StartupInterface::~StartupInterface() { }


/*! \class StartupInterface
    \inmodule QtApplicationManager
    \brief An interface that allows to implement custom startup activities.

    This interface provides hooks that are called during the startup of application-manager
    processes. Hence, implementers of the interface can run their custom code at certain points
    during the startup phase.

    A plugin has to implemet the pure virtual functions of the StartupInterface. The interface is
    the same for the System-UI (appman), as well as for QML applications (appman-launcher-qml). The
    plugins that should be loaded have to be specified in the (am-config.yaml) configuration file.
    The following snippet shows how the application-manager can be configured to load and execute
    the \c libappmanplugin.so in both the System-UI and applications and additionally the
    \c libextplugin.so in the System-UI only:

    \badcode
    # System-UI
    plugins:
      startup: [ "path/to/libappmanplugin.so", "path/to/libextplugin.so" ]

    # Applications
    runtimes:
      qml:
        startup: "path/to/libappmanplugin.so"
    \endcode

    The functions are called in the following order:
    \list
    \li \l{StartupInterface::initialize}{initialize}
    \li afterRuntimeRegistration (optional)
    \li beforeQmlEngineLoad
    \li afterQmlEngineLoad
    \li beforeWindowShow
    \li afterWindowShow (optional)
    \endlist
*/

/*! \fn void StartupInterface::initialize(const QVariantMap &systemProperties)

    This method is called right after the \l{system properties}{\a systemProperties} have been parsed.
*/

/*! \fn void StartupInterface::afterRuntimeRegistration()

    This method is called, right after the runtime has been registered.
    \note It will only be called in the System-UI process.
*/

/*! \fn void StartupInterface::beforeQmlEngineLoad(QQmlEngine *engine)

    This method is called, before the QML \a engine is loaded.
*/

/*! \fn void StartupInterface::afterQmlEngineLoad(QQmlEngine *engine)

    This method is called, after the QML \a engine has been loaded.
*/

/*! \fn void StartupInterface::beforeWindowShow(QWindow *window)

    This method is called, after the main window has been instantiated, but before it is shown. The
    \a window parameter holds a pointer to the main window.
    \note The \a window is only valid, if the root object of your QML tree is a visible item (e.g.
    a \l{Window} or \l{Item} derived class). It will be a \c nullptr, if it is a QtObject for
    instance.
*/

/*! \fn void StartupInterface::afterWindowShow(QWindow *window)

    This method is called, right after the main window is shown. The \a window parameter holds a
    pointer to the just shown main window.
    \note This function will only be called, if the root object of your QML tree is a visible item
    (e.g. a \l{Window} or \l{Item} derived class). It will not be called, if it is a QtObject for
    instance.
