+<p>This <code>Dial</code> widget example shows the following:</p>
+
+<ol>
+ <li>A demonstration of a large value range combined with fine increment control.</li>
+ <li>Setting UI strings before rendering</li>
+ <li>Setting configuration attributes</li>
+ <li>Construction-time event subscription allowing Dial to control an interactive UI</li>
+ <li>Calling one of Dial's value change methods from the click of a link. <code><a>Hubble</a></code></li>
+</ol>
+<p>Notice the Dial can traverse the entire 6,000+ pixels of the scene height, but by pulling the handle
+farther away from the Dial's center while rotating, the user can get 1 pixel movements, without strain.
+After the dial has focus, the following keys also opperate the Dial, arrow up/down/left/right, page up/down, home, end. The action of these keys can be controlled via <a href="index.html#attributes" title="YUI 3: Dial">Dial's configuration attributes</a>.</p>

+
+<p>The <code>valueChange</code> event of a <code>Dial</code> can be the means of controlling other UI displayed on a page.</p>
+
+<h4 id="the-markup">The Markup</h4>
+<p>
+<strong>Note:</strong> be sure to add the <code>yui3-skin-sam</code> classname to the
+page's <code><body></code> element or to a parent element of the widget in order to apply
+the default CSS skin. See <a href="http://yuilibrary.com/yui/docs/tutorials/skins/">Understanding Skinning</a>.
+</p>
+<pre class="code prettyprint"><body class="yui3-skin-sam"> <!-- You need this skin class --></pre>
+
+<p>The only markup requirement for the <code>Dial</code> itself is an element to contain the Dial.
+The rest of the markup and CSS in this example is just for the Hubble telescope visualization.
+</p>
+
+<pre class="code prettyprint"><div id="demo"></div></pre>
+
+
+<h4 id="the-javascript">The JavaScript</h4>
+
+<p>This example builds on previous examples by showing how to modify the visible UI strings before the dial renders.</p>
+
+<p>During instatiation of a Dial, several configuration attributes can be set (see the code-block below); note the construction-time event subscription:</p>
+
+<pre class="code prettyprint">YUI().use('dial', function(Y) {
+
+ var sceneH = Y.one('#scene').get('region').height,
+ subSea = 450,
+ viewFrameH = Y.one('#view_frame').get('region').height -2,
+ zeroPt = 100,
+ originY = -sceneH + subSea + viewFrameH - zeroPt;
+
+ Y.one('#scene').setStyle('top', originY + 'px');
+
+ /**
+ * The Dial's valueChange event is passed to this.
+ * sets the CSS top value of the pictoral scene of the earth to the hubble.
+ * This scene is an absolute positioned div inside another div with
+ * overflow set to hidden.
+ */
+ setSceneY = function(e) {
+ Y.one('#scene').setStyle('top', (originY + (e.newVal * 10)) + 'px');
+ }
+
+ var dial = new Y.Dial({
+ min:-35,
+ max:559,
+ stepsPerRevolution:30,
+ value: 0,
+ diameter: 100,
+ minorStep: 1,
+ majorStep: 10,
+ decimalPlaces: 2,
+ strings:{label:'Altitude in Kilometers:', resetStr: 'Reset', tooltipHandle: 'Drag to set'},
+ // construction-time event subscription
+ after : {
+ valueChange: Y.bind( setSceneY, dial )
+ }
+ });
+ dial.render('#demo');
+
+ // Function that calls a method in Dial that sets its value to the value of the max config attribute
+ // Other methods available include,
+ // _setToMin(), _resetDial(), _incrMinor(), _decrMinor(), _incrMajor(), _decrMajor(),
+ var setDialToMax = function(e){
+ e.preventDefault();
+ this._setToMax();
+ }
+
+ // Subscribe to the click of the "Hubble" anchor, passing the dial as the 'this'
+ Y.on('click', setDialToMax, '#a-hubble', dial);
+
+});</pre>
+
+
+
+<h5 id="the-event-handler">The Event Handler</h5>
+
+<p>
+Preceding the code that instantiates the <code>Dial</code> widget, declare the event handler.
+We can use the value of the <code>Dial</code> to do whatever we want, but
+in this example the event handler updates the CSS <code>top</code> property of the pictorial scene <code><div id="scene"></code> of Hubble's relationship to Earth.
+This scene is moved up or down inside a framing element <code><div class="viewframe"></code> that has CSS <code>overflow:hidden;</code>.
+The reason <code>e.newVal</code> is multiplied by <code>10</code> is so that the scene moves 10px for every 1 kilometer of the <code>Dial</code>'s value.
+</p>
+
+
+
+<pre class="code prettyprint">/**
+* The Dial's valueChange event is passed to this.
+* sets the CSS top value of the pictoral scene of the earth to the hubble.
+* This scene is an absolute positioned div inside another div with
+* overflow set to hidden.
+*/
+setSceneY = function(e) {
+ Y.one('#scene').setStyle('top', (originY + (e.newVal * 10)) + 'px');
