Problem with QSettings

amy.cpp

Hi guys!
Can you explain me why this code doesn't work?
It looks so easy.

QSettings settings;
settings.setValue("key", 123);

settings.sync();

qInfo() << settings.value("key");

return a.exec();

Thank you

Bonnie

Is that your full code about QSettings?
Then according to the doc:

QSettings::QSettings(QObject *parent = nullptr)

Constructs a QSettings object for accessing settings of the application and organization set previously with a call to QCoreApplication::setOrganizationName(), QCoreApplication::setOrganizationDomain(), and QCoreApplication::setApplicationName().
The scope is QSettings::UserScope and the format is defaultFormat() (QSettings::NativeFormat by default). Use setDefaultFormat() before calling this constructor to change the default format used by this constructor.
The code

QSettings settings("Moose Soft", "Facturo-Pro");

is equivalent to

QCoreApplication::setOrganizationName("Moose Soft");
QCoreApplication::setApplicationName("Facturo-Pro");
QSettings settings;

If QCoreApplication::setOrganizationName() and QCoreApplication::setApplicationName() has not been previously called, the QSettings object will not be able to read or write any settings, and status() will return AccessError.

You could try using a filename when creating QSettings:
QSettings settings("settings.ini", QSettings::IniFormat);
