tkcalendar 1.3.1

Calendar and DateEntry widgets for Tkinter

tkcalendar is a python module that provides the Calendar and DateEntry widgets for Tkinter. The DateEntry widget is similar to a Combobox, but the drop-down is not a list but a Calendar to select a date. Events can be displayed in the Calendar with custom colors and a tooltip displays the event list for a given day. tkcalendar is compatible with both Python 2 and Python 3. It supports many locale settings (e.g. ‘fr_FR’, ‘en_US’, ..) and the colors are customizable.

Widget methods

• Standard methods:

  • methods common to all tkinter widgets (more details here)

  • methods common to all ttk widgets (more details here)

• Widget-Specific methods:

  calevent_cget(ev_id, option) :

  Return value of given option for the event ev_id.

  calevent_configure(ev_id, **kw) :

  Return value of given option for the event ev_id.

  calevent_create(date, text, tags=[]) :

  Add new event in calendar and return event id.

  Options:

  date: datetime.date or datetime.datetime instance.

  text: text to put in the tooltip associated to date.

  tags: list of tags to apply to the event. The last tag determines the way the event is displayed. If there are several events on the same day, the lowest one (on the tooltip list) which has tags determines the colors of the day.

  calevent_lower(ev_id, below=None) :

  Lower event ev_id in tooltip event list.

  below: put event below given one, if below is None, put it at the bottom of tooltip event list.

  The day’s colors are determined by the last tag of the lowest event which has tags.

  calevent_raise(ev_id, above=None) :

  Raise event ev_id in tooltip event list.

  above: put ev_id above given one, if above is None, put it on top of tooltip event list.

  The day’s colors are determined by the last tag of the lowest event which has tags.

  calevent_remove(*ev_ids, **kw) :

  Remove events from calendar.

  Arguments: event ids to remove or ‘all’ to remove them all.

  Keyword arguments: tag, date. They are taken into account only if no id is given. Remove all events with given tag on given date. If only date is given, remove all events on date and if only tag is given, remove all events with tag.

  get_date() :

  If selectmode is ‘day’, return the string corresponding to the selected date in the Calendar locale, otherwise return "".

  get_calevents(date=None, tag=None) :

  Return event ids of events with given tag and on given date.

  If only date is given, return event ids of all events on date.

  If only tag is given, return event ids of all events with tag.

  If both options are None, return all event ids.

  selection_get() :

  If selectmode is ‘day’, return the selected date as a datetime.date instance, otherwise return None.

  selection_set(self, date) :

  If selectmode is ‘day’, set the selection to date where date can be either a datetime.date

  instance or a string corresponding to the date format "%x" in the Calendar locale. Does nothing if selectmode is "none".

  tag_cget(tag, option) :

  Return the value of the tag’s option.

  tag_config(self, tag, **kw) :

  Configure tag.

  Keyword options: foreground, background (of the day in the calendar)

  tag_delete(tag) :

  Delete given tag and remove it from all events.

  tag_names() :

  Return tuple of existing tags.

DateEntry widget

Date selection entry with drop-down calendar.

Syntax

DateEntry(master=None, **kw)

Widget keyword options

• Keyword options of Calendar to configure the drop-down calendar

• Keyword options of ttk.Entry

  By default, ‘validate’ is set to ‘focusout’ and ‘validatecommand’ is configured so that each time the widget looses focus, if the content is not a valid date (in locale format ‘%x’), it is reset to the previous valid date.

  The widget style is set to ‘DateEntry’. A custom style inheritting from ‘DateEntry’ can be created by naming it ‘<style name>.DateEntry’

• Virtual Events

  A <<DateEntrySelected>> event is generated each time the user selects a date.

Widget methods

• Standard methods:

  • methods common to all tkinter widgets (more details here)

  • methods common to all ttk widgets (more details here)

  • methods of the Entry widget (more details here)

• Widget-Specific methods:

  drop_down() :

  Display or withdraw the drop-down calendar depending on its current state.

  get_date() :

  Return the selected date as a datetime.date instance.

  set_date(self, date) :

  Set the value of the DateEntry to date where date can be either a datetime.date instance or a string corresponding to the date format “%x” in the Calendar locale.
