/**
* Create simple buttons with this component. Customisations include {@link #iconAlign aligned}
* {@link #iconCls icons}, {@link #cfg-menu dropdown menus}, {@link #tooltip tooltips}
* and {@link #scale sizing options}. Specify a {@link #handler handler} to run code when
* a user clicks the button, or use {@link #listeners listeners} for other events such as
* {@link #mouseover mouseover}. Example usage:
*
* @example
* Ext.create('Ext.Button', {
* text: 'Click me',
* renderTo: Ext.getBody(),
* handler: function() {
* alert('You clicked the button!');
* }
* });
*
* The {@link #handler} configuration can also be updated dynamically using the {@link #setHandler}
* method. Example usage:
*
* @example
* Ext.create('Ext.Button', {
* text : 'Dynamic Handler Button',
* renderTo: Ext.getBody(),
* handler : function() {
* // this button will spit out a different number every time you click it.
* // so firstly we must check if that number is already set:
* if (this.clickCount) {
* // looks like the property is already set, so lets just add 1 to that number and alert the user
* this.clickCount++;
* alert('You have clicked the button "' + this.clickCount + '" times.\n\nTry clicking it again..');
* } else {
* // if the clickCount property is not set, we will set it and alert the user
* this.clickCount = 1;
* alert('You just clicked the button for the first time!\n\nTry pressing it again..');
* }
* }
* });
*
* A button within a container:
*
* @example
* Ext.create('Ext.Container', {
* renderTo: Ext.getBody(),
* items : [
* {
* xtype: 'button',
* text : 'My Button'
* }
* ]
* });
*
* A useful option of Button is the {@link #scale} configuration. This configuration has three different options:
*
* - `'small'`
* - `'medium'`
* - `'large'`
*
* Example usage:
*
* @example
* Ext.create('Ext.Button', {
* renderTo: document.body,
* text : 'Click me',
* scale : 'large'
* });
*
* Buttons can also be toggled. To enable this, you simple set the {@link #enableToggle} property to `true`.
* Example usage:
*
* @example
* Ext.create('Ext.Button', {
* renderTo: Ext.getBody(),
* text: 'Click Me',
* enableToggle: true
* });
*
* You can assign a menu to a button by using the {@link #cfg-menu} configuration. This standard configuration
* can either be a reference to a {@link Ext.menu.Menu menu} object, a {@link Ext.menu.Menu menu} id or a
* {@link Ext.menu.Menu menu} config blob. When assigning a menu to a button, an arrow is automatically
* added to the button. You can change the alignment of the arrow using the {@link #arrowAlign} configuration
* on button. Example usage:
*
* @example
* Ext.create('Ext.Button', {
* text : 'Menu button',
* renderTo : Ext.getBody(),
* arrowAlign: 'bottom',
* menu : [
* {text: 'Item 1'},
* {text: 'Item 2'},
* {text: 'Item 3'},
* {text: 'Item 4'}
* ]
* });
*
* Using listeners, you can easily listen to events fired by any component, using the {@link #listeners}
* configuration or using the {@link #addListener} method. Button has a variety of different listeners:
*
* - `click`
* - `toggle`
* - `mouseover`
* - `mouseout`
* - `mouseshow`
* - `menuhide`
* - `menutriggerover`
* - `menutriggerout`
*
* Example usage:
*
* @example
* Ext.create('Ext.Button', {
* text : 'Button',
* renderTo : Ext.getBody(),
* listeners: {
* click: function() {
* // this == the button, as we are in the local scope
* this.setText('I was clicked!');
* },
* mouseover: function() {
* // set a new config which says we moused over, if not already set
* if (!this.mousedOver) {
* this.mousedOver = true;
* alert('You moused over a button!\n\nI wont do this again.');
* }
* }
* }
* });
