Detailed Description

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 Window in multi-process and from Item in single-process mode. In contrast to a Window it is visible by default. Additional details can be found in the section about the root element.

The QML import for this item is

import QtApplicationManager.Application 2.0

After importing, you can instantiate the QML item like so:

import QtQuick 2.0
import QtApplicationManager.Application 2.0

ApplicationManagerWindow {
    Text {
        text: ApplicationInterface.applicationId
    }
}

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.

  1. Pick a base dir and create a QtApplicationManager.Application directory in it
  2. Add a file named qmldir there, consisting of the single line ApplicationManagerWindow 2.0 ApplicationManagerWindow.qml
  3. Add a second file named ApplicationManagerWindow.qml, with the following content
    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() {}
    }

Now you can run your appication within qmlscene (or qml) with e.g. qmlscene -I <path to base dir>

Signal Documentation

windowPropertyChanged(name, var value)

Reports a change of this application window's property identified by name to the given value.

See also setWindowProperty.


Method Documentation

void setWindowProperty(name, var &value)

Sets this application window's shared property identified by name to the given 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 asynchronous nature of the underlying Wayland protocol.

See also windowProperty, windowProperties, and windowPropertyChanged.


object windowProperties()

Returns an object containing all shared properties of this application window.

See also setWindowProperty.


var windowProperty(name)

Returns the value of this application window's shared property identified by name.

See also setWindowProperty.
