QDateTimeEdit DateTimeChanged

as the variable that suppose to save the date

Which variable is that and where do you set it?
Is it myDateTime? If so: where do you set it?
You set pMyDateTime, but then you check myDateTime, why?

[Phamy1289]

@jsulm Sorry that's a typo. let me fix it. I was hoping to store the mpStartDateTime into the variable pMyDateTime whenever mpStartDate gets a change in the date and time. For example, the date changes from the current date to date 2 years ago. From 11/5/2021 to 02/15/2019. I want pMyDateTime to store 02/15/2019. If mpStartDateTime were to change dates and/or time again, then pMyDateTime would store the new date and/or time.

pMyDateTime.dateTimeChanged(mpStartDateTime->dateTime());

Why do you call a signal here?!
Why not simply

QDateTimeEdit *pMyDateTime = new QDateTimeEdit(mpStartDateTime->dateTime());

?

So, now that i'm getting the right dateTime from mpStartDateTime, how do I keep track of the new dateTime in mpStartDateTime if the user selects a different date from the calendar?

Hi,

That's what the signal is for.

[Phamy1289]

The date isn't changing when I change the date. Am I using the signal/slot incorrectly? mpStartDateTime is and QDateTimeEdit and is set to the current date and time when the application launches, I don't know if that matters or not.

connect(mpStartDateTime, SIGNAL(dateTimeChanged(QDateTime)), this, SLOT(updateDateTime(const QDateTime)));

            for(auto it = root.begin(); it != root.end(); ++it)
            {
                if(it.key() == "startDate")
                {
                    if(it.value().toString() >= mpStartDateTime->text())
                    {
                        std::cout << mpStartDateTime->text().toStdString() << " ";
                    }
                    else
                    {
                        std::cout << mpStartDateTime->text().toStdString() << " ";
                    }
                }

void ScheduleAdvice::updateDateTime(const QDateTime dateTime)
{
    mpStartDateTime->setDateTime(dateTime);
}

@Phamy1289
Start by putting qDebug() << dateTime; into updateDateTime. Is it called at all, is the value correct?

I don't understand what you're trying to do.
You connect a signal from mpStartDateTime and in the slot connected to that signal you change mpStartDateTime - what's the point?

[Phamy1289]

@JonB It does comeback with the correct value.

@jsulm I have a calendar popup and table full of data from a QJSON where start date is one of them attributes. I want to be able to filter that data with the date selected from the popup which the user can choose the date. I would like this to update live as the user changes the start date.

In that case you can be sure that mpStartDateTime->setDateTime(dateTime); sets that value into *mpStartDateTime.

@JonB You're right. I did a test and it does update mpStartDateTime. Thank you!
