+</span> * This layout manages multiple child Components, each fitted 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,
+ * the only way to move from one Component to the next is by calling setActiveItem, passing the next panel to display
+ * (or its id or index). The layout itself does not provide a user interface for handling this navigation,
* so that functionality must be provided by the developer.
*
+ * To change the active card of a container, call the setActiveItem method of its layout:
+ *
+ * Ext.create('Ext.panel.Panel', {
+ * layout: 'card',
+ * items: [
+ * { html: 'Card 1' },
+ * { html: 'Card 2' }
+ * ],
+ * renderTo: Ext.getBody()
+ * });
+ *
+ * p.getLayout().setActiveItem(1);
+ *
* In the following example, a simplistic wizard setup is demonstrated. A button bar is added
* to the footer of the containing panel to provide navigation buttons. The buttons will be handled by a
* common navigation routine. Note that other uses of a CardLayout (like a tab control) would require a
* completely different implementation. For serious implementations, a better approach would be to extend
* CardLayout to provide the custom functionality needed.

- * Example usage:
- *
+ * @example
* var navigate = function(panel, direction){
* // This routine could contain business logic required to manage the navigation steps.
* // It would call setActiveItem as needed, manage navigation button state, handle any
* Ext.getCmp('move-prev').setDisabled(!layout.getPrev());
* Ext.getCmp('move-next').setDisabled(!layout.getNext());
* };

* Ext.create('Ext.panel.Panel', {
* title: 'Example Wizard',
* width: 300,
* height: 200,
* layout: 'card',
- * activeItem: 0, // make sure the active item is set on the container config!
* bodyStyle: 'padding:15px',
* defaults: {
* // applied to each contained panel
* html: '<h1>Congratulations!</h1><p>Step 3 of 3 - Complete</p>'
