Hi,
I don't run a Qt window manager such as KDE, but Xfce.
How can I change the menu font and font size of QCad? Looking at ldd it's build on Qt5, and while Qt5 has dropped the qtconfig of Qt4 which many people already complained about, I also tried the 3rd party tool qt5ct, but changing the fonts there did not have any effect on QCad.
Beside that it doesn't seem to respect the Xfce fonts sizes of course.

Probably best to do some online research about Qt applications in general, your particular window manager and font sizes. Feel free to post back if you find out anything.
