Runtime Versions : | Flash Player 9, AIR 1.1 |
Starting with Flex 4.0, Apache recommends that you use the spark.components.VScrollBar class as an alternative to this class. |
Although you can use the VScrollBar control as a stand-alone control, you usually combine it as part of another group of components to provide scrolling functionality.
A ScrollBar control consist of four parts: two arrow buttons, a track, and a thumb. The position of the thumb and the display of the arrow buttons depend on the current state of the ScrollBar control. The ScrollBar control uses four parameters to calculate its display state:
The <mx:VScrollBar>
tag inherits all the
tag attributes of its superclass, and adds the following tag attributes:
<mx:VScrollBar Styles repeatDelay="500" repeatInterval="35" Events scroll="No default" />

mx.events.ScrollEvent.SCROLL
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Dispatched when the ScrollBar control scrolls through user initiated action or programmatically.
TheScrollEvent.SCROLL
constant defines the value of the
type
property of the event object for a scroll event.
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 . |
delta | Contains the change in scroll position, expressed in pixels. A positive value indicates the scroll was down or to the right. A negative value indicates the scroll was up or to the left. |
direction | Contains the
scroll direction, either ScrollEventDirection.HORIZONTAL or
ScrollEventDirection.VERTICAL . |
position | Contains the new scroll position. |
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. |
