/**
+ * @class Ext.panel.Panel
+ * @extends Ext.panel.AbstractPanel
+ * <p>Panel is a container that has specific functionality and structural components that make
+ * it the perfect building block for application-oriented user interfaces.</p>
+ * <p>Panels are, by virtue of their inheritance from {@link Ext.container.Container}, capable
+ * of being configured with a {@link Ext.container.Container#layout layout}, and containing child Components.</p>
+ * <p>When either specifying child {@link Ext.Component#items items} of a Panel, or dynamically {@link Ext.container.Container#add adding} Components
+ * to a Panel, remember to consider how you wish the Panel to arrange those child elements, and whether
+ * those child elements need to be sized using one of Ext's built-in <code><b>{@link Ext.container.Container#layout layout}</b></code> schemes. By
+ * default, Panels use the {@link Ext.layout.container.Auto Auto} scheme. This simply renders
+ * child components, appending them one after the other inside the Container, and <b>does not apply any sizing</b>
+ * at all.</p>
+ * {@img Ext.panel.Panel/panel.png Panel components}
+ * <p>A Panel may also contain {@link #bbar bottom} and {@link #tbar top} toolbars, along with separate
+ * {@link #header}, {@link #footer} and {@link #body} sections (see {@link #frame} for additional
+ * information).</p>
+ * <p>Panel also provides built-in {@link #collapsible collapsible, expandable} and {@link #closable} behavior.
+ * Panels can be easily dropped into any {@link Ext.container.Container Container} or layout, and the
+ * layout and rendering pipeline is {@link Ext.container.Container#add completely managed by the framework}.</p>
+ * <p><b>Note:</b> By default, the <code>{@link #closable close}</code> header tool <i>destroys</i> the Panel resulting in removal of the Panel
+ * and the destruction of any descendant Components. This makes the Panel object, and all its descendants <b>unusable</b>. To enable the close
+ * tool to simply <i>hide</i> a Panel for later re-use, configure the Panel with <b><code>{@link #closeAction closeAction: 'hide'}</code></b>.</p>
+ * <p>Usually, Panels are used as constituents within an application, in which case, they would be used as child items of Containers,
+ * and would themselves use Ext.Components as child {@link #items}. However to illustrate simply rendering a Panel into the document,
+ * here's how to do it:<pre><code>
+Ext.create('Ext.panel.Panel', {
+ title: 'Hello',
+ width: 200,
+ html: '<p>World!</p>',
+ renderTo: document.body
+});
+</code></pre></p>
+ * <p>A more realistic scenario is a Panel created to house input fields which will not be rendered, but used as a constituent part of a Container:<pre><code>
+var filterPanel = Ext.create('Ext.panel.Panel', {
+ bodyPadding: 5, // Don't want content to crunch against the borders
+ title: 'Filters',
+ items: [{
+ xtype: 'datefield',
+ fieldLabel: 'Start date'
+ }, {
+ xtype: 'datefield',
+ fieldLabel: 'End date'
+ }]
+});
+</code></pre></p>
+ * <p>Note that the Panel above is not configured to render into the document, nor is it configured with a size or position. In a real world scenario,
+ * the Container into which the Panel is added will use a {@link #layout} to render, size and position its child Components.</p>
+ * <p>Panels will often use specific {@link #layout}s to provide an application with shape and structure by containing and arranging child
+ * Components: <pre><code>
+var resultsPanel = Ext.create('Ext.panel.Panel', {
+ title: 'Results',
+ width: 600,
+ height: 400,
+ renderTo: document.body,
+ layout: {
+ type: 'vbox', // Arrange child items vertically
+ align: 'stretch', // Each takes up full width
+ padding: 5
+ },
+ items: [{ // Results grid specified as a config object with an xtype of 'grid'
+ xtype: 'grid',
+ columns: [{header: 'Column One'}], // One header just for show. There's no data,
+ store: Ext.create('Ext.data.ArrayStore', {}), // A dummy empty data store
+ flex: 1 // Use 1/3 of Container's height (hint to Box layout)
+ }, {
+ xtype: 'splitter' // A splitter between the two child items
+ }, { // Details Panel specified as a config object (no xtype defaults to 'panel').
+ title: 'Details',
+ bodyPadding: 5,
+ items: [{
+ fieldLabel: 'Data item',
+ xtype: 'textfield'
+ }], // An array of form fields
+ flex: 2 // Use 2/3 of Container's height (hint to Box layout)
+ }]
+});
+</code></pre>
+ * The example illustrates one possible method of displaying search results. The Panel contains a grid with the resulting data arranged
+ * in rows. Each selected row may be displayed in detail in the Panel below. The {@link Ext.layout.container.VBox vbox} layout is used
+ * to arrange the two vertically. It is configured to stretch child items horizontally to full width. Child items may either be configured
+ * with a numeric height, or with a <code>flex</code> value to distribute available space proportionately.</p>
+ * <p>This Panel itself may be a child item of, for exaple, a {@link Ext.tab.Panel} which will size its child items to fit within its
+ * content area.</p>
+ * <p>Using these techniques, as long as the <b>layout</b> is chosen and configured correctly, an application may have any level of
+ * nested containment, all dynamically sized according to configuration, the user's preference and available browser size.</p>
