14  * @class Roo.SplitBar
15  * @extends Roo.util.Observable
16  * Creates draggable splitter bar functionality from two elements (element to be dragged and element to be resized).
17  * &lt;br&gt;&lt;br&gt;
18  * Usage:
19  * &lt;pre&gt;&lt;code&gt;
20 var split = new Roo.SplitBar(&quot;elementToDrag&quot;, &quot;elementToSize&quot;,
21                    Roo.SplitBar.HORIZONTAL, Roo.SplitBar.LEFT);
22 split.setAdapter(new Roo.SplitBar.AbsoluteLayoutAdapter(&quot;container&quot;));
23 split.minSize = 100;
24 split.maxSize = 600;
25 split.animate = true;
26 split.on('moved', splitterMoved);
27 &lt;/code&gt;&lt;/pre&gt;
28  * @constructor
29  * Create a new SplitBar
30  * @param {String/HTMLElement/Roo.Element} dragElement The element to be dragged and act as the SplitBar. 
31  * @param {String/HTMLElement/Roo.Element} resizingElement The element to be resized based on where the SplitBar element is dragged 
32  * @param {Number} orientation (optional) Either Roo.SplitBar.HORIZONTAL or Roo.SplitBar.VERTICAL. (Defaults to HORIZONTAL)
33  * @param {Number} placement (optional) Either Roo.SplitBar.LEFT or Roo.SplitBar.RIGHT for horizontal or  
34                         Roo.SplitBar.TOP or Roo.SplitBar.BOTTOM for vertical. (By default, this is determined automatically by the initial
35                         position of the SplitBar).
