[Solved] QDate::fromString() dateformat restrictions.

Woody

I want to parse an incomming text to a date format.

But since I live in Belgium, people often use format dd/mm/yyyy.

It seems that Qt, can't handle this kind of date.

Are there any restrictings on QDate::fromString()?
If yes, please tell me where I can find them.

Thanks in advance.

Yes it can you need to tell it the format though so something like QDate::fromString("22112012", "dMyyyy"); that should do the trick read here http://doc.qt.digia.com/qt/qdate.html#fromString for further info.

"QDate::fromString()":http://doc.qt.digia.com/qt/qdate.html#fromString-2

@QString str("11/11/2011");
QDate converted_date(QDate::fromString(str, "dd/MM/yyyy"));@

Watch the case MM is months while mm is minutes

I think I phrased my question wrong.

This is what a want to achieve:
@birthdate = (QDate::fromString(23/11/2012, "yyyy-MM-dd").isValid() ? QDate::fromString(23/11/2012, "yyyy-MM-dd") : QDate(1970,01,01));@

Birthdate has to be the format yyyy-MM-dd
So I get an inputdate of dd/MM/yyyy and I want to get yyyy-MM-dd into my database.

Is it possible to be not possible? Do you have to split the date yourself?

Nosf

is the input format constant?

if so just use

@QDate::fromString(variable, "dd/MM/yyyy");@

If you don't there isn't a foolproof way of getting it correctly. If this is an input from the user use a validator to validate their input and check the format is right or do a string replace with regex

@variable = variable.replace(QRegExp("[/, ]"), "-");
QDate::fromString(variable, "dd-MM-yyyy");@

I have it and it worked well
@
QString Tsysfun::SSQLDat(QDateTime v)
{
const sformat="yyyy-MM-dd hh:mm:ss";
return QString("'%1'").arg(QDateTime::fromString(v.toString(),Qt::TextDate).toString(sformat));
}@

Thanks Nosf, it the closest I'm going to get to a solution.

The input format isn't constant.

The user get to choose the format, but I don't know what formats that can be.

But for now it's 'solved'.

Thanks!
