Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

A TextLayoutEvent instance represents an event, such as the TextLayoutEvent.SCROLL event, that does not require custom properties.

A scroll event is represented by a TextLayoutEvent instance with its type property set to TextLayoutEvent.SCROLL. A class specifically for scroll events is not necessary because there are no custom properties for a scroll event, as there are for the other events that have specific event classes. If a new text layout event is needed, and the event does not require custom properties, the new event will also be represented by a TextLayoutEvent object, but with its type property set to a new static constant.

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

bubbles:Boolean (default = false)

Constant Detail

SCROLL

Constant
public static const SCROLL:String = "scroll"

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The TextLayoutEvent.SCROLL constant defines the value of the type property of the event object for a scroll event.

TextLayoutEvent_example.as

This example shows how to create an event handler that listens for a scroll event. The two key steps are to call the addEventListener() method on the text flow and to create an event handler function.

Call the addEventListener() method on the TextFlow instance. You can use the simple string "text", but it is safer to use the static constant TextLayoutEvent.SCROLL

The event handler function in this example is named scrollEventHandler(). The event handler executes a trace() statement whenever a scroll event is detected. This example does not include a scroll bar, but the text scrolls when a user highlights text and drags the cursor down past the bottom of the container.
