![]() | Starting with Flex 4.0, Apache recommends that you use the spark.components.HScrollBar class as an alternative to this class. |
Although you can use the HScrollBar 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 buttons depend on the current state of the control. The ScrollBar control uses four parameters to calculate its display state:
The <mx:HScrollBar>
tag inherits all of the
tag attributes of its superclass, and adds the following tag attributes:
<mx:HScrollBar Styles repeatDelay="500" repeatInterval="35" Events scroll="No default" />

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. |
