I can't use MEMS-studio under KDE/Plasma (linux)

[zmogas]

Hello,

in KDE/plasma environment I can't use MEMS-studio because it doesn't show file dialogs.

For example: MEMS-studio is connected to the STEVAL-MKI109V3 board, in "Advanced Features" -> "FSM" I click the "Load state machine from file“ button, but nothing happens, the file dialog does not appear.

Is there any solution to allow MEMS-studio to work properly in the KDE/plasma environment?

When I run MEMS-studio from the command line I get this output from the console:

Hi @zmogas ,

Welcome to ST Community!

Thank you for using MEMS Studio, we are sorry you are facing some issues. MEMS Studio is officially supported on Ubuntu Linux 20.04 or higher however it shall also run on Arch Linux.

File dialogs should work correctly when application is started using provided mems-studio.desktop file. If this is not the case, you can start the application from console using this command:

QT_QPA_PLATFORMTHEME=gtk3 QT_QPA_PLATFORM=xcb /opt/mems-studio/bin/mems-studio

[zmogas]

It works, thanks!

Yes, I tried running the mems-studio.desktop file, but the file dialogs didn't show up either.

The exported variable "QT_QPA_PLATFORM=xcb" fixed the problem with file dialogs.

But I found it strange that MEMS-studio (which uses Qt libraries) does not work out of the box in Qt-based KDE/plasma environment, but it works correctly in Ubuntu, where the graphical environment is GTK...
