-/**\r
- * @class Ext.layout.AnchorLayout\r
- * @extends Ext.layout.ContainerLayout\r
- * <p>This is a layout that enables anchoring of contained elements relative to the container's dimensions.\r
- * If the container is resized, all anchored items are automatically rerendered according to their\r
- * <b><tt>{@link #anchor}</tt></b> rules.</p>\r
- * <p>This class is intended to be extended or created via the layout:'anchor' {@link Ext.Container#layout}\r
- * config, and should generally not need to be created directly via the new keyword.</p>\r
- * <p>AnchorLayout does not have any direct config options (other than inherited ones). By default,\r
- * AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the\r
- * container using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.\r
- * If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating\r
- * anchor measurements based on it instead, allowing the container to be sized independently of the anchoring\r
- * logic if necessary. For example:</p>\r
- * <pre><code>\r
-var viewport = new Ext.Viewport({\r
- layout:'anchor',\r
- anchorSize: {width:800, height:600},\r
- items:[{\r
- title:'Item 1',\r
- html:'Content 1',\r
- width:800,\r
- anchor:'right 20%'\r
- },{\r
- title:'Item 2',\r
- html:'Content 2',\r
- width:300,\r
- anchor:'50% 30%'\r
- },{\r
- title:'Item 3',\r
- html:'Content 3',\r
- width:600,\r
- anchor:'-100 50%'\r
- }]\r
-});\r
- * </code></pre>\r
- */\r
-Ext.layout.AnchorLayout = Ext.extend(Ext.layout.ContainerLayout, {\r
- /**\r
- * @cfg {String} anchor\r
- * <p>This configuation option is to be applied to <b>child <tt>items</tt></b> of a container managed by\r
- * this layout (ie. configured with <tt>layout:'anchor'</tt>).</p><br/>\r
- * \r
- * <p>This value is what tells the layout how an item should be anchored to the container. <tt>items</tt>\r
- * added to an AnchorLayout accept an anchoring-specific config property of <b>anchor</b> which is a string\r
- * containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').\r
- * The following types of anchor values are supported:<div class="mdetail-params"><ul>\r
- * \r
- * <li><b>Percentage</b> : Any value between 1 and 100, expressed as a percentage.<div class="sub-desc">\r
- * The first anchor is the percentage width that the item should take up within the container, and the\r
- * second is the percentage height. For example:<pre><code>\r
-// two values specified\r
-anchor: '100% 50%' // render item complete width of the container and\r
- // 1/2 height of the container\r
-// one value specified\r
-anchor: '100%' // the width value; the height will default to auto\r
- * </code></pre></div></li>\r
- * \r
- * <li><b>Offsets</b> : Any positive or negative integer value.<div class="sub-desc">\r
- * This is a raw adjustment where the first anchor is the offset from the right edge of the container,\r
- * and the second is the offset from the bottom edge. For example:<pre><code>\r
-// two values specified\r
-anchor: '-50 -100' // render item the complete width of the container\r
- // minus 50 pixels and\r
- // the complete height minus 100 pixels.\r
-// one value specified\r
-anchor: '-50' // anchor value is assumed to be the right offset value\r
- // bottom offset will default to 0\r
- * </code></pre></div></li>\r
- * \r
- * <li><b>Sides</b> : Valid values are <tt>'right'</tt> (or <tt>'r'</tt>) and <tt>'bottom'</tt>\r
- * (or <tt>'b'</tt>).<div class="sub-desc">\r
- * Either the container must have a fixed size or an anchorSize config value defined at render time in\r
- * order for these to have any effect.</div></li>\r
- *\r
- * <li><b>Mixed</b> : <div class="sub-desc">\r
- * Anchor values can also be mixed as needed. For example, to render the width offset from the container\r
- * right edge by 50 pixels and 75% of the container's height use:\r
- * <pre><code>\r
-anchor: '-50 75%' \r
- * </code></pre></div></li>\r
- * \r
- * \r
- * </ul></div>\r
