invalidate QDateTime

[Markus_AC]

I want to invalidate QDateTime or at least member date of QDateTime. When creating a new QDateTime it's invalid by default. But how can I get to this state after having had a vaild date?

Umm, assign a new invalid value to it:

QDateTime test = QDateTime::currentDateTime();
qDebug() << test.isValid();  // true
test = QDateTime();
qDebug() << test.isValid();  // false;

QDateTime test = QDateTime::currentDateTime();
qDebug() << test.isValid();  // true
test = QDateTime();
qDebug() << test.isValid();  // false;

To copy to clipboard, switch view to plain text mode
