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.
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.
