/**
* Basic Toolbar class. Although the {@link Ext.container.Container#defaultType defaultType} for
* Toolbar is {@link Ext.button.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 #method-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 horizontal space between elements
*
* @example
* Ext.create('Ext.toolbar.Toolbar', {
* renderTo: document.body,
* width : 500,
* items: [
* {
* // xtype: 'button', // default for Toolbars
* text: 'Button'
* },
* {
* xtype: 'splitbutton',
* text : 'Split Button'
* },
* // begin using the right-justified button container
* '->', // same as { xtype: 'tbfill' }
* {
* 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'
* ]
* });
*
* Toolbars have {@link #method-enable} and {@link #method-disable} methods which when called, will
* enable/disable all items within your toolbar.
*
* @example
* Ext.create('Ext.toolbar.Toolbar', {
* renderTo: document.body,
* width : 400,
* items: [
* {
* text: 'Button'
* },
* {
* xtype: 'splitbutton',
* text : 'Split Button'
* },
* '->',
* {
* xtype : 'textfield',
* name : 'field1',
* emptyText: 'enter search term'
* }
* ]
* });
*
* Example
*
* @example
* var enableBtn = Ext.create('Ext.button.Button', {
* text : 'Enable All Items',
* disabled: true,
* scope : this,
* handler : function() {
* //disable the enable button and enable the disable button
* enableBtn.disable();
* disableBtn.enable();
*
* //enable the toolbar
* toolbar.enable();
* }
* });
*
* var disableBtn = Ext.create('Ext.button.Button', {
* text : 'Disable All Items',
* scope : this,
* handler : function() {
* //enable the enable button and disable button
* disableBtn.disable();
* enableBtn.enable();
*
* //disable the toolbar
* toolbar.disable();
* }
* });
*
* var toolbar = Ext.create('Ext.toolbar.Toolbar', {
* renderTo: document.body,
* width : 400,
* margin : '5 0 0 0',
* items : [enableBtn, disableBtn]
* });
*
* Adding items to and removing items from a toolbar is as simple as calling the {@link #method-add}
* and {@link #method-remove} methods. There is also a {@link #removeAll} method
* which remove all items within the toolbar.
*
* @example
* var toolbar = Ext.create('Ext.toolbar.Toolbar', {
* renderTo: document.body,
* width : 700,
* items: [
* {
* text: 'Example Button'
* }
* ]
* });
*
* var addedItems = [];
*
* Ext.create('Ext.toolbar.Toolbar', {
* renderTo: document.body,
* width : 700,
* margin : '5 0 0 0',
* items : [
* {
* text : 'Add a button',
* scope : this,
* handler: function() {
* var text = prompt('Please enter the text for your button:');
* addedItems.push(toolbar.add({
* text: text
* }));
* }
* },
* {
* text : 'Add a text item',
* scope : this,
* handler: function() {
* var text = prompt('Please enter the text for your item:');
* addedItems.push(toolbar.add(text));
* }
* },
* {
* text : 'Add a toolbar separator',
* scope : this,
* handler: function() {
* addedItems.push(toolbar.add('-'));
* }
* },
* {
* text : 'Add a toolbar spacer',
* scope : this,
* handler: function() {
* addedItems.push(toolbar.add('->'));
* }
* },
* '->',
* {
* text : 'Remove last inserted item',
* scope : this,
* handler: function() {
* if (addedItems.length) {
* toolbar.remove(addedItems.pop());
* } else if (toolbar.items.length) {
* toolbar.remove(toolbar.items.last());
* } else {
* alert('No items in the toolbar');
* }
* }
* },
* {
* text : 'Remove all items',
* scope : this,
* handler: function() {
* toolbar.removeAll();
* }
* }
* ]
* });
*
