     * @class Ext.Toolbar
     * @extends Ext.Container
     * Basic Toolbar class. Although the {@link Ext.Container#defaultType defaultType} for Toolbar
     * is {@link Ext.Button button}, 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 {@link #add}ed dynamically.
     * Some items have shortcut strings for creation:
     *
    Shortcut  xtype          Class                  Description
    '->'      '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
     *
     *
     * Example usage of various elements:
     *
    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'
        ]
    });
     *
     * Example adding a ComboBox within a menu of a button:
     *
    // ComboBox creation
    var combo = new Ext.form.ComboBox({
        store: new Ext.data.ArrayStore({
            autoDestroy: true,

        displayField: 'fullname',
        typeAhead: true,
        mode: 'local',
        forceSelection: true,
        triggerAction: 'all',
        emptyText: 'Select a name...',
        selectOnFocus: true,
        width: 135,
        getListParent: function() {
