/** * For an overview of calendar views see {@link Ext.calendar.view.Base} * * The Month view shows events over an entire month. The view shows a summary of the * events that occur on each day. The month view uses the current date (or the date set * on the {@link #value} config) to determine the month to show. * * The Month view displays (as needed) days from trailing/leading months as required to * fill the space in the view based on the {@link #value} and the * {@link #firstDayOfWeek}. In the following example, the view will start on Sun Dec * 27 and conclude on Sat Feb 6 because we require 6 rows to display the month of * January. * * { * value: new Date(2010, 0, 1) // Fri * firstDayOfWeek: 0 // Sunday * } * * The {@link #visibleWeeks} can be specified as `null` to allow the view to * calculate the appropriate number of rows to show in the view, as this varies * from month to month. This defaults to the largest possible value (6 weeks) so that * the view size is consistent across months. * * ### Date Range Navigation * * In addition to {@link #navigate}, {@link #movePrevious}, and * {@link #moveNext} the Month view let you quickly navigate between months and * years. The {@link #previousMonth} and {@link #nextMonth} methods allow for * programmatic month-to-month navigation while {@link #previousYear} and * {@link #nextYear} navigate the view across years. * * ### Alternative Classes * * If your view requires a header showing the days of the week consider using * {@link Ext.calendar.panel.Weeks} instead. For a multi-week view refer to * {@link Ext.calendar.view.Weeks}. */Ext.define('Ext.calendar.view.Month', { extend: 'Ext.calendar.view.Weeks', xtype: 'calendar-monthview', config: { /** * @cfg {Date} [value=new Date()] * The current month to show.
