-<p>Provides automatic scrolling of overflow regions in the page during drag operations.</p>
-<p>The ScrollManager configs will be used as the defaults for any scroll container registered with it,
-but you can also override most of the configs per scroll container by adding a
-<tt>ddScrollConfig</tt> object to the target element that contains these properties: <a ext:cls="Ext.dd.ScrollManager" ext:member="hthresh" href="output/Ext.dd.ScrollManager.html#hthresh">hthresh</a>,
-<a ext:cls="Ext.dd.ScrollManager" ext:member="vthresh" href="output/Ext.dd.ScrollManager.html#vthresh">vthresh</a>, <a ext:cls="Ext.dd.ScrollManager" ext:member="increment" href="output/Ext.dd.ScrollManager.html#increment">increment</a> and <a ext:cls="Ext.dd.ScrollManager" ext:member="frequency" href="output/Ext.dd.ScrollManager.html#frequency">frequency</a>. Example usage:
-<pre><code>var el = Ext.get(<em>'scroll-ct'</em>);
-el.ddScrollConfig = {
- vthresh: 50,
- hthresh: -1,
- frequency: 100,
- increment: 200
-};
-Ext.dd.ScrollManager.register(el);</code></pre>
