Qt Quick Controls 2 Material size too big on desktop

[jiancaiyang]

Although Qt Quick Controls 2 designs well, and Material style fascinating, however when we use in desktop, we can bear because the control is too big. I wonder is there any way to adjust the size of control JUST IN A LINE OF CODE, or to configure it?

You can tweak the automatic scaling http://doc.qt.io/qt-5.10/qtquickcontrols2-highdpi.html

Or see QT_SCALE_FACTOR usage described in http://doc.qt.io/qt-5/highdpi.html I think this is exactly what you want :-)

cause this high dpi mode works not well on desktop

This is screenshot for Lubuntu.

1. Use QCoreApplication::setAttribute( Qt::AA_EnableHighDpiScaling ); before QGuiApplication app( argc, argv ); -> Useless
2. Commented out QCoreApplication::setAttribute( Qt::AA_EnableHighDpiScaling ); -> Useless
3. Set QT_AUTO_SCREEN_SCALE_FACTOR=1 into "Environment Variable" panel in Qt Creator -> Useless

I need further help.

This is what Qt Quick Controls 2 demo "gallery" looks like:

I know Qt Quick Controls 2 is targeting mobile devices, but in fact Material theme looks good even in desktop. We need some utility to configure the look'n' feel for Material style.
BTW: I don't like to make a copy and change the controls one by one.

While it is not an utility, there is the conf file described in docs

The Material Design guidelines specify a dense variant for desktop, but it was not (yet?) implemented for Qt Quick Controls 2. This was simply mainly due to lack of resources, but there have been also some performance concerns. Anyway, feel free to vote and/or comment QTBUG-51109 if you think it should be prioritized higher.

@jpnurmi I wish it could be implemented.
