passing QDateTime into QML

mzimmers

Hi all -

I'm trying to pass a QDateTime object into QML, and I seem to be losing the time zone in the process.

    QDateTime m_dateTimeForTimezone { QDateTime::currentDateTimeUtc().toTimeZone(m_timeZone) };
    Q_PROPERTY(QDateTime dateTimeForTimezone READ dateTimeForTimezone WRITE setDateTimeForTimezone NOTIFY dateTimeForTimezoneChanged FINAL)

In my QML:

onClicked: {
    dateTime = clock.dateTimeForTimezone
    console.log("PrefsDateTime.qml: dateTime is " + dateTime) // shows the wrong time.

Evidently, this isn't a new issue: this description seems to be the same thing.

My question: are the proposed solutions in the SO thread really the best way to solve this, or is there a cleaner way to do it?

Thanks...

Not really a solution (more of a band-aid), but...I added properties to my clock for the parts of the date/time I needed:

int m_minutes;
Q_PROPERTY(int minutes READ minutes WRITE setMinutes NOTIFY minutesChanged FINAL)

int m_hours;
Q_PROPERTY(int hours READ hours WRITE setHours NOTIFY hoursChanged FINAL)

and referenced them individually:

property int minutes: clock.minutes
property int hours: clock.hours

Not a great fix, but it got me past the problem.

Nice question I used a string as datetime to avoid the conversion, because I never understand offset on time.
