On this example marks management will be explained. Functions elm_calendar_mark_add(), elm_calendar_mark_del() and elm_calendar_marks_clear() will be covered.
To add a mark, will be required to choose three things:
- mark style
- mark date, or start date if it will be repeated
- mark periodicity
Style defines the kind of mark will be displayed over marked day, on calendar. Default theme supports holiday and checked. If more is required, is possible to set a new theme to calendar widget using elm_object_style_set(), and use the signal that will be used by such marks.
Date is a struct tm
, as defined by time.h
. More can be read on ctime
manpage. If a date relative from current is required, this struct can be set as:
current_time = time(NULL); localtime_r(¤t_time, &selected_time);
Or if it's an absolute date, you can just declare the struct like:
struct tm sunday; struct tm christmas; /* * At least on Windows, tm has 9 fields. * As a workaround, set sunday to 0 and set * th needed fields to correct value */ memset(&sunday, 0, sizeof(struct tm)); sunday.tm_hour = 12; sunday.tm_mday = 7; sunday.tm_isdst = -1; memset(&christmas, 0, sizeof(struct tm)); christmas.tm_mday = 25; christmas.tm_mon = 11;
Periodicity is how frequently the mark will be displayed over the calendar. Can be a unique mark (that don't repeat), or it can repeat daily, weekly, monthly or annually. It's enumerated by Elm_Calendar_Mark_Repeat_Type
.
So let's add some marks to our calendar. We will add christmas holiday, set Sundays as holidays, and check current day and day after that.
struct tm sunday; struct tm christmas; /* * At least on Windows, tm has 9 fields. * As a workaround, set sunday to 0 and set * th needed fields to correct value */ memset(&sunday, 0, sizeof(struct tm)); sunday.tm_hour = 12; sunday.tm_mday = 7; sunday.tm_isdst = -1; memset(&christmas, 0, sizeof(struct tm)); christmas.tm_mday = 25; christmas.tm_mon = 11; current_time = time(NULL); localtime_r(¤t_time, &selected_time); mark = elm_calendar_mark_add(cal, "checked", &selected_time, ELM_CALENDAR_UNIQUE); /* check tomorrow */ current_time = time(NULL) + 1 * SECS_DAY; localtime_r(¤t_time, &selected_time); elm_calendar_mark_add(cal, "checked", &selected_time, ELM_CALENDAR_UNIQUE); /* mark christmas as holiday */ elm_calendar_mark_add(cal, "holiday", &christmas, ELM_CALENDAR_ANNUALLY); /* mark Sundays as holidays */ elm_calendar_mark_add(cal, "holiday", &sunday, ELM_CALENDAR_WEEKLY);
We kept the return of first mark add, because we don't really won't it to be checked, so let's remove it:
elm_calendar_mark_del(mark);
After all marks are added and removed, is required to draw them:
elm_calendar_marks_draw(cal);
Finally, to clear all marks, let's set a callback for our button:
bt = elm_button_add(win); evas_object_size_hint_weight_set(bt, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND); evas_object_size_hint_align_set(bt, EVAS_HINT_FILL, EVAS_HINT_FILL); elm_object_text_set(bt, "Clear marks"); evas_object_smart_callback_add(bt, "clicked", _btn_clear_cb, cal); elm_box_pack_end(bx, bt); evas_object_show(bt);
This callback will receive our calendar object, and should clear it:
static void _btn_clear_cb(void *data, Evas_Object *btn EINA_UNUSED, void *ev EINA_UNUSED) { Evas_Object *cal = data; elm_calendar_marks_clear(cal); elm_calendar_marks_draw(cal); }
- Note:
- Remember to draw marks after clear the calendar.
