the Gallery example from qt.labs.controls
http://doc.qt.io/qt-5/qtlabscontrols-gallery-gallery-qml.html
defines the ApplicationWindow this way:

ApplicationWindow
<http://doc.qt.io/qt-5/qml-qt-labs-controls-applicationwindow.html> {
    id: window
    width: 360
    height: 520
    visible: true
    title: "Qt Labs Controls"


My question is about the width and height.

I'm using it only for mobile APPs on Android and iOS

On a mobile device the ApplicationWindow always has to fill the entire
available space,
so it doesn't make sense to start with a fixed size width / height I think

what's recommended ?

should I remove width and height settings and let Qt calculate without ?

Or should I set the width and height from QScreen ?
this works:

context->setContextProperty("myScreen",qApp->primaryScreen());


and then I can use

width:myScreen.size.width // or better .availableSize.width ?


have tested: size is correct and also changes if rotating from portrait
to landscape

thx for infos
