\brief The ApplicationManagerWindow item
This QML item should 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.
If you are not using ApplicationManagerWindow as the QML root item, your application will only
work in multi-process (Wayland) mode.
The QML import for this item is
\c{import QtApplicationManager 1.0}
After importing, you can instantiate the QML item like so:
\qml
import QtQuick 2.0
import QtApplicationManager 1.0
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} directory in it
\li Add a file named \c qmldir there, consisting of the single line \c{ApplicationManagerWindow 1.0 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 qmlscene with \c{qmlscene -I <path to base dir>}
