Another Exception with locale: cannot convert ‘const QString’ to ‘const QLocale&’

xavierbaez

I got another problem with Qlocale

Here is the code in the header file
Validating.h:

void setLocale(const QString& locale);

Here is the code in the C++ file
Validating.cpp:

void Validating::setLocale(const QString& locale)
{
    QValidator::setLocale(locale);
}

Here is the error

error: cannot convert ‘const QString’ to ‘const QLocale&’
 |     QValidator::setLocale(locale);
 |                                             ^~~~~~

Thanks in advance

@xavierbaez said in Another Exception with locale: cannot convert ‘const QString’ to ‘const QLocale&’:

{
QValidator::setLocale(locale);
}

what you probably want is:

void Validating::setLocale(const QString& locale)
{
     QValidator::setLocale(QLocale(locale));
}

which will create a QLocale object from your QString and pass it on to QValidator.

@xavierbaez The error message is very clear and if you read documentation (https://doc.qt.io/qt-6/qvalidator.html#setLocale) you will see that setLocale expects a QLocale as parameter, not QString.

I replaced it with this code:
Validating.h

void setLocale(const QLocale &locale);

void Validating::setLocale(const QLocale &locale)
{
    QValidator::setLocale(&locale);
}

I get the following error:

initializing argument 1 of ‘void Validating::setLocale(const QLocale&)’
   15 |     void setLocale(const QLocale &locale);

Why are you trying to pass a pointer here?!

Would you be so kind to write the suggested code?
I tried everythning

15 |     void setLocale(const QLocale& locale);

If you change it

15 |     void setLocale(const QLocale locale);

jsulm

@xavierbaez You did not answer my question: "Why are you trying to pass a pointer here?!"
So, simply replace

QValidator::setLocale(&locale);

with

QValidator::setLocale(locale);

xavierbaez

@jsulm

Okay so the header like this

void setLocale(const QLocale &locale);

And the cpp file like this?

void Validating::setLocale(const QLocale &locale) { QValidator::setLocale(locale); 
}

@J-Hilk Thank you that worked.
I also changed the header to:

void setLocale(const QString& locale);
