-</span> * This layout manages multiple child Components, each is fit to the Container, where only a single child Component
- * can be visible at any given time. This layout style is most commonly used for wizards, tab implementations, etc.
- * This class is intended to be extended or created via the layout:'card' {@link Ext.container.Container#layout} config,
- * and should generally not need to be created directly via the new keyword.
- *
- * The CardLayout's focal method is {@link #setActiveItem}. Since only one panel is displayed at a time,
- * the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of
- * the next panel to display. The layout itself does not provide a user interface for handling this navigation,
- * so that functionality must be provided by the developer.
- *
- * Containers that are configured with a card layout will have a method setActiveItem dynamically added to it.
- *
- * var p = new Ext.panel.Panel({
- * fullscreen: true,
- * layout: 'card',
- * items: [{
- * html: 'Card 1'
- * },{
- * html: 'Card 2'
- * }]
- * });
- * p.setActiveItem(1);
