.. _wx.adv.GenericCalendarCtrl:

==========================================================================================================================================
|phoenix_title|  **wx.adv.GenericCalendarCtrl**
==========================================================================================================================================

The calendar control allows the user to pick a date.          

The user can move the current selection using the keyboard and select the date (generating  ``EVT_CALENDAR``   event) by pressing   ``<Return>``   or double clicking it. 

Generic calendar has advanced possibilities for the customization of its display, described below. If you want to use these possibilities on every platform, use GenericCalendarCtrl instead of :ref:`wx.adv.CalendarCtrl`. 

All global settings (such as colours and fonts used) can, of course, be changed. But also, the display style for each day in the month can be set independently using :ref:`wx.adv.CalendarDateAttr`  class. 

An item without custom attributes is drawn with the default colours and font and without border, but setting custom attributes with :meth:`~wx.adv.GenericCalendarCtrl.SetAttr`  allows modifying its appearance. Just create a custom attribute object and set it for the day you want to be displayed specially (note that the control will take ownership of the pointer, i.e. it will delete it itself). A day may be marked as being a holiday, even if it is not recognized as one by :ref:`wx.DateTime`  using the :meth:`wx.adv.CalendarDateAttr.SetHoliday`   method. 

As the attributes are specified for each day, they may change when the month is changed, so you will often want to update them in  ``EVT_CALENDAR_PAGE_CHANGED``   event handler. 

If neither the  ``CAL_SUNDAY_FIRST``   or   ``CAL_MONDAY_FIRST``   style is given, the first day of the week is determined from operating system's settings, if possible. The native wxGTK calendar chooses the first weekday based on locale, and these styles have no effect on it. 





.. _GenericCalendarCtrl-styles:

|styles| Window Styles
================================

This class supports the following styles: 

  

- ``wx.adv.CAL_SUNDAY_FIRST``: Show Sunday as the first day in the week (not in wxGTK)  
- ``wx.adv.CAL_MONDAY_FIRST``: Show Monday as the first day in the week (not in wxGTK)  
- ``wx.adv.CAL_SHOW_HOLIDAYS``: Highlight holidays in the calendar (only generic)  
- ``wx.adv.CAL_NO_YEAR_CHANGE``: Disable the year changing (deprecated, only generic)  
- ``wx.adv.CAL_NO_MONTH_CHANGE``: Disable the month (and, implicitly, the year) changing  
- ``wx.adv.CAL_SHOW_SURROUNDING_WEEKS``: Show the neighbouring weeks in the previous and next months (only generic, always on for the native controls)  
- ``wx.adv.CAL_SEQUENTIAL_MONTH_SELECTION``: Use alternative, more compact, style for the month and year selection controls. (only generic)  
- ``wx.adv.CAL_SHOW_WEEK_NUMBERS``: Show week numbers on the left side of the calendar. (not in generic)  








.. _GenericCalendarCtrl-events:

|events| Events Emitted by this Class
=====================================

Handlers bound for the following event types will receive a :ref:`wx.adv.CalendarEvent` parameter.


- EVT_CALENDAR: A day was double clicked in the calendar.  
- EVT_CALENDAR_SEL_CHANGED: The selected date changed.  
- EVT_CALENDAR_PAGE_CHANGED: The selected month (and/or year) changed.  
- EVT_CALENDAR_WEEKDAY_CLICKED: User clicked on the week day header (only generic).  
- EVT_CALENDAR_WEEK_CLICKED: User clicked on the week of the year number (only generic).  








Implementations:GTK, MSW ports; a generic implementation is used elsewhere. 

         



.. note:: 

   Changing the selected date will trigger an ``EVT_CALENDAR_DAY``, ``MONTH`` or ``YEAR`` event as well as an ``EVT_CALENDAR_SEL_CHANGED`` event.
