-/**\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. If\r
- * the container is resized, all anchored items are automatically rerendered according to their anchor rules.\r
- * This class is intended to be extended or created via the layout:'anchor' {@link Ext.Container#layout} config,\r
- * 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). However, the container\r
- * using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>. By default,\r
- * AnchorLayout will calculate anchor measurements based on the size of the container itself. However, if\r
- * anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating anchor\r
- * measurements based on it instead, allowing the container to be sized independently of the anchoring logic if necessary.</p>\r
- * <p>The items added to an AnchorLayout can also supply an anchoring-specific config property of <b>anchor</b> which\r
- * is a string containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').\r
- * This value is what tells the layout how the item should be anchored to the container. The following types of\r
- * anchor values are supported:\r
- * <ul>\r
- * <li><b>Percentage</b>: Any value between 1 and 100, expressed as a percentage. The first anchor is the percentage\r
- * width that the item should take up within the container, and the second is the percentage height. Example: '100% 50%'\r
- * would render an item the complete width of the container and 1/2 its height. If only one anchor value is supplied\r
- * it is assumed to be the width value and the height will default to auto.</li>\r
- * <li><b>Offsets</b>: Any positive or negative integer value. The first anchor is the offset from the right edge of\r
- * the container, and the second is the offset from the bottom edge. Example: '-50 -100' would render an item the\r
- * complete width of the container minus 50 pixels and the complete height minus 100 pixels. If only one anchor value\r
- * is supplied it is assumed to be the right offset value and the bottom offset will default to 0.</li>\r
- * <li><b>Sides</b>: Valid values are 'right' (or 'r') and 'bottom' (or 'b'). Either the container must have a fixed\r
- * size or an anchorSize config value defined at render time in order for these to have any effect.</li>\r
- * </ul>\r
- * <p>Anchor values can also be mixed as needed. For example, '-50 75%' would render the width offset from the\r
- * container right edge by 50 pixels and 75% of the container's height.</p>\r
