QT6 flatpak install

QCAD Version: 3.32.9
Operating System: Linux Mint

I’ve installed the latest QT6 flatpak package - qcad-3.32.9-pro-linux-qt6-x86_64.flatpak via the terminal using - flatpak install /home/pete/Downloads/qcad-3.32.9-pro-linux-qt6-x86_64.flatpak. I’m now trying to add themes from my previous Qcad version to the QT6 theme folder, but I can’t find it, I also can’t even find the executable. The Qcad about dialogue box shows the config file location, which I’ve found, it also shows a data folder, which is empty. The Linux menu launcher for the QT6 version isn’t much help either as there is no theme folder in the org.qcad.QCAD path.

I’ve finally found the theme folder. it’s in /var/lib/flatpak/app/org.qcad.QCAD/current/active/files jeez, why so hidden ??

…and you need Root permission to copy files into the themes folder !
