+ * @class Ext.picker.Date
+ * @extends Ext.Component
+ * <p>A date picker. This class is used by the {@link Ext.form.field.Date} field to allow browsing and
+ * selection of valid dates in a popup next to the field, but may also be used with other components.</p>
+ * <p>Typically you will need to implement a handler function to be notified when the user chooses a color from the
+ * picker; you can register the handler using the {@link #select} event, or by implementing the {@link #handler}
+ * method.</p>
+ * <p>By default the user will be allowed to pick any date; this can be changed by using the {@link #minDate},
+ * {@link #maxDate}, {@link #disabledDays}, {@link #disabledDatesRE}, and/or {@link #disabledDates} configs.</p>
+ * <p>All the string values documented below may be overridden by including an Ext locale file in your page.</p>
+ * <p>Example usage:</p>
+ * <pre><code>new Ext.panel.Panel({
+ title: 'Choose a future date:',
+ width: 200,
+ bodyPadding: 10,
+ renderTo: Ext.getBody(),
+ items: [{
+ xtype: 'datepicker',
+ minDate: new Date(),
+ handler: function(picker, date) {
+ // do something with the selected date
+ }
+ }]
+});</code></pre>
+ * {@img Ext.picker.Date/Ext.picker.Date.png Ext.picker.Date component}
+ *
+ * @constructor
+ * Create a new DatePicker
+ * @param {Object} config The config object
