InheritanceSystemTrayIcon Inheritance InteractiveIcon Inheritance Icon Inheritance EventDispatcher Inheritance Object

The SystemTrayIcon class represents the Windows taskbar® notification area (system tray)-style icon.

Not all operating systems have system tray icons. Check NativeApplication.supportsSystemTrayIcon to determine whether system tray icons are supported on the current system.

An instance of the SystemTrayIcon class cannot be created. Get the object representing the system tray icon from the icon property of the "global" NativeApplication object.

When system tray icons are supported, the icon will be of type SystemTrayIcon. Otherwise, the type of icon will be another subclass of InteractiveIcon, typically DockIcon.

Important: Attempting to call a SystemTrayIcon class method on the NativeApplication.icon object on an operating system for which AIR does not support system tray icons will generate a run-time exception.

Property Detail
AIR-only bitmapsproperty
bitmaps:Array  [read-write]

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
    public function get bitmaps():Array
    public function set bitmaps(value:Array):void
AIR-only heightproperty 
height:int  [read-only]

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
AIR-only menuproperty 
menu:NativeMenu  [read-write]

The system tray icon menu.


Implementation
    public function get menu():NativeMenu
    public function set menu(value:NativeMenu):void
AIR-only tooltipproperty 
tooltip:String  [read-write]

The tooltip that pops up for the system tray icon. If the string is longer than SystemTrayIcon.MAX_TIP_LENGTH, the tip will be truncated.


Implementation
    public function get tooltip():String
    public function set tooltip(value:String):void
AIR-only widthproperty 
width:int  [read-only]

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
