/**
|
|
* @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'
|
|
]
|
|
});
|

|
|
* Note: if there are more records/rows than can be viewed in the available screen area, vertical

|
|
* <p>Paging is typically handled on the server side (see exception below). The client sends

})
|
|
});
|
|
* </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: {
|
|
// specify params for the first page load if using paging

|
foo: 'bar'

});
|

var myStore = new Ext.data.Store({

{@link Ext.data.Store#autoLoad autoLoad}: {params:{start: 0, limit: 25}},
|
|
...
|
|
});
|
|
* </code></pre>
|
|
*
|
|
* <p>The packet sent back from the server would have this form:</p>
|
|
* <pre><code>
|
