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.
