| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
By default, the BaseScrollPane class is extended by the ScrollPane and SelectableList classes, for all list-based components. This means that any component that uses horizontal or vertical scrolling does not need to implement any scrolling, masking or layout logic, except for behavior that is specific to the component.

BaseScrollPane | () | Constructor |
public function BaseScrollPane()| Language Version: | ActionScript 3.0 |

getStyleDefinition | () | method |
public static function getStyleDefinition():Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Retrieves the default style map for the current component. The style map contains
the type that is appropriate for the component, depending on the style that
the component uses. 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());Object — Default styles object.

fl.events.ScrollEvent.SCROLL| Language Version: | ActionScript 3.0 |
| Product Version: | Flash CS3 |
| Runtime Versions: | Flash Player 9.0.28.0, AIR 1.0 |
Dispatched when the user scrolls content by using the scroll bars on the component or the wheel on a mouse device.
Defines the value of thetype property of a scroll
event object.
This event has the following properties:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false; there is no default
behavior to cancel. |
currentTarget | The object that is actively processing the event object with an event listener. |
delta | 1; a value that indicates
how much scrolling was done.
|
direction | vertical; the direction of the
ScrollBar. |
position | 0; the position of the
Scrollbar thumb after it was moved. |
target | The object that dispatched the event. The target is
not always the object listening for the event. Use the currentTarget
property to access the object that is listening for the event. |
Example ( How to use this example )
The following example listens for the
scroll event
and uses the direction property of the ScrollEvent class to
determine if the content was scrolled horizontally or vertically:
import fl.containers.ScrollPane;
import fl.events.ScrollEvent;
import fl.controls.ScrollBarDirection;
var myScrollPane:ScrollPane = new ScrollPane();
myScrollPane.scrollDrag = true;
myScrollPane.source = "http://www.helpexamples.com/flash/images/image1.jpg";
myScrollPane.addEventListener(ScrollEvent.SCROLL, scrollHandler);
addChild(myScrollPane);
function scrollHandler(event:ScrollEvent):void {
switch (event.direction) {
case ScrollBarDirection.HORIZONTAL:
trace("horizontal scroll", event.position, "of", event.currentTarget.maxHorizontalScrollPosition);
break;
case ScrollBarDirection.VERTICAL:
trace("vertical scroll", event.position, "of", event.currentTarget.maxVerticalScrollPosition);
break;
