/** - * @class Ext.layout.AnchorLayout - * @extends Ext.layout.ContainerLayout - *- + + + +This is a layout that enables anchoring of contained elements relative to the container's dimensions. - * If the container is resized, all anchored items are automatically rerendered according to their - * {@link #anchor} rules.
- *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.
