QProperties

All Q_PROPERTY and Q_INVOKABLE will be removed from Applet, that is no more directly exposed in QML.

Configuration

We should have a single configuration object binded to qml (either created by autogenerated qml, a model or a property hash)

       KConfigGroup config() const;
       KConfigGroup globalConfig() const;
       ConfigLoader *configScheme() const;

Topic: can this be made flexible enough to replace config read/write? Topic: will need a global version (for globalConfig()) Topic: should we use QML for config, if so: how?

       virtual void save(KConfigGroup &group) const;
       virtual void restore(KConfigGroup &group);
       virtual void configChanged(); -> to signal
       virtual void saveState(KConfigGroup &config) const;
       SIGNAL void configNeedsSaving();
       bool hasConfigurationInterface() const;
       void setHasConfigurationInterface(bool hasInterface);
       void setConfigurationRequired(bool needsConfiguring, const QString &reason = QString());
       bool configurationRequired() const;
       virtual void showConfigurationInterface();
