For eg. I installed Blur-glassy theme today to check with all options selected in my Fedora 40 installation. Still I needed to install the blur option separately and colors too. After everything still Dolphin and Discover do not look anything like the picture shown.
I have seen this while trying out many themes. They either partially deploy or sometimes not.
Is it because they were built for KDE 5 and this is 6 or something?
Kvantum allows much more complex theming, compared to what you can achieve with regular Qt themes, but whether it’s worth it or not, that’s for you to decide
I hear that. I used to be heavily into theming/skinning my desktop back when Windows XP hit the scene, but nowadays I just like something consistent. I guess I’ll probably test it out on one of my testing units and see if I like it.
Complexity doesn’t imply inconsistency, but i hear you. Find a theme you like, and if it needs kvantum, then try it out, and if not, then don’t. It’s not like it’s required to enjoy Plasma
Regular Qt themes are compiled C++ programs that use the QStyle API to alter the look of Qt applications. They can do just about anything, but obviously require code to create. Being compiled programs also means they can’t be portably distributed. They have to be recompiled for every different Qt version and architecture.
Kvantum is just one of those themes, and it uses its code to load and display much simpler SVG-based themes. Kvantum themes are actually much less complex than regular Qt themes, which is the whole point, since that makes them significantly simpler to create and much more portable, which is why they’re so popular. The vast majority of Qt themes nowadays are made for Kvantum. Before Kvantum, it was mostly the less powerful QtCurve. Regular themes can do a lot of things Kvantum themes can’t, but Kvantum is usually good enough.
