioButton class with ActionScript overrides the parameter of the same name set in the Property inspector or Component Inspector panel.

The RadioButton component uses the FocusManager to override the default Flash Player focus rectangle and draw a custom focus rectangle with rounded corners. For information about creating focus navigation, see Creating custom focus navigation.

Each component class has a version property which is a class property. Class properties are only available on the class itself. The version property returns a string that indicates the version of the component. To access the version property, use the following code:

trace(mx.controls.RadioButton.version);

Note: The following code returns undefined: trace(myRadioButtonInstance.version);.
