Description gal.mateo 2024-12-20 04:48:58 UTC

Created attachment 176779 [details]
py_side6_version.py

The following Github project contains a simple draggable window written in PyQt6:
https://github.com/Khufos/Pyqt6-Title-hide-and-window-move
I even reproduced the PySide6 version to make sure that the problem is not with PyQt6.
You can find the PySide6 version in the attachment.

The expected behavior is that the window is draggable by clicking and holding it.
It works fine on Windows 11 / Arch Linux (XFCE) / Arch Linux (LXDE) / Arch Linux (Gnome)
But it does not work at all on Arch Linux with KDE.

The example program doesn't work for me:

QIODevice::read (QFile, "bar_hide.ui"): device not open
Designer: An error has occurred while reading the UI file at line 1, column 0: Premature end of document.
Traceback (most recent call last):
  File "/home/nate/Desktop/test.py", line 30, in <module>
    window = Page()
  File "/home/nate/Desktop/test.py", line 12, in __init__
    self.ui = loader.load(ui_file, self)
              ~~~~~~~~~~~^^^^^^^^^^^^^^^
RuntimeError: Unable to open/read ui device

Regardless, since clearly it does run for you, can you reproduce the issue in a Plasma X11 session? Or is it broken there too?

And when you say it works in other environments, do you mean that the exact same program works as expected in those environments?
