Calendar¶

Widget description¶

This is a calendar widget.

It helps applications to flexibly display a calender with day of the week, date, year and month. Applications are able to set specific dates to be reported back, when selected, in the smart callbacks of the calendar widget. The API of this widget lets the applications perform other functions, like:

placing marks on specific dates
setting the bounds for the calendar (minimum and maximum years)
setting the day names of the week (e.g. “Thu” or “Thursday”)
setting the year and month format.

Emitted signals¶

changed - emitted when the date in the calendar is changed.
display,changed - emitted when the current month displayed in the calendar is changed.
focused - When the calendar has received focus. (since 1.8)
unfocused - When the calendar has lost focus. (since 1.8)

Inheritance diagram¶

class efl.elementary.Calendar(Object parent, *args, **kwargs)¶

Bases: efl.elementary.__init__.LayoutClass

Parameters:	parent (`efl.evas.Object`) – The parent object **kwargs – All the remaining keyword arguments are interpreted as properties of the instance

callback_changed_add(func, *args, **kwargs)¶: Emitted when the date in the calendar is changed.

callback_changed_del(func)¶

callback_display_changed_add(func, *args, **kwargs)¶: Emitted when the current month displayed in the calendar is changed.

callback_focused_add(func, *args, **kwargs)¶: When the calendar has received focus.

New in version 1.8.

callback_focused_del(func)¶

callback_unfocused_add(func, *args, **kwargs)¶: When the calendar has lost focus.

New in version 1.8.

callback_unfocused_del(func)¶

displayed_time¶

Get the current time displayed in the widget

Type:	datetime.date

New in version 1.8.

first_day_of_week¶

The first day of week to use on the calendar widget.

Type:	int

interval¶

Set the interval on time updates for an user mouse button hold on calendar widgets’ month selection.

This interval value is decreased while the user holds the mouse pointer either selecting next or previous month.

This helps the user to get to a given month distant from the current one easier/faster, as it will start to change quicker and quicker on mouse button holds.

The calculation for the next change interval value, starting from the one set with this call, is the previous interval divided by 1.05, so it decreases a little bit.

The default starting interval value for automatic changes is 0.85 seconds.

Type:	float

mark_add(mark_type, mark_time, repeat)¶

A constructor for a CalendarMark.

Parameters:	mark_type (string) – A string used to define the type of mark. It will be emitted to the theme, that should display a related modification on these days representation. mark_time (datetime.date) – A date object to represent the date of inclusion of the mark. For marks that repeats it will just be displayed after the inclusion date in the calendar. repeat (Calendar mark repeat types) – Repeat the event following this periodicity. Can be a unique mark (that don’t repeat), daily, weekly, monthly or annually.
Returns:	The created mark or `None` upon failure.
Return type:	`CalendarMark`

marks¶

Calendar marks.

Type:	list of `CalendarMark`

marks_draw()¶

Draw calendar marks.

Should be used after adding, removing or clearing marks. It will go through the entire marks list updating the calendar. If lots of marks will be added, add all the marks and then call this function.

When the month is changed, i.e. user selects next or previous month, marks will be drawn.

Seealso:	`CalendarMark`

min_max_year¶

The minimum and maximum values for the year

Maximum must be greater than minimum, except if you don’t want to set maximum year. Default values are 1902 and -1.

If the maximum year is a negative value, it will be limited depending on the platform architecture (year 2037 for 32 bits)

Type:	(int min, int max)

select_mode¶

The day selection mode used.

Type:	Calendar selection modes

selectable¶

How selected_time manages a date

Type:	Selectable

New in version 1.8.

selected_time¶

Selected date on the calendar.

Setting this changes the displayed month if needed. Selected date changes when the user goes to next/previous month or select a day pressing over it on calendar.

Type:	datetime.date

Changed in version 1.8: Returns None when the selected date cannot be fetched.

The usage should be like this:

weekdays =
(
  "Sunday", "Monday", "Tuesday", "Wednesday",

)
calendar.weekdays_names = weekdays

Type:	tuple of strings

Warning

class efl.elementary.CalendarMark(Object cal, mark_type, mark_time, Elm_Calendar_Mark_Repeat_Type repeat)¶

Bases: object

A mark that will be drawn in the calendar respecting the insertion time and periodicity. It will emit the type as signal to the widget theme. Default theme supports “holiday” and “checked”, but it can be extended.

Instantiating it won’t immediately update the calendar, drawing the marks. For this, call Calendar.marks_draw(). However, when user selects next or previous month calendar forces marks drawn.

Marks created with this method can be deleted with delete().

Example:

from datetime import date, timedelta

cal = Calendar(win)

selected_time = date.today() + timedelta(5)
cal.mark_add("holiday", selected_time, ELM_CALENDAR_ANNUALLY)

selected_time = date.today() + timedelta(1)
cal.mark_add("checked", selected_time, ELM_CALENDAR_UNIQUE)

cal.marks_draw()

Parameters:	parent (`efl.evas.Object`) – The parent object mark_type (string) – A string used to define the type of mark. It will be emitted to the theme, that should display a related modification on these days representation. mark_time (datetime.date) – A date object to represent the date of inclusion of the mark. For marks that repeats it will just be displayed after the inclusion date in the calendar. repeat (Calendar mark repeat types) – Repeat the event following this periodicity. Can be a unique mark (that don’t repeat), daily, weekly, monthly or annually.
Returns:	The created mark or `None` upon failure.
Return type:	`CalendarMark`

delete()¶

Delete a mark from the calendar.

If deleting all calendar marks is required, del Calendar.marks should be used instead of getting marks list and deleting each one.
