/**
+ * @docauthor Robert Dougan <rob@sencha.com>
+ *
+ * Single checkbox field. Can be used as a direct replacement for traditional checkbox fields. Also serves as a
+ * parent class for {@link Ext.form.field.Radio radio buttons}.
+ *
+ * # Labeling
+ *
+ * In addition to the {@link Ext.form.Labelable standard field labeling options}, checkboxes
+ * may be given an optional {@link #boxLabel} which will be displayed immediately after checkbox. Also see
+ * {@link Ext.form.CheckboxGroup} for a convenient method of grouping related checkboxes.
+ *
+ * # Values
+ *
+ * The main value of a checkbox is a boolean, indicating whether or not the checkbox is checked.
+ * The following values will check the checkbox:
+ *
+ * - `true`
+ * - `'true'`
+ * - `'1'`
+ * - `'on'`
+ *
+ * Any other value will uncheck the checkbox.
+ *
+ * In addition to the main boolean value, you may also specify a separate {@link #inputValue}. This will be
+ * sent as the parameter value when the form is {@link Ext.form.Basic#submit submitted}. You will want to set
+ * this value if you have multiple checkboxes with the same {@link #name}. If not specified, the value `on`
+ * will be used.
+ *
+ * # Example usage
+ *
+ * @example
+ * Ext.create('Ext.form.Panel', {
+ * bodyPadding: 10,
+ * width: 300,
+ * title: 'Pizza Order',
+ * items: [
+ * {
+ * xtype: 'fieldcontainer',
+ * fieldLabel: 'Toppings',
+ * defaultType: 'checkboxfield',
+ * items: [
+ * {
+ * boxLabel : 'Anchovies',
+ * name : 'topping',
+ * inputValue: '1',
+ * id : 'checkbox1'
+ * }, {
+ * boxLabel : 'Artichoke Hearts',
+ * name : 'topping',
+ * inputValue: '2',
+ * checked : true,
+ * id : 'checkbox2'
+ * }, {
+ * boxLabel : 'Bacon',
+ * name : 'topping',
+ * inputValue: '3',
+ * id : 'checkbox3'
+ * }
+ * ]
+ * }
+ * ],
+ * bbar: [
+ * {
+ * text: 'Select Bacon',
+ * handler: function() {
+ * Ext.getCmp('checkbox3').setValue(true);
+ * }
+ * },
+ * '-',
+ * {
+ * text: 'Select All',
+ * handler: function() {
+ * Ext.getCmp('checkbox1').setValue(true);
+ * Ext.getCmp('checkbox2').setValue(true);
+ * Ext.getCmp('checkbox3').setValue(true);
+ * }
+ * },
+ * {
+ * text: 'Deselect All',
+ * handler: function() {
+ * Ext.getCmp('checkbox1').setValue(false);
+ * Ext.getCmp('checkbox2').setValue(false);
+ * Ext.getCmp('checkbox3').setValue(false);
+ * }
+ * }
+ * ],
+ * renderTo: Ext.getBody()
