    \brief Contains status information in your app.

    The common way of using StatusBar is in relation to \l ApplicationWindow.

    Note that the StatusBar does not provide a layout of its own, but requires
    you to position its contents, for instance by creating a \l RowLayout.

    If only a single item is used within the StatusBar, it will resize to fit the implicitHeight
    of its contained item. This makes it particularly suitable for use together with layouts.
    Otherwise the height is platform dependent.

    \code
    import QtQuick.Controls 1.2
    import QtQuick.Layouts 1.0

    ApplicationWindow {
        statusBar: StatusBar {
            RowLayout {
                anchors.fill: parent
                Label { text: "Read Only" }
            }
        }
    }
