Qt 5.5.0
I'm switching one of my gui applications to console. I'm having a problem with QSettings object initiation in console mode.
This is the code in gui, it works fine:
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow();
QSettings *Setts; //settigns
...
}
MainWindow::MainWindow()
{
QFile setfile("./SA/Settings.ini");
if (setfile.exists())
setfile.setPermissions(setfile.permissions() | QFileDevice::ReadUser | QFileDevice::WriteUser);
Setts = new QSettings("./SA/Settings.ini", QSettings::IniFormat);
setfile.setFileName(Setts->value("Localization","./SA/en.loc").toString());
...
}
int main(int argc, char *argv[])
{
QPointer<QApplication> app;
QPointer<MainWindow> main_window;
app = new QApplication(argc, argv);
main_window = new MainWindow();
...
}
and this is code for console
class MainWindow : public QObject
{
Q_OBJECT
public:
MainWindow();
~MainWindow();
QSettings *Setts; //settigns
...
}
MainWindow::MainWindow()
{
QFile setfile("./SA/Settings.ini");
if (setfile.exists())
setfile.setPermissions(setfile.permissions() | QFileDevice::ReadUser | QFileDevice::WriteUser);
Setts = new QSettings("./SA/Settings.ini", QSettings::IniFormat);
setfile.setFileName(Setts->value("Localization",QString("./SA/en.loc")).toString());
...
}
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
MainWindow mw;
...
}
Console code fails over calling Setts->value with the error: ASSERT failure in QVariant: "Trying to construct an unknown type", file kernel\qvariant.cpp, line 980.
While debugging I noticed warnings when I enter class constructor: can't find linker symbol for virtual table for `QSettings' value.
I tried multiple ways, QSettings doesn`t initialize values in its constructor, though the file is present. Calling Setts->contains("Localization") also gives the same error. But if I use Setts->setValue after constructor, it works fine. What can I do to make QSettings initialize in constructor?
