I am trying to create a graphical user interface which will run on a QT container on Torizon.

I have tried two different methods to create the graphical user interface. For method 1 I generated the GUI using a QML file and for method 2 I used the QWidgets. I found out that generating a GUI with QWidgets is much faster. Am I doing something wrong with loading the QML file or is a GUI with Widgets just faster compared to a GUI with a QML file?

For both applications, I have used python 3.10.9 together with PySide2. I am running the application on Torizon on a Toradex IMX8 module.

The code which I use to load the QML file in Python is written down below. This code is the same code as the sample code which Torizon provides when you select in Visual Studio Code that you want to create a QT Python Application with QML.

import sys
import os
import PySide2
from PySide2.QtWidgets import QApplication
from PySide2.QtCore import QUrl, QObject
from PySide2.QtQuick import QQuickView

if __name__ == "__main__":
    print("Hello world!")

    app = QApplication(sys.argv)

    view = QQuickView()

    qml = QUrl("mainwindow.qml")

    view.setSource(qml)
    view.show()

    sys.exit(app.exec_())

Thank you!
