TextField 1191

mouseWheelEnabled

(TextField.mouseWheelEnabled property)

public mouseWheelEnabled : Boolean

A Boolean value that indicates whether Flash Player should automatically scroll multiline text

fields when the mouse pointer clicks a text field and the user rolls the mouse wheel. By

default, this value is

true. This property is useful if you want to prevent mouse wheel

scrolling of text fields, or implement your own text field scrolling.

Availability: ActionScript 1.0; Flash Player 7

Example

The following example creates two text fields. The

scrollable_txt field has the

mouseWheelEnabled property set to true, so scrollable_txt scrolls when you click the field

and roll the mouse wheel. The

nonscrollable_txt field does not scroll if you click the field

and roll the mouse wheel.

var font_array:Array = TextField.getFontList().sort();

this.createTextField("scrollable_txt", this.getNextHighestDepth(), 10, 10,

240, 320);

scrollable_txt.border = true;

scrollable_txt.wordWrap = true;

scrollable_txt.multiline = true;

scrollable_txt.text = font_array.join("\n");

this.createTextField("nonscrollable_txt", this.getNextHighestDepth(), 260,

10, 240, 320);

nonscrollable_txt.border = true;

nonscrollable_txt.wordWrap = true;

nonscrollable_txt.multiline = true;

nonscrollable_txt.mouseWheelEnabled = false;

nonscrollable_txt.text = font_array.join("\n");

Mouse.onMouseWheel

If your SWF file includes a version 2 component, use the version 2 components

DepthManager class instead of the

MovieClip.getNextHighestDepth() method, which is

used in this example.
