/**
- * @class Ext.layout.container.AbstractCard
- * @extends Ext.layout.container.Fit
- * <p>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.</p>
- * <p>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.</p>
- * <p>Containers that are configured with a card layout will have a method setActiveItem dynamically added to it.
- * <pre><code>
- var p = new Ext.panel.Panel({
- fullscreen: true,
- layout: 'card',
- items: [{
- html: 'Card 1'
- },{
- html: 'Card 2'
- }]
- });
- p.setActiveItem(1);
- </code></pre>
- * </p>
+ * Abstract base class for {@link Ext.layout.container.Card Card layout}.
+ * @private
