Getting QDate from string

[yagabey]

Hello,

I can parse "31 Jan 2009" by the code:

QString day=datelist[1]; //datelist contains 31 and Jan and 2009 here...
QString month=datelist[2];
QString year =datelist[3];
QDate todate= QDate::fromString(day+"/"+month+"/"+year,"dd/MMM/yyyy");

QString day=datelist[1]; //datelist contains 31 and Jan and 2009 here...
QString month=datelist[2];
QString year =datelist[3];
QDate todate= QDate::fromString(day+"/"+month+"/"+year,"dd/MMM/yyyy");

To copy to clipboard, switch view to plain text mode 

But the same code cannot parse a date with february like "01 Feb 2009" . What is the problem with Feb?

try

QDate::fromString(input, "dd MMM yyyy");

QDate::fromString(input, "dd MMM yyyy");

If you produce the output with QDate::toString(), just use the same format both times.
If you use no format for toString(), use none for fromString().

To your problem:
where does your input come from?
In case it is user input: Perhaps you have a loc ale set that happens to have "Jan" for january but something different from "Feb" for february?
(check by printing qDebug() << date.toString() )

Actually I am parsing an email header like:

I grab the "Date:.." part, clean unnecessary things...
I put day to day(in number format), month to month(that is character format), year to year..The actual code is:

QString dayremoved;
QStringList datelist;
dayremoved= dateHeader.section(",",1,1);
datelist = dayremoved.split(" ");
QString day=datelist[1];
QString month=datelist[2];
QString year =datelist[3];
QDate todate= QDate::fromString(day+"/"+month+"/"+year,"dd/MMM/yyyy");

QString dayremoved;
QStringList datelist;
dayremoved= dateHeader.section(",",1,1);
datelist = dayremoved.split(" ");
QString day=datelist[1];
QString month=datelist[2];
QString year =datelist[3];
QDate todate= QDate::fromString(day+"/"+month+"/"+year,"dd/MMM/yyyy");

To copy to clipboard, switch view to plain text mode 

QDate::fromString(input, "dd MMM yyyy");

QDate::fromString(input, "dd MMM yyyy");

To copy to clipboard, switch view to plain text mode 

also didn't work?

[caduel]

note that "dd" expects leading zeros (01, 02, ...) whereas "d" does not (1, 2, ...).

[yagabey]

Yes you've go it It works now...!

[wysota]

Correct me if I'm wrong but this is basically the Qt::TextDate format, isn't it?

[yagabey]

yes it is...

[wysota]

So why not simply use:

QDateTime::fromString(input, Qt::TextDate)

QDateTime::fromString(input, Qt::TextDate)

To copy to clipboard, switch view to plain text mode 

? The only possible problem is the time zone at the end of the string.

I've a similar problem. I need to convert 24-10-1977 (and 24/10/1977) to 1977-10-24

I've tried with:

QString fdate = value.value<QString>();
QDate qdate = QDate::fromString(fdate,"dd-mm-yyyy");

qDebug() << qdate.toString(Qt::ISODate);

the last row output is null.

It doesn't work. Any idea?

[spirit]

what will you get if you do this?

....
qDebug() << qicssmtpmailer;
....

....
qDebug() << qicssmtpmailer;
....

[giandrea77]

solve. The correct line is:

QDate qdate = QDate::fromString(fdate,"d-M-yyyy");
