unfortunately you cant use QSettings class this way. It have no public
slots to be used from QML side. You need to write some QmlSettings class
wrapper for QSettings:
class QmlSettings: publicQObject
...
public slots:
QVariant value(const QString &key);
void setValue(const QString &key, const QVariant &value);
...
private:
QSettings *_settings;
...
in class constructor:
_settings = new QSettings("Tanghus", "net.tanghus.currencyconverter.sailfish");
and
QVariant QmlSettings::value(const QString &key){
return _settings->value(key);
}
void QmlSettings::setValue(const QString &key, const QVariant &value){
_settings->setValue(key, value);
}
and then you can use QmlSettings class in QML

Forgive me for non-SailfishOS questions, but I must be doing something wrong,
even if it's easy ;)
My main is now:
int main(int argc, char *argv[]) {
QGuiApplication *app = SailfishApp::application(argc, argv);
QQuickView *view = SailfishApp::createView();
QSettings *settings = new QSettings("Tanghus",
"net.tanghus.currencyconverter.sailfish");
view->rootContext()->setContextProperty("settings", settings);
view-
setSource(SailfishApp::pathTo("qml/net.tanghus.currencyconverter.sailfish.qml"));
view->showFullScreen();
return app->exec();
}
And in ApplicationWindow I can see it's instantiated:
Component.onCompleted: {
console.log('Ready', settings);
}
Prints: Ready QSettings(0x70b633a0)
But if I use it like:
refreshInterval = settings.value('refreshInterval', 3600).toInt();
I get:
file:///opt/sdk/net.tanghus.currencyconverter.sailfish/usr/share/net.tanghus.currencyconverter.sailfish/qml/net.tanghus.currencyconverter.sailfish.qml:64:
TypeError: Object [object Object] has no method 'value'
I'm sure this is very trivial - but atm I'm stuck :P

use QSettings as Jonni said and register own component to use in qml, if
need, or export single class instance via setContextProperty
The latter sounds like the easiest approach.
