[SailfishDevel] How to handle app settings?

[Bob Jelica]

I use a QML-enabled QSettings wrapper created by Nokia at some point.
Here’s the download link: https://dl.dropboxusercontent.com/u/10015284/qml_settings/settings.cpp and https://dl.dropboxusercontent.com/u/10015284/qml_settings/settings.h
Put those into your project, then register it in your main.cpp (or PROJECTNAME.cpp) like this:

    Settings settings;

    //create the root context and set the context properties
    QQmlContext *rootContext = view->rootContext();

    //register our c++ modules for usage in QML
    rootContext->setContextProperty("settings", &settings);

Now you have a ”settings” object available everywhere in your QML/JS.
Usage:
Save an object: settings.setSetting(”name”, value);
Read a saved object: settings.setting(”name”);

Works like a charm ;)
