QDateTime programmatically set invalid

[SPlatten]

I have a QDateTime member in a class, when the user changes state I would like to make this member invalid. I know I can achieve the same by other means, however if there is a way to change a member that is valid to invalid I would like to know.

Hi

Try to assign a default constructed one.

QDateTime test = QDateTime();

In python I did a.setDate(None) (where a was a QDateTime object) and a.isValid() returned False after it.
Probably NULL in C may work either.

@StarterKit , its not a pointer so NULL or nullptr will not work. Setting to QDateTime() does work.
