Here the Class we got to use is CusrsorManager and some methods in it.
The following example shows the custom cursor on a Flex App.

public static const loaderCursor:Class;
var cursorId:int = CursorManager.setCursor(loaderCursor);
The code will set the cursor ,to remove it use the line of code.
CursorManager.removeCursor(cursorId);
Thats it the default cursor is changed.
