Constant Detail

REMOVING | Constant

`public static const REMOVING:String = removing`

Language Version : | ActionScript 3.0

Product Version : | Flex 4.5

Runtime Versions : | AIR 2.5

The `ViewNavigatorEvent.REMOVING` constant defines the value of the `type` property of the event object for an `removing` event. This event is dispatched when a screen is about to be replaced by another screen through a navigator action. If `preventDefault()` is called on this event, the view removal will be canceled.

The properties of the event object have the following values:

Property | Value
--- | ---
`action` | The navigation action committed by the view navigator that resulted in the event.
`bubbles` | false
`cancelable` | true
`returnValue` | null
`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.
`Type` | ViewNavigatorEvent.SCREEN_REMOVING

VIEW_ACTIVATE | Constant |

`public static const VIEW_ACTIVATE:String = viewActivate`

Language Version : | ActionScript 3.0

Product Version : | Flex 4.5

Runtime Versions : | AIR 2.5

Property | Value
--- | ---
`action` | The navigation action committed by the view navigator that resulted in the event.
`bubbles` | false
`cancelable` | false
