Question about manipulating single facets of QLocale

dewi 0

Hi all,
the following code is working:

struct comma_separator : std::numpunct<char> {
    virtual char do_decimal_point() const override { return '#'; }
};

int main(int argc, char *argv[])
{
    const double number = 1000.25;

        std::cout << number;
        std::cout.imbue(std::locale(std::cout.getloc(), new comma_separator));
        std::cout << "\"different\" locale: " << number << '\n';
}

How can I get this work with QTextStream ?

Please no answers containing references to the QLocale::toXXX methods.
I just want to change the behaviour of a QTextStream.

Thanks and have fun
Norbert

QTextStream uses QLocale internally to determine the decimal separator so I can't see any way you can do what you are asking. sorry

@VRonin Can it bee that I have been so unclear ?
If I ask for a way to get the code (which mainpulates the std::locale object of cout (which is a stream by the way )) working with QTextStream, it should be evident, that I have to maipulate the QLocale Object which is used by QTextStream. So the answer is: because I want to manipulate the Qlocale used by QTextStream.

Any answer which will help me will be appriciated.

Hi,

Please watch the tone you use when answering. Being aggressive with people taking time to help you is not a good idea.

As it is, QLocale doesn't provide the equivalent of std::locale's facets thus @VRonin is right, you can't do what you want without going down modifying Qt's internals.
