Hello everyone, In the last week, I implemented filter comments by author and date functionality. I used `SvtCalendarBox` for the date picker, which is basically `GtkCalendar`. There is one problem though, I don't know of any way to de-select or reset the date selected. So I decided to make a "Reset" button for it. I tried to set the date in the date picker to `Date(Date::EMPTY)` and added some handler to treat this date as if no date is selected. But it didn't work. Should I use something like `gtk_calendar_unmark_day` or `gtk_calendar_clear_marks`?
Thanks, Mohit
