Port to pyside6?

[doragasu]

I want to install this on Archlinux, that does not have pyside2 (Qt5) on official repositories, but pyside6 (Qt6). Could it be possible getting a release working with pyside6?

Thanks for the plugin!

FreeCAD actually seems to provide a wrapper for PySide which should get whatever version is available, so I've switched to using that now. Not sure if my GUI code is actually PySide6 compatible though, let me know if this works for you.

Maybe I'm just missing something, but since I installed it, FreeCAD shows this on startup:

15:15:01  During initialization the error "No module named 'PySide2'" occurred in /home/jalon/.local/share/FreeCAD/Mod/free2ki_v1-0/free2ki/InitGui.py
15:15:01  Please look into the log file for further information

And I do not have the free2ki workbench.

EDIT: Oh I see you have already performed changes, let me check and report, thanks!

The export works great! Unfortunately, the Set Materials throws this exception:

15:29:32  Running the Python command 'Free2KiSetMaterials' failed:

'PySide6.QtGui.QFontMetrics' object has no attribute 'widthChar'

That one should be fixed as well now.

Thanks.

It somehow works, but not cleanly. I can open the dialog and change materials. But when I hover the mouse over the materials dialog, these ugly logs appear:

Error calling Python override of QWidget::paintEvent(): Traceback (most recent call last):
  File "/home/jalon/.local/share/FreeCAD/Mod/free2ki/free2ki/f2k_commands.py", line 381, in paintEvent

    ~~~~~~~~~~~~~~^^^^^^^^^^^^^

QBackingStore::endPaint() called with active painter; did you forget to destroy it or call QPainter::end() on it?

And when exiting FreeCAD after using this dialog, it segfaults, I suppose it must be related:
