Calendar - Signal callback and getters.

Most of setters explained on previous examples have associated getters. That's the subject of this example. We'll add a callback to display all calendar information every time user interacts with the calendar.

Let's check our callback function:

To get selected day, we need to call elm_calendar_selected_time_get(), but to assure nothing wrong happened, we must check for function return. It'll return EINA_FALSE if fail. Otherwise we can use time set to our structure stime.

Next we'll get information from calendar and place on declared vars:

The only tricky part is that last line gets an array of strings (char arrays), one for each weekday.

Then we can simple print that to stdin:

struct tm is declared on time.h. You can check ctime manpage to read about it.

To register this callback, that will be called every time user selects a day or goes to next or previous month, just add a callback for signal changed.

Our example will look like this:
