Qt 5.6 - qt.labs.controls - ApplicationWindow width / height

[ekkescorner]

UseCase: mobile APP Development for Android / iOS using TechPreview of new QtQuickControls2
There's a specific Gallery Example demonstrating use of qt.labs.controls
http://doc.qt.io/qt-5/qtlabscontrols-gallery-gallery-qml.html

ApplicationWindow from qt.labs.control namespace is defined this way:

ApplicationWindow {
    id: window
    width: 360
    height: 520
    visible: true
    title: "Qt Labs Controls"

My qestion is about the width and height

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 will give me correct size and also changes if rotating from portrait to landscape:

main.cpp:
context->setContextProperty("myScreen", qApp->primaryScreen());

QML:
width: myScreen.size.width

If this is recommended next question: should I use myScreen.availableSize.width instead of myScreen.size.width

thx for infos

Qt shows windows fullscreen/maximized [*] by default when appropriate. Thus, the desired window size specified in the Gallery example does not make any difference on mobile platforms, but it does on desktop platforms where apps run in windowed mode.
