Apparently

are you sure that code is being called? are you certain you are looking in the right directory? – Foppery

yeah sure it called , i have break point and log prints that shows that thid code called and the directory is there – Apparently

Did you try to set any variable, and then destroy m_pSettings? – Mamelon

I ran this code on Qt 4.7.2, same result. The QSettings object is non-null, could call beginWriteArray on it without seg fault. – Bess

Answer 1

I believe in order to force QSettings file to appear you would need to set at least one value in it and then call sync() method. See if an example below would work for you:

QSettings* settings = new QSettings(QDir::currentPath() + "/my_config_file.ini", QSettings::IniFormat);
settings->setValue("test", "value");
settings->sync();

hope this helps, regards

...or create the QSettings object on stack and let the dtor do the sync. – Mightily

Answer 2

I dont think that "/"+CONFIG_FILE_NAME return the expected result. May be the cause of your problem.. Anyway operator +() is present in QString class so QDir::currentPath() + "/my_config_file.ini" must work fine.
