You can use the DockIcon class to change the appearance of the standard icon; for example, to animate the icon or add informational graphics. You can also add items to the dock icon menu. The menu items that you add are displayed above the standard menu items.
An instance of the DockIcon class cannot be created. Get the object
representing the operating system dock icon from NativeApplication.icon.
Not all operating systems have dock icons. Check NativeApplication.supportsDockIcon
to determine whether dock icons are supported on the current system. If dock
icons are supported, the NativeApplication.icon property is of type
DockIcon. Otherwise, the type of NativeApplication.icon is another
subclass of InteractiveIcon, typically SystemTrayIcon.
Important: Attempting to call a DockIcon class method on the
NativeApplication.icon object on an operating system for which AIR does not support dock icons
generates a run-time exception.

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.
| height | property |
height:int [read-only] [override] | Runtime Versions: | 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.
| menu | property |
menu:NativeMenu| Runtime Versions: | 1.0 |
The system-supplied menu of this dock icon.
Any items in the menu are displayed above the standard items. The standard items cannot be modified or removed.
| width | property |
width:int [read-only] [override] | Runtime Versions: | 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.
| bounce | () | method |
function bounce(priority:String = informational):void| Runtime Versions: | 1.0 |
Notifies the user that an event has occurred that may require attention.
Calling this method bounces the dock icon if, and only if, the
application is in the background. If the priority is
NotificationType.Informational then the icon bounces once.
If the priority is NotificationType.Critical then the
icon bounces until the application is brought to the foreground.
Parameters
priority:String (default = informational) |
