Inheritance	Icon EventDispatcher

Runtime Versions:

The Icon class represents an operating system icon.

An Icon object has one property, bitmaps, which is an array of BitmapData objects. Only one image is displayed at a time. The operating system selects the image closest in size to the icon's current display size, scaling if necessary.

Property Detail

bitmaps

property

bitmaps:Array

Runtime Versions:

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.
