Slide horizontal setting widgets in Krita

[bogdancovaciu]

Hello,

By default, the brush Opacity and Size widgets in Krita look like this:

With latest Adwaita-qt, kcoreaddons 5.87 and qt5 5.15.2 i get this:

The slide goes on vertical, squeezed, instead of horizontal.

Reproducible on KDE Plasma and Gnome while using the profile export KRITA_NO_STYLE_OVERRIDE=1 because i want to get rid of the default Fusion style used for it.

This is weird, because I have QProgressBar in my demo/test application and it is correct (both variants). Also, when I check the source code of QProgressBar, I can see that, when the orientation is horizontal, it updates QStyleOption->state, which is what we check in order to distinguish between horizontal and vertical orientation.

Have you seen similar issue in some other application?

Actually Krita is the only one that has those Brush option sliders. Not sure if are related to QProgressBar, or simply something only they use for horizontalSlider > QSlider and doesn't match, only if using their default Fusion style or the Breeze one. Will try to contact one of the developers from Krita and see if i get a hint.

I will keep digging, because it works with Fusion and Breeze so there actually might be something wrong with Adwaita.

The only real issue is when booting in Gnome, as i always test between KDE Plasma and Gnome, not mixing them, and i prefer to keep things consistent. But even in KDE Plasma i prefer to use Adwaita, has the best contrast for my eyes, and each element a proper "footprint" on screen. One thing i notice in preview, the difference of those sliders, but they render properly.

Only Krita has them somehow acting funky. Edit: Found only this on the bug report list https://bugs.kde.org/show_bug.cgi?id=440637

Not sure if related tho, or how that could influence the render of Adwaita.

Should be fixed with https://github.com/FedoraQt/adwaita-qt/commit/85670f8f2f61fd10f867d55555282d0951925160.
