Class	public class InteractiveIcon
Inheritance	InteractiveIcon Icon EventDispatcher Object
Subclasses	DockIcon, SystemTrayIcon

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

The InteractiveIcon class is the base class for the operating system icons associated with applications.

Use the icon property of the NativeApplication object to get an instance of the application icon. The icon type will be one of the subclasses of InteractiveIcon, either DockIcon on Mac OS X^® or SystemTrayIcon on Windows^® and Linux.

You cannot instantiate the InteractiveIcon class directly. Calls to the new InteractiveIcon() constructor will throw an ArgumentError exception.

Property Detail

bitmaps

property

bitmaps:Array[override]

Runtime Versions:

AIR 1.0

The icon image as an array of BitmapData objects of different sizes.

When an icon is displayed in a given operating system context, the bitmap in the array closest to the displayed size is used (and scaled if necessary). Common sizes include 16x16, 32x32, 48x48, and 128x128. (512x512 pixel icons may be used for some operating system icons in the near future.)

In some contexts, the operating system may use a default system icon if nothing has been assigned to the bitmaps property. In other contexts, no icon appears.

To set or change the icon appearance, assign an array of BitmapData objects to the bitmaps property:

     icon.bitmaps = new Array(icon16x16.bitmapData, icon128x128.bitmapData);

Modifying the bitmaps array directly has no effect.

To clear the icon image, assign an empty array to the bitmaps property.

Note: When loading image files for an icon, the PNG file format generally provides the best alpha blending. The GIF format supports only on or off transparency (no blending). The JPG format does not support transparency at all.

Implementation
override public function get bitmaps():Array
override public function set bitmaps(value:Array):void

height

property

height:int [read-only]

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

The current display height of the icon in pixels.

Some icon contexts support dynamic sizes. The height property indicates the height of the icon chosen from the bitmaps array for the current context. The actual display height may be different if the operating system has scaled the icon.

Implementation
public function get height():int

width

property

width:int [read-only]

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

The current display width of the icon in pixels.

Some icon contexts support dynamic sizes. The width property indicates the width of the icon chosen from the bitmaps array for the current context. The actual display width may be different if the operating system has scaled the icon.

Implementation
public function get width():int
