常數詳細資訊

REMOVING

常數

public static const REMOVING:String = "removing"

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

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

常數

public static const VIEW_ACTIVATE:String = "viewActivate"

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

AIR 2.5

The ViewNavigatorEvent.VIEW_ACTIVATE constant defines the value of the type property of the event object for an viewActivate event. This event is dispatched when a component is activated.

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`	false
`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.VIEW_ACTIVATE

VIEW_DEACTIVATE

常數

public static const VIEW_DEACTIVATE:String = "viewDeactivate"

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

AIR 2.5

The ViewNavigatorEvent.VIEW_DEACTIVATE constant defines the value of the type property of the event object for an viewDeactivate event. This event is dispatched when a component is deactivated.

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`	false
`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`.
