Beautiful design documentation for example Qt. Do you have ready funds?

Question

Qt

I'm trudging from Qt docks, for example: doc.qt.io/qt-4.8/qobject.html
After everything I've seen before, especially doxygen, I want to do at least as good for my big project.
The question is whether such ready-made CCMs have already appeared for drawing up documentation for the code (with examples, classes, etc.).
Now I use doxygen, but I'm ready to spend a lot of time rewriting for something else.
I saw that doxygen can provide in xml format, maybe there are some plugins, for example for WordPress or other themes for html?
Or maybe it will be easier to do the xml parsing yourself and file the plugin for WordPressa?

Answer 1

https://doc-snapshots.qt.io/qdoc/01-qdoc-manual.html - they honestly write that this was used for Qt.
