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 will be 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 when nothing has been assigned to the bitmaps property. In others, no icon will appear.

To set or change the icon appearance, assign an array containing the 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, set bitmaps to an empty array.

Note: When loading image files for an icon, the PNG file format generally provides the best alpha blending. The GIF format only supports 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
