\ingroup app
\brief The window root item required in a multi-process environment.
This QML item can be used as the root item in your QML application. In doing so, you enable
your application to be usable in both single-process (EGL fullscreen, desktop) and
multi-process (Wayland) mode. It inherits from \l Window in multi-process and from \l Item in
single-process mode. In contrast to a \l Window it is visible by default. Additional details can
be found in the section about \l {The Root Element}{the root element}.
The QML import for this item is
\c{import QtApplicationManager.Application 2.0}
After importing, you can instantiate the QML item like so:
\qml
import QtQuick 2.0
import QtApplicationManager.Application 2.0
ApplicationManagerWindow {
Text {
text: ApplicationInterface.applicationId
}
}
\endqml
In order to make your applications easily runnable outside of the application-manager, even
though you are using a ApplicationManagerWindow as a root item, you can simply provide this
little dummy import to your application.
\list 1
\li Pick a base dir and create a \c{QtApplicationManager.Application} directory in it
\li Add a file named \c qmldir there, consisting of the single line \c{ApplicationManagerWindow 2.0 ApplicationManagerWindow.qml}
\li Add a second file named \c ApplicationManagerWindow.qml, with the following content
\qml
import QtQuick 2.0
Item {
width: 1280 // use your screen width here
height: 600 // use your screen height here
function close() {}
function showFullScreen() {}
function showMaximized() {}
function showNormal() {}
}
\endqml
\endlist
Now you can run your appication within \c qmlscene (or \c qml) with e.g.
\c{qmlscene -I <path to base dir>}

Sets this application window's shared property identified by \a name to the given \a value.
These properties are shared between the System-UI and the client applications: in single-process
mode simply via a QVariantMap; in multi-process mode via Qt's extended surface Wayland extension.
Changes from the client side are signalled via windowPropertyChanged.
See WindowManager for the server side API.
\note When listening to property changes of Wayland clients on the System-UI side, be aware of
the \l{Multi-process Wayland caveats}{asynchronous nature} of the underlying Wayland
protocol.
