- * @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
- });
- tb.doLayout();
