/**

 * @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>

    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({

// add a Button with the menu

 * <p>Paging is typically handled on the server side (see exception below). The client sends
 * parameters to the server side, which the server needs to interpret and then respond with the

 * and provides automatic paging control. This Component {@link Ext.data.Store#load load}s blocks
 * of data into the <tt>{@link #store}</tt> by passing {@link Ext.data.Store#paramNames paramNames} used for
 * paging criteria.</p>
 * <p>PagingToolbar is typically used as one of the Grid's toolbars:</p>
 * <pre><code>
Ext.QuickTips.init(); // to display button quicktips

var myStore = new Ext.data.Store({
    ...
});

var myPageSize = 25;  // server script should only send back 25 items

            'text 1'
        ]
    })
});
 * </code></pre>
 *
 * <p>To use paging, pass the paging requirements to the server when the store is first loaded.</p>
 * <pre><code>
store.load({
    params: {
