FMX get Month and Year from calendar after changed in Dropdown in TCalendar

Using the TCalendar, it has a option on top of calendar for previous month , next month buttons. Then it has a dropdown for month and a drop down for year. I cant seem to find out how to get this data when it changes.

Month := Calendar1.???
Year := calendar1.???

Also how to know when the previous, next, month dropdown and year dropdown is selected? On change?

To be clear, I can get month and year from selected date. The question is if they change month and year but don't select day. Then date has not changed so I can't use date to get the current month and year that is in view on the calendar

Solution

  • For example, to output the new date to a memo:

    Memo1.Lines.Add(DateToStr(Calendar1.Date));

    To output to the memo day, month and/or year, add System.DateUtils to uses and write code like:

    Memo1.Lines.Add(IntToStr(DayOf( Calendar1.Date)));
Memo1.Lines.Add(IntToStr(MonthOf( Calendar1.Date)));
Memo1.Lines.Add(IntToStr(YearOf( Calendar1.Date)));

    The OnChange event is the one that gets triggered whenever the date of the calendar is changed.
