Don't understand how works width and height attributes of Window QML Type

[Damalo_02]

Hello,
I'm trying to use QML for graphic part of an Android app. I don't understand how works width and height attributes of Window QML Type.

For example, if I set the width and height to 10, the whole screen of my phone appears in blue (the phone I am testing on has a screen size of 960 x 540. ), any idea why?

Thanks

the top level item is stretched to fill the whole screen, at least on Android and iOS.

Nothing you can do about it, its mandatory by the OS

Ok thanks a lot, that's what I wanted to know.

So it means that width and height attributes are useless in top level item?

Not necessarily useless but rather unnecessary.
You should define it anyway, in case you end up compiling your project for desktop as well ;-)

that depends on the underlying platform (as @J-Hilk pointed out)
For example the same applies for EGLFS under Linux, but not for X11 under Linux.

Okay I see, thanks a lot for your answers :)
