Examples How to use this example

LinkStateExample.as

This example adds event listeners to a LinkElement to listen for the following mouse events: CLICK, MOUSE_DOWN, MOUSE_OUT, ROLL_OVER, ROLL_OUT. When one of these events occurs, the example checks to see if the link is in the hover state. If so, it displays the event type and linkState value.
