<span class="c">* @module button</span>
<span class="c">* @description <p>The Button Control enables the creation of rich, graphical </span>
<span class="c">* buttons that function like traditional HTML form buttons. <em>Unlike</em> </span>
<span class="c">* traditional HTML form buttons, buttons created with the Button Control can have </span>
<span class="c">* a label that is different from its value. With the inclusion of the optional </span>
<span class="c">* <a href="module_menu.html">Menu Control</a>, the Button Control can also be</span>
<span class="c">* used to create menu buttons and split buttons, controls that are not </span>
<span class="c">* available natively in HTML. The Button Control can also be thought of as a </span>
<span class="c">* way to create more visually engaging implementations of the browser's </span>
<span class="c">* default radio-button and check-box controls.</p></span>
<span class="c">* <p>The Button Control supports the following types:</p></span>
<span class="c">* <dl></span>
<span class="c">* <dt>push</dt></span>
<span class="c">* <dd>Basic push button that can execute a user-specified command when </span>
<span class="c">* pressed.</dd></span>
<span class="c">* <dt>link</dt></span>
<span class="c">* <dd>Navigates to a specified url when pressed.</dd></span>
<span class="c">* <dt>submit</dt></span>
<span class="c">* <dd>Submits the parent form when pressed.</dd></span>
<span class="c">* <dt>reset</dt></span>
<span class="c">* <dd>Resets the parent form when pressed.</dd></span>
<span class="c">* <dt>checkbox</dt></span>
<span class="c">* <dd>Maintains a "checked" state that can be toggled on and off.</dd></span>
<span class="c">* <dt>radio</dt></span>
<span class="c">* <dd>Maintains a "checked" state that can be toggled on and off. Use with </span>
<span class="c">* the ButtonGroup class to create a set of controls that are mutually </span>
<span class="c">* exclusive; checking one button in the set will uncheck all others in </span>
<span class="c">* the group.</dd></span>
<span class="c">* <dt>menu</dt></span>
<span class="c">* <dd>When pressed will show/hide a menu.</dd></span>
