/**
 * @aside video tabs-toolbars
 *
 * {@link Ext.Toolbar}s are most commonly used as docked items as within a {@link Ext.Container}. They can be docked either `top` or `bottom` using the {@link #docked} configuration.
 *
 * They allow you to insert items (normally {@link Ext.Button buttons}) and also add a {@link #title}.
 *
 * The {@link #defaultType} of {@link Ext.Toolbar} is {@link Ext.Button}.
 *
 * You can alternatively use {@link Ext.TitleBar} if you want the title to automatically adjust the size of its items.
 *
 * ## Examples
 *
 *     @example miniphone preview
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: {
 *             type: 'vbox',
 *             pack: 'center'
 *         },
 *         items: [
 *             {
 *                 xtype : 'toolbar',
 *                 docked: 'top',
 *                 title: 'My Toolbar'
 *             },
 *             {
 *                 xtype: 'container',
 *                 defaults: {
 *                     xtype: 'button',
 *                     margin: '10 10 0 10'
 *                 },
 *                 items: [
 *                     {
 *                         text: 'Toggle docked',
 *                         handler: function() {
 *                             var toolbar = Ext.ComponentQuery.query('toolbar')[0],
 *                                 newDocked = (toolbar.getDocked() === 'top') ? 'bottom' : 'top';
 *
 *                             toolbar.setDocked(newDocked);
 *                         }
 *                     },
 *                     {
 *                         text: 'Toggle UI',
 *                         handler: function() {
 *                             var toolbar = Ext.ComponentQuery.query('toolbar')[0],
 *                                 newUi = (toolbar.getUi() === 'light') ? 'dark' : 'light';
 *
 *                             toolbar.setUi(newUi);
 *                         }
 *                     },
 *                     {
 *                         text: 'Change title',
 *                         handler: function() {
 *                             var toolbar = Ext.ComponentQuery.query('toolbar')[0],
 *                                 titles = ['My Toolbar', 'Ext.Toolbar', 'Configurations are awesome!', 'Beautiful.'],
                                   //internally, the title configuration gets converted into a {@link Ext.Title} component,
                                   //so you must get the title configuration of that component
 *                                 title = toolbar.getTitle().getTitle(),
 *                                 newTitle = titles[titles.indexOf(title) + 1] || titles[0];
 *
 *                             toolbar.setTitle(newTitle);
 *                         }
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * ## Notes
 *
 * You must use a HTML5 doctype for {@link #docked} `bottom` to work. To do this, simply add the following code to the HTML file:
 *
 *     <!doctype html>
 *
 * So your index.html file should look a little like this:
 *
 *     <!doctype html>
 *     <html>
 *         <head>
 *             <title>MY application title</title>
 *             ...
 *
