I'm trying to make my python code interact with my QML file, but my findChild() function keeps returning None, I also tried findChildren() and it returned []. Browsed other questions but nothing I found worked. Here is my python code:
import sys
import os
from PySide2.QtGui import QGuiApplication
from PySide2.QtQml import QQmlApplicationEngine
from PyQt5 import QtCore, QtGui, QtQml
def main():
app = QGuiApplication(sys.argv)
engine = QQmlApplicationEngine()
engine.load(os.path.join("ui", "main.qml"))
screen = engine.rootObjects()[0]
print(screen)
#returns <PySide2.QtGui.QWindow(0x1db42e7e2a0, name="main_window") at 0x000001DB434AD608>
print(screen.findChild(QtCore.QObject, "rec_body"))
#returns None
if not engine.rootObjects():
sys.exit(-1)
sys.exit(app.exec_())
if __name__ == "__main__":
main()
And the QML (gerenerated via QT Creator, I had to manually add the objectName but it didn't solve my problem):
