Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

The ScrollBar component provides the end user with a way to control the portion of data that is displayed when there is too much data to fit in the display area. The scroll bar consists of four parts: two arrow buttons, a track, and a thumb. The position of the thumb and display of the buttons depends on the current state of the scroll bar. The scroll bar uses four parameters to calculate its display state: a minimum range value; a maximum range value; a current position that must be within the range values; and a viewport size that must be equal to or less than the range and represents the number of items in the range that can be displayed at the same time.

direction

property
direction:String

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

Gets or sets a value that indicates whether the scroll bar scrolls horizontally or vertically. Valid values are ScrollBarDirection.HORIZONTAL and ScrollBarDirection.VERTICAL.

The default value is ScrollBarDirection.VERTICAL.



Implementation
    public function get direction():String
    public function set direction(value:String):void

enabled

property 
enabled:Boolean[override]

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

Gets or sets a Boolean value that indicates whether the scroll bar is enabled. A value of true indicates that the scroll bar is enabled; a value of false indicates that it is not.

The default value is true.



Implementation
    override public function get enabled():Boolean
    override public function set enabled(value:Boolean):void

height

property 
height:Number[override]

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

Gets or sets the height of the component, in pixels.

Setting this property causes a resize event to be dispatched. See the resize event for detailed information about when it is dispatched.

If the scaleY property of the component is not 1.0, the height of the component that is obtained from its internal coordinates will not match the height value from the parent coordinates. For example, a component that is 100 pixels in height and has a scaleY of 2 has a value of 100 pixels in the parent, but internally stores a value indicating that it is 50 pixels in height.



Implementation
    override public function get height():Number
    override public function set height(value:Number):void

lineScrollSize

property 
lineScrollSize:Number

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

Gets or sets a value that represents the increment by which to scroll the page when the scroll bar track is pressed. The pageScrollSize is measured in increments between the minScrollPosition and the maxScrollPosition values. If this value is set to 0, the value of the pageSize property is used.

The default value is 0.

maxScrollPosition

property 
maxScrollPosition:Number

Language Version: ActionScript 3.0
Product Version: Flash CS3
Runtime Versions: Flash Player 9.0.28.0, AIR 1.0

Gets or sets a number that represents the maximum scroll position. The scrollPosition value represents a relative position between the minScrollPosition and the maxScrollPosition values. This property is set by the component that contains the scroll bar, and is the maximum value. Usually this property describes the number of pixels between the bottom of the component and the bottom of the content, but this property is often set to a different value to change the behavior of the scrolling. For example, the TextArea component sets this property to the maxScrollH value of the text field, so that the scroll bar scrolls appropriately by line of text.

The default value is 0.



Implementation
    public function get maxScrollPosition():Number
    public function set maxScrollPosition(value:Number):void

minScrollPosition

property

Gets or sets a number that represents the minimum scroll position. The scrollPosition value represents a relative position between the minScrollPosition and the maxScrollPosition values. This property is set by the component that contains the scroll bar, and is usually zero.

The default value is 0.

For example, the disabledTextFormat style contains a value of null or a TextFormat object. You can use these styles and call setStyle() on the current component. The following code overrides the default disabledTextFormat style on the specified component:

componentInstance.setStyle("disabledTextFormat", new TextFormat());
