Yaru: Suggestion: develop yaru-qt, in the style of adwaita-qt

[coxackie]

This is not a bug per-se. I love Yaru, but it does play as well as Adwaita does via adwaita-qt (https://github.com/FedoraQt/adwaita-qt) for Qt applications. I tried to use adwaita-qt with Yaru, but for the "standard" (not dark or light) theme the title bars of Qt applications appear greyish with white text - it seems that the color is not picked up. (I can provide screenshots if needed.)

I was wondering whether, since you want to keep as close as Adwaita upstream as possible, you would be willing to fork adwaita-qt into something like yaru-qt.

Hey, thank you, this is an idea to explore for sure

[coxackie]

Some screenshots to provide evidence. I am using Yary and adwaita-qt. First screenshot:

It shows the normal Yaru theme - you see Files and Spotify with the correct title/headerbar colors, and RStudio and Flacon (qt) with grey title-bars.

The same set-up with Yaru-light or Yaru-dark playes well with adwaita-qt:

I guess this is related to the fact that Adwaita only has the two flavours (light and dark).

But even if this is resolved in adwaita-qt, it still uses Adwaita theming. It would be great to get a native Yaru feeling.

I think this only happens if you switch between all three themes. It happens for server side decorated apps.
If you only switch between yaru and yaru-dark it should not happen ( I think )

[coxackie]

well, when I first noticed it (situation like the first screenshot) I have been using yaru for a very long time, I was not using yaru-light or yaru-dark at all. Although I do agree that things get weird once you start changing through themes - going from yaru to yaru-dark changes SSD to the correct color, and back to yaru keeps them as such. At any rate, there is clear inconsistency. (Only to be expected, of course, since once cannot hope that yaru and adwaita-qt should work well together)

[coxackie]

I wonder if it would be a good idea to actually open an issue at adwaita-qt on this. It may be the case that they can handle the themes in a unified way, since yaru will be following adwaita closely. What do you guys think?

[Feichtmeier]

@coxackie knowing the guys a bit and this is def. not a good idea :)

[coxackie]

lol... ok. keeping my cool then - nothing to see here.

[asegarra]

Would love to see this, in conjunction with packaging QGnomePlatform.

[coxackie]

Yeah, I know, but seems that the issue has not gathered enough traction...

[fouzan14]

Is it not easy to change and modify adwaita-qt to yaru-qt, I mean since yaru itself is based on tweaks to Adwaita right?
I just want consistency and this to really happen: https://discourse.ubuntu.com/t/having-yaru-as-a-global-ubuntu-flavor-theme/18470

Is something planned for this?

[clobrano]

As far as it is related to GTK application, it is not that hard (see #2331), but for different toolkits is harder. It would be great if anyone interested could work on this :)

[coxackie]

I guess this would require someone knowledgeable in QT/C++ (to manage through the code of adwaita-qt) and the yaru theme. Do the developers have someone in mind? Presumably Ubuntu would be quite interested in such consistent experience.
