/**
 * @class Ext.Toolbar
 * @extends Ext.Container
 * <p>Basic Toolbar class. Although the <tt>{@link Ext.Container#defaultType defaultType}</tt> for Toolbar
 * is <tt>{@link Ext.Button button}</tt>, Toolbar elements (child items for the Toolbar container) may
 * be virtually any type of Component. Toolbar elements can be created explicitly via their constructors,
 * or implicitly via their xtypes, and can be <tt>{@link #add}</tt>ed dynamically.</p>
 * <p>Some items have shortcut strings for creation:</p>
 * <pre>
<u>Shortcut</u>  <u>xtype</u>          <u>Class</u>                  <u>Description</u>
'->'      'tbfill'       {@link Ext.Toolbar.Fill}       begin using the right-justified button container
'-'       'tbseparator'  {@link Ext.Toolbar.Separator}  add a vertical separator bar between toolbar items
' '       'tbspacer'     {@link Ext.Toolbar.Spacer}     add horiztonal space between elements
 * </pre>
 *
 * Example usage of various elements:
 * <pre><code>
var tb = new Ext.Toolbar({
    renderTo: document.body,
    width: 600,
    height: 100,
    items: [
        {
            // xtype: 'button', // default for Toolbars, same as 'tbbutton'
            text: 'Button'
        },
        {
            xtype: 'splitbutton', // same as 'tbsplitbutton'
            text: 'Split Button'
        },
        // begin using the right-justified button container
        '->', // same as {xtype: 'tbfill'}, // Ext.Toolbar.Fill
        {
            xtype: 'textfield',
            name: 'field1',
            emptyText: 'enter search term'
        },
        // add a vertical separator bar between toolbar items
        '-', // same as {xtype: 'tbseparator'} to create Ext.Toolbar.Separator
        'text 1', // same as {xtype: 'tbtext', text: 'text1'} to create Ext.Toolbar.TextItem
        {xtype: 'tbspacer'},// same as ' ' to create Ext.Toolbar.Spacer
        'text 2',
        {xtype: 'tbspacer', width: 50}, // add a 50px space
        'text 3'
    ]
});
 * </code></pre>
 * Example adding a ComboBox within a menu of a button:
 * <pre><code>
// ComboBox creation
var combo = new Ext.form.ComboBox({
    store: new Ext.data.ArrayStore({
        autoDestroy: true,
        fields: ['initials', 'fullname'],
        data : [
            ['FF', 'Fred Flintstone'],
            ['BR', 'Barney Rubble']
        ]
    }),
    displayField: 'fullname',
    typeAhead: true,
    mode: 'local',
    forceSelection: true,
    triggerAction: 'all',
    emptyText: 'Select a name...',
    selectOnFocus: true,
    width: 135,
    getListParent: function() {
        return this.el.up('.x-menu');
    },
    iconCls: 'no-icon' //use iconCls if placing within menu to shift to right side of menu
});

// put ComboBox in a Menu
var menu = new Ext.menu.Menu({
    id: 'mainMenu',
    items: [
        combo // A Field in a Menu
    ]
});

// add a Button with the menu
tb.add({
        text:'Button w/ Menu',
        menu: menu  // assign menu by instance
    });
