Animate busy cursor in flex?

I find out how to replace the busy cursor h开发者_JAVA百科ere: http://livedocs.adobe.com/flex/3/html/cursormgr_3.html

However, how do you animate an image for the cursor?

---

Use an animated asset created in the Flash IDE and embed it within your Flex app.

You can also create them programmatically, e.g. by extending flash.display.Sprite:

Class SampleCursor:

public class SampleCursor extends Sprite
    public function SampleCursor() {
        addEventListener(Event.ENTER_FRAME, drawCursor);
    }

    public function drawCursor(e:Event):void {
        // Draw cursor using graphics context
        // ...
    }
{

And in your Application you just register this class as a cursor (same for other types of cursors like bitmap or flash assets):

cursorManager.removeAllCursors();
cursorManager.setCursor(SampleCursor);

Hope that helps.
