\qmltype ApplicationInterface
\inqmlmodule QtApplicationManager.Application
\ingroup app-singletons
\brief The main interface between apps and the application-manager.
This item is available for QML applications using the root context property
\c ApplicationInterface. For other native applications, the same interface
- minus the notification functionality - is available on a private peer-to-peer
D-Bus interface.
For every application that is started in multi-process mode, the application-manager creates
a private P2P D-Bus connection and communicates the connection address to the application's
process via the environment variable \c AM_DBUS_PEER_ADDRESS.
Using this connection, you will have access to different interfaces (note that due to
this not being a bus, the service name is always an empty string):
\table
\header
\li Path \br Name
\li Description
\row
\li \b /ApplicationInterface \br \e io.qt.ApplicationManager.ApplicationInterface
\li Exactly this interface in D-Bus form. The definition is in the source distribution at
\c{src/dbus/io.qt.applicationmanager.applicationinterface.xml}
\row
\li \b /RuntimeInterface \br \e io.qt.ApplicationManager.RuntimeInterface
\li The direct interface between the application-manager and the launcher process, used to
implement custom launchers: the definition is in the source distribution at
\c{src/dbus/io.qt.applicationmanager.runtimeinterface.xml}
\row
\li \b /ExtensionInterfaces/<ext_name> \br \e <ext.name>
\li Any IPC interface registered via the ApplicationIPCManager (and matching the corresponding
filter), will be exported on this P2P connection. The path name is constructed from the
interface name by replacing every character that is not alpha-numeric with an underscore
(\c{_}).
\endtable
If you are re-implementing the client side, note that the remote interfaces are not
available immediately after connecting: they are registered on the server side only after the
client connects. This is a limitation of the D-Bus design - the default implementation attempts
to connect for 100ms before throwing an error.
*/
/*!
\qmlproperty string ApplicationInterface::applicationId
\readonly
The application id of your application.
*/
/*!
\qmlproperty var ApplicationInterface::name
\readonly
An object containing language (\c string) to application name (\c string) mapppings. See
\l{application-name-map}{name} in the manifest (info.yaml) definition.
*/
/*!
\qmlproperty url ApplicationInterface::icon
\readonly
The URL of the application's icon as given in the manifest. This can be used as the source
property of an Image.
*/
/*!
\qmlproperty string ApplicationInterface::version
\readonly
The version of the application as specified in the manifest.
*/
/*!
\qmlproperty var ApplicationInterface::systemProperties
\readonly
Returns the project specific \l{system properties} that were set via the config file.
*/
/*!
\qmlproperty var ApplicationInterface::applicationProperties
\readonly
Returns an object with properties that have been listed under the \c applicationProperties field in the
\l{Manifest Definition}{manifest} file (info.yaml) of the application.
*/
/*!
\qmlmethod Notification ApplicationInterface::createNotification()
Calling this function lets you create a \l Notification object dynamically at runtime.
*/
/*!
\qmlmethod ApplicationInterface::acknowledgeQuit()
This method should be called in response to the \l quit() signal, once the application
is ready to be terminated (e.g. persistent data has been written).
\note This method should be called instead of \c Qt.quit() to obtain the same
behavior in single- and multi-process mode (it does nothing in single process mode).
\sa quit()
*/
/*!
\qmlsignal ApplicationInterface::quit()
The application-manager will send out this signal to an application to request a
controlled shutdown. The application is given a certain amount of time defined in
the configuration (\c quitTime). If the time elapses before acknowledgeQuit() is
called, the application will simply be killed.
\sa acknowledgeQuit()
*/
/*!
\qmlsignal ApplicationInterface::memoryLowWarning()
This signal will be sent out whenever a system dependent free-memory threshold has
been crossed. Your application is expected to free up as many resources as
possible in this case: this will most likely involve clearing internal caches.
\sa memoryCriticalWarning()
*/
/*!
\qmlsignal ApplicationInterface::memoryCriticalWarning()
This signal will be sent out whenever a system dependent free-memory threshold has
been crossed. It is usually sent after a \c memoryLowWarninig and should
be perceived as a last notice to urgently free as many resources as possible to
keep the system stable.
\sa memoryLowWarning()
*/
/*!
\qmlsignal ApplicationInterface::openDocument(string documentUrl, string mimeType)
Whenever an already running application is started again with an argument, the
already running instance will just receive this signal, instead of starting a
separate application instance.
The \a documentUrl parameter received by this function can either be the
\c documentUrl argument of ApplicationManager::startApplication, the \c documentUrl
field of the \l{Manifest definition}{info.yaml} manifest when calling
ApplicationManager::startApplication without a \c documentUrl argument or
the \c target argument of Qt::openUrlExternally, when your application matches
a MIME-type request. In the latter case \a mimeType contains the MIME-type detected
by the ApplicationManager.
