I use helium theme and try to set the background color of a single groupbox.
Changing the general setting by using --panel-background-color works,
but I cannot find out how to do it only for a single groupbox.
Tried .myGroupbox .helium.small . c-groupbox …
and many other combination,
but it did not work
I double checked, can see, that the stylename=“custom-bg” is in the code if I use the F12 in Chrome…
Vladimir will play around with it. I sent him the xml part for that.
If he finds a solution, I will update it here.
Have you added the implementation of custom-bg to the helium theme extension? In my case, I simply added it to the helium-ext.scss. As an option, run ./gradlew deployThemes to make sure that changes are deployed and refresh a page without cache.
