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 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)

double elm_calendar_interval_get ( const Elm_Calendar * obj )

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.

Returns:: The (first) interval value in seconds

Since :: 2.4

Examples:: calendar_example_05.c.

void elm_calendar_interval_set	(	Elm_Calendar *	obj,

		const char *	mark_type,
		Efl_Time *	mark_time,
		Elm_Calendar_Mark_Repeat_Type	repeat
	)

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().

[in]	repeat	Repeat the event following this periodicity. Can be a unique mark (that don't repeat), daily, weekly, monthly or annually.

Returns:: The newly added calendar mark
