By default, Flex uses the system cursor as the application cursor. You control the system cursor by using the settings of your operating system.
The Flex Cursor Manager lets you control the cursor image in your Flex application. For example, if your application performs processing that requires the user to wait until the processing completes, you can change the cursor so that it reflects the waiting period. In this case, you can change the cursor to an hourglass or other image.
You also can change the cursor to provide feedback to the user to indicate the actions that the user can perform. For example, you can use one cursor image to indicate that user input is enabled, and another to indicate that input is disabled.
You can use a JPEG, GIF, PNG, or SVG image, a Sprite object, or a SWF file as the cursor image.
