class View
extends mx.core.UIComponent

The View class is an abstract base class. You do not create an instance of a View itself in an application. Instead, you create an instance of one of View`s subclasses, such as Canvas or HBox.

The View class contains methods for creating and destroying children. It also contains the getChildAt method, and the logic for drawing the background and border of the View instance.

Common MXML Syntax Inherited from View

Flex components inherit the following properties from the View class. 

 <mx:tagname
   numchildren=No default.

Events
childCreatedBroadcast after a child has been created in a container. The relatedNode property of the event object contains a copy of the created child object. Target contains a reference to the component that triggered the event. Type contains the name of the event.
childIndexChangedBroadcast after a container child`s index has changed. The event object contains the following properties:
- relatedNode Contains a copy of the created child object.
- prevValue Contains the child`s old index.
- newValue Contains the child`s new index.
Target contains a reference to the component that triggered the event. Type contains the name of the event.
childDestroyedBroadcast before a child of a container is destroyed. The relatedNode property of the event object contains a copy of the destroyed child object. Target contains a reference to the component that triggered the event. Type contains the name of the event.
