I am trying to create a GUI application using Pyqt5. The issue I am facing is that the code is running well but record window is not opening. I am attaching the whole code below and the snippet of the function which I am referring to. I have tried going through the whole code but haven't found any flaws in the same.

import sys
from random import randint

from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow, QPushButton, QVBoxLayout, QWidget
import time
#from libsonyapi.camera import Camera
#from libsonyapi.actions import Actions
#from pysony import SonyAPI, ControlPoint, common_header
#search = ControlPoint()
#cameras =  search.discover(1) 
#camera = SonyAPI(QX_ADDR=cameras[0])
 # create camera instance
#camerass = Camera()

        # THIS BUTTON IS USED TO START RECORDING #

app = QApplication(sys.argv)
w = MainWindow()
w.show()

And the function is

class recording(QWidget):


    def __init__(self):
        super().__init__()
        layout = QVBoxLayout(self)
        
        # THIS BUTTON IS USED TO START RECORDING #
        start_recording_button = QPushButton(" START RECORDING ")
        start_recording_button.clicked.connect(self.start_recording)
        layout.addWidget(start_recording_button)

        # THIS BUTTON IS USED TO STOP RECORDING #
        stop_recording_button = QPushButton(" STOP RECORDING ")

In your code you never create MainWindow3 where the recording class / window would be created after clicking the "RECORDING" button.

After creating MainWindow3 the recording window shows up after button press. To test this you can just replace

w = MainWindow()

with

w = MainWindow3()

in your "main" (third last line)

I have run it in my system and made a few changes. I am pasting the code below.

from random import randint

from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow, QPushButton, QVBoxLayout, QWidget
import time
#from libsonyapi.camera import Camera
#from libsonyapi.actions import Actions
#from pysony import SonyAPI, ControlPoint, common_header
#search = ControlPoint()
#cameras =  search.discover(1) 
#camera = SonyAPI(QX_ADDR=cameras[0])
 # create camera instance
#camerass = Camera()
