Dark KDE theme badly applied

Mon Feb 03, 2020 6:35 pm
Goodmorning everyone.
I recently installed Packet Tracer 7.3 on my PC with Manjaro and KDE Plasma, noting that it works almost perfectly.
I say almost because, as you can see from the screenshot, the dark theme that I installed in my workspace (Pear Dark) completely ruins the application's color palette and, to make matters worse, makes some writings practically invisible (Under the computer in the middle of the screen SHOULD be written "PC-PT PC0").

Image

So I wonder: given that in Packet Tracer there is no option to disable the dark theme in-app, is there the possibility of overriding by imposing a light theme (Breath, for example)?
Thanks in advance for the help.

PS: I have already tried to start the software with the command
Code: Select all
QT_STYLE_OVERRIDE=Breath /opt/packettracer/packettracer %f
or to right click on the title bar of the application and from there "Other actions > Configure specific settings for application > Title bar color scheme: Force Breath", but the result does not change

The theme you installed is not one we made, you need to report it's bugs to the author of it in https://store.kde.org


Currently running Kubuntu 20.04, Plasma 5.18.5, Frameworks 5.68.0, Qt 5.12.8, kernel 5.4.0-46
FWIW: it is always useful to state the exact Plasma version and distribution when asking questions in this forum, makes it easier for us to help ...

Yes I know.
In fact, I am not asking for support on the particular theme, but how to force the use of another theme in a specific application.

I don't think this is possible, the applications should use the installed active theme, if you want a different one, it will only work for all applications of this user.
So the only other option I see is to switch to a different user for a different theme and use that specific application there.

Your screenshot shows the standard theme that Packet Tracer uses, so your selected theme is not being used by it at all.
The application uses its own Qt libraries, and may not support theming , other than what is available in the program's settings.

Assuming that you are using a global plasma theme, and not just the Pear Plasma style, there is also a Pear color theme installed that might be tweakable to fix the font coloring you are seeing.
