The HScrollBar (horizontal ScrollBar) control lets you control the portion of data that is displayed when there is too much data to fit in a display area. This control extends the base ScrollBar control.

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:

MXML SyntaxexpandedHide MXML Syntax

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"

Event Detail
scroll Event
Event Object Type: mx.events.ScrollEvent
property ScrollEvent.type = mx.events.ScrollEvent.SCROLL

Dispatched when the ScrollBar control scrolls through user initiated action or programmatically.

The ScrollEvent.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:

PropertyValue
bubblesfalse
cancelablefalse
currentTargetThe 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.
deltaContains 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.
directionContains the scroll direction, either ScrollEventDirection.HORIZONTAL or ScrollEventDirection.VERTICAL.
positionContains the new scroll position.
targetThe 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.
