+/**
+ * @class Ext.slider.Tip
+ * @extends Ext.tip.Tip
+ * Simple plugin for using an Ext.tip.Tip with a slider to show the slider value. In general this
+ * class is not created directly, instead pass the {@link Ext.slider.Multi#useTips} and 
+ * {@link Ext.slider.Multi#tipText} configuration options to the slider directly.
+ * {@img Ext.slider.Tip/Ext.slider.Tip1.png Ext.slider.Tip component}
+ * Example usage:
+<pre>
+    Ext.create('Ext.slider.Single', {
+        width: 214,
+        minValue: 0,
+        maxValue: 100,
+        useTips: true,
+        renderTo: Ext.getBody()
+    });   
+</pre>
+ * Optionally provide your own tip text by passing tipText:
+ <pre>
+ new Ext.slider.Single({
+     width: 214,
+     minValue: 0,
+     maxValue: 100,
+     useTips: true,
+     tipText: function(thumb){
+         return Ext.String.format('<b>{0}% complete</b>', thumb.value);
+     }
+ });
+ </pre>
+ * @xtype slidertip
+ */
