To display the cursor, use the Mouse.registerCursor() function. To return
control of the cursor image to the operating system, call Mouse.unregisterCursor().
Call Mouse.supportsNativeCursor to test whether native cursors are supported on the
current computer.
The maximum cursor size is 32x32 pixels.Transparency is supported on most operating systems.
A native mouse cursor is implemented directly through the operating system cursor mechanism
and is a more efficient means for displaying a custom cursor image than using a display object.
You can animate the cursor by supplying more than one image in the data property
and setting the frame rate.
The cursor is only displayed within the bounds of the stage. Outside the stage, control of the cursor image returns to the operating system

data:Vector.<BitmapData>| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.2, AIR 2.6 |
A Vector of BitmapData objects containing the cursor image or images.
Supply more than one image and set the framerate property to
animate the cursor.
The maximum cursor size is 32x32 pixels.
Implementation
public function get data():Vector.<BitmapData> public function set data(value:Vector.<BitmapData>):voidframeRate | property |
frameRate:Number| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.2, AIR 2.6 |
The frame rate for animating the cursor.
Suppy more than one image in the data property and set the
frame rate to a value greater than 0 to animate the cursor. The cursor frame rate
may differ from the current SWF frame rate.
Implementation
public function get frameRate():Number public function set frameRate(value:Number):voidhotSpot | property |
hotSpot:Point| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.2, AIR 2.6 |
The hot spot of the cursor in pixels.
The hotspot is the point on the cursor under which mouse clicks are registered. By default, the hot spot is the upper-left corner (0,0).
Implementation
public function get hotSpot():Point public function set hotSpot(value:Point):voidMouseCursorData | () | Constructor |
public function MouseCursorData()| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.2, AIR 2.6 |
Creates a MouseCursorData object.
To display the cursor, call the Mouse.registerCursor() function.

The example uses the drawing commands available through the Graphics class to create
eight, rotated images of an arrow. These images are pushed into a vector and assigned to the data
property of the MouseCursorData object. (Note that you can also use prerendered bitmap images for your cursors.)
