<div class="description">
<p>Create a new <code>Button</code> object. A Button is a special type of Sprite that is set-up to handle Pointer events automatically. The four states a Button responds to are:
'Over' - when the Pointer moves over the Button. This is also commonly known as 'hover'.
'Out' - when the Pointer that was previously over the Button moves out of it.
'Down' - when the Pointer is pressed down on the Button. I.e. touched on a touch enabled device or clicked with the mouse.
'Up' - when the Pointer that was pressed down on the Button is released again.
You can set a unique texture frame and Sound for any of these states.</p>
