The @ax-student-ar-fl-controls-Button component represents a commonly used rectangular button. @ax-student-ar-fl-controls-Button components display a text label, an icon, or both. <p>A @ax-student-ar-fl-controls-Button component is typically associated with an event handler method that listens for a <code>click</code> event and performs the specified task after the <code>click</code> event is dispatched. When the user clicks an enabled button, the button dispatches the <code>click</code> and <code>buttonDown</code> events. Even if it is not enabled, a button dispatches other events including <code>mouseMove</code>, <code>mouseOver</code>, <code>mouseOut</code>, <code>rollOver</code>, <code>rollOut</code>, <code>mouseDown</code>, and <code>mouseUp</code>.</p> <p>You can change the appearance of the button by associating a different skin with each button state. A @ax-student-ar-fl-controls-Button component can also be set to function as a push button or a toggle button. </p> @langversion 3.0 @playerversion Flash 9.0.28.0 @includeExample examples/@fileExample.as
