UI Themes?

[Perdrix]

My application currently uses the "Fusion" style, but I've been asked if I can add "Themes" like the Windows Dark and Light Themes.

Is there such support in Qt?

Hi
Nope. There is no buildin Dark theme for QWidgets.
There are solutions like

QML has

Light/dark appearance including runtime changes will be supported from Qt 6.5 onwards.

@Axel-Spoerl Now that 6.5 is out where can I find the details about this support please?

Many thanks
David

@Perdrix
Basically the platform theme knows about the appearance.
We have changed the appearance property to the more meaningful name colorScheme last week.
See here: https://codereview.qt-project.org/c/qt/qtbase/+/460162

@Axel-Spoerl Will this apply to Widgets as well as Qt Quick?

Thanks
David

[Axel Spoerl]

Yes, it will apply to both!

@Axel-Spoerl 👏Thanks a lot
