overrides property specifies a set of child classes
to add or remove from the base view state, and properties, styles, and event
handlers to set when the view state is in effect.
You use the State class in the states property
of Flex components.
You can only specify a states property at the root of an
application or a custom control, not on child controls.
You enable a view state by setting a component's
currentState property.

The name of the view state upon which this view state is based, or
null if this view state is not based on a named view state.
If this value is null, the view state is based on a root
state that consists of the properties, styles, event handlers, and
children that you define for a component without using a State class.
El valor predeterminado es null.

public var name:String| Versión del lenguaje: | ActionScript 3.0 |

The name of the view state. State names must be unique for a given component. This property must be set.

The overrides for this view state, as an Array of objects that implement the IOverride interface. These overrides are applied in order when the state is entered, and removed in reverse order when the state is exited.
The following Flex classes implement the IOverride interface and let you define the view state characteristics:
- AddChild
- RemoveChild
- SetEventHandler
- SetProperty
- SetStyle
The overrides property is the default property of the
State class. You can omit the <mx:overrides> tag
and its child <mx:Array>tag if you use MXML tag
syntax to define the overrides.

| Versión de producto: | Flex 3 |

Dispatched after a view state has been entered.
TheFlexEvent.ENTER_STATE constant defines the value of the
type property of the event object for a enterState event.
This event will only be dispatched when there are one or more relevant listeners attached to the dispatching object.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |

Dispatched just before a view state is exited. This event is dispatched before the changes to the default view state have been removed.
TheFlexEvent.EXIT_STATE constant defines the value of the
type property of the event object for a exitState event.
This event will only be dispatched when there are one or more relevant listeners attached to the dispatching object.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
