+ * <b><tt>{@link #anchor}</tt></b> rules.</p>
+ * <p>This class is intended to be extended or created via the layout:'anchor' {@link Ext.Container#layout}
+ * config, and should generally not need to be created directly via the new keyword.</p>
+ * <p>AnchorLayout does not have any direct config options (other than inherited ones). By default,
+ * AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the
+ * container using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.
+ * If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating
+ * anchor measurements based on it instead, allowing the container to be sized independently of the anchoring
+ * logic if necessary. For example:</p>
+ * <pre><code>
+var viewport = new Ext.Viewport({
+ layout:'anchor',
+ anchorSize: {width:800, height:600},
+ items:[{
+ title:'Item 1',
