"""
Does a two-stage check if user gives a new date as input.
First, QRegExpValidator checks if the input matches the regular
expression '\d{1,2}\.', i.e. a one- or two-digit number followed by a
dot. If this is accepted, a QDate with the new day is created. If this
is valid (depends on the month, internally handled by QDate), the new
date is assigned to the item.
If any of those validations fails, the user is prompted with a warning
and the date is reset.
