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();

Completely UI-specific, remove or move to scriptengine

Actions

Keep

       virtual QList<QAction*> contextualActions();
       QAction *action(QString name) const
        void addAction(QString name, QAction *action);

Remove

       void setGlobalShortcut(const KShortcut &shortcut);
       KShortcut globalShortcut() const;
       void activate();
       bool hasAuthorization(const QString &constraint) const;


Constructors

       explicit Applet(QObject *parent = 0, const QString &serviceId = QString(), uint appletId = 0);

Merge the following one into above explicit Applet(QObject *parent, const QString &serviceId, uint appletId, const QVariantList &args);

       explicit Applet(const KPluginInfo &info, QObject *parent = 0, uint appletId = 0);
       Applet(QObject *parent, const QVariantList &args);
       virtual void init();

Associated Application

       void setAssociatedApplication(const QString &string);
       void setAssociatedApplicationUrls(const QList<QUrl> &urls);
       QString associatedApplication() const;
       QList<QUrl> associatedApplicationUrls() const;
       bool hasValidAssociatedApplication() const;
       void runAssociatedApplication(); TODO: ensure that setAssociatedApplication handles .desktop files

Other SIGNALS

Remove

       void releaseVisualFocus();
       void appletTransformedByUser();
       void appletTransformedItself();
       void appletDeleted(Plasma::Applet *applet); TODO: fix usage in Containment

Sharing Widgets

Remote widgets will be completetely removed and eventually reimplemented again later from scratch. TODO: a new and improved revisioned remove widgets (or probably just dataengines and services) system

Remove

       void publish(Plasma::AnnouncementMethods methods, const QString &resourceName);
       void unpublish();
       bool isPublished() const;

To script engine

Move the following to the declarative scriptengine:

       void setBackgroundHints(const Plasma::BackgroundHints hint);
       Plasma::BackgroundHints backgroundHints() const;
       bool isBusy() const;
       void setBusy(bool busy);
       virtual void addAssociatedWidget(QWidget *widget);
       virtual void removeAssociatedWidget(QWidget *widget);
       void messageButtonPressed(const Plasma::MessageButton button);
       void showMessage(const QIcon &icon, const QString &message, const Plasma::MessageButtons buttons);
       SIGNAL void backgroundHintsChanged(Plasma::BackgroundHints backgroundHints);
