[SOLVED] I can't set plasma style for own application

OS: Arch Linux
Kernel: 4.13.8-1

Hi.
I cannot set the Breeze style for my application written in PyQt5.

I have appended a line "export QT_QPA_PLATFORMTHEME=qt5ct" to my .zshrc file, rebooted and set Breeze style with qt5ct:

All applications installed with pacman have Breeze theme, but when I run my PyQt5 application it has the default theme (fusion?):

Do you have any idea how I can fix it? GUI was made with Qt Designer. As you can see, I've got there a Breeze style (look at these RadioButtons):

I've tried to run an application like ./untitle.py -style <something> but it didn't work too.

Re: [SOLVED] I can't set plasma style for own application

Is the GUI of your application done with QWidgets or QtQuick?

Re: [SOLVED] I can't set plasma style for own application

What if you "export QT_STYLE_OVERRIDE=Breeze" for at least that application?

It hasn't helped.

Re: [SOLVED] I can't set plasma style for own application

Did you install pyqt with pacman or with pip?

With pacman (python-pyqt5 package)

Tabs look exactly the same in ReText and in my application (when in Qt Designer and other apps like QTerminal tabs have 'x' in the circle).

Are you 100% sure you don't have any other pyqt installation on your system? what's the output of

python -c 'import PyQt5; print(PyQt5.__file__)'

?

Re: [SOLVED] I can't set plasma style for own application

I listed all packages installed with pip and I had PyQt5... I removed this and now it works like a charm.

Well, I don't remember when I've installed this

Thanks a lot guys!
