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
libappmanplugin.so in both the System-UI and applications and additionally the
libextplugin.so in the System-UI only:
# System-UI plugins: startup: [ "path/to/libappmanplugin.so", "path/to/libextplugin.so" ] # Applications runtimes: qml: startup: "path/to/libappmanplugin.so"
The functions are called in the following order:
Member Function Documentation
[pure virtual] void StartupInterface::afterQmlEngineLoad(QQmlEngine *engine)
This method is called, after the QML engine has been loaded.
This method is called, right after the runtime has been registered.
Note: It will only be called in the System-UI process.
This method is called, right after the main window is shown. The window parameter holds a pointer to the just shown main window.
[pure virtual] void StartupInterface::beforeQmlEngineLoad(QQmlEngine *engine)
This method is called, before the QML engine is loaded.
QtApplicationManager* QML namespaces are locked for new registrations via qmlProtectModule() after this call.
This method is called, after the main window has been instantiated, but before it is shown. The window parameter holds a pointer to the main window.
[pure virtual] void StartupInterface::initialize(const QVariantMap &systemProperties)
This method is called right after the systemProperties have been parsed.
