This is a calendar widget. It helps applications to flexibly display a calendar 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.

This widget inherits from the Layout one, so that all the functions acting on it also work for calendar objects.

This widget emits the following signals, besides the ones sent from Elm_Layout:

"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)
"language,changed" - the program's language changed (since 1.9)

Supported elm_object common APIs.

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

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

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.

Parameters:

[in]	obj	The object.
[in]	interval	The (first) interval value in seconds

Add a new mark to the calendar.

Add 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.

It won't immediately update the calendar, drawing the marks. For this, elm_calendar_marks_draw(). However, when user selects next or previous month calendar forces marks drawn.

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

Since :: 2.4

Parameters:

[in]	obj	The object.
[in]	mark_type	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.

void elm_calendar_mark_del ( Elm_Calendar_Mark * mark )

Delete mark from the calendar.

Parameters:

mark	The mark to be deleted.

If deleting all calendar marks is required, elm_calendar_marks_clear() should be used instead of getting marks list and deleting each one.

See also:: elm_calendar_mark_add()

void elm_calendar_marks_clear ( Elm_Calendar * obj )

Remove all calendar's marks.

Since :: 2.4

Parameters:

[in] obj The object.
