PyQt5 - Python | QApplication.setStyle not working

Question

I am trying to set custom style to my PyQt5 application using the setStyle() method but it doesn't work.

I am also not entirely sure about where this should be put.

In my main I tried doing :

if __name__ == '__main__':

    QApplication.setStyle("mac") #here
    app = QApplication(sys.argv)
    splash_pix = QPixmap('../resource/logo.png')
    start = time.time()
    splash = QSplashScreen(splash_pix, Qt.WindowStaysOnTopHint)
    splash.show()
    while time.time() - start < 1:
        time.sleep(0.003)
        app.processEvents()
    ex = Fy360()
    splash.finish(ex)
    sys.exit(app.exec_())

Edit : Upon importing from PyQt5.QtWidgets import QStyleFactory and printing the QStyleFactory.keys() I gotthe output as:

[u'Windows', u'Fusion']

why are there only these options?

Whats going wrong here?

You can run the following command: from PyQt5.QtWidgets import QStyleFactory; print(QStyleFactory.keys()) and show us what you — eyllanesc

@eyllanesc I'm sorry I did a mistake, I tried to print the keys in a function hence I got no output but when I tried it in my main I got this [u'Windows', u'Fusion'] — Sapnesh Naik

Some styles are dependent on the OS, others are not, for example the Mac style is only for Mac OS, or for example fusion is compatible for several OS. — eyllanesc

Some styles are dependent on the OS, others are not, for example the Mac style is only for Mac OS, or for example fusion is compatible for several OS.

Some styles (for example gtk) can be configured as follows:

Based on the discussion :

Install qt5-styleplugins and qt5ct
Set environment variable in /etc/environment QT_QPA_PLATFORMTHEME=qt5ct
Restart the system
Start qt5ct and select gtk2
