-/**
- * @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.
- * 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 anchorSize.
- * 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:
- *
-var viewport = new Ext.Viewport({
- layout:'anchor',
- anchorSize: {width:800, height:600},
- items:[{
- title:'Item 1',
- html:'Content 1',
- width:800,
- anchor:'right 20%'
- },{
- title:'Item 2',
- html:'Content 2',
- width:300,
- anchor:'50% 30%'
- },{
- title:'Item 3',
- html:'Content 3',
- width:600,
- anchor:'-100 50%'
- }]
-});
- *
