In PYQT5, I want to increase the progress of the round progress bar in UI after every 10 minutes by using PyQt5 for 90 minutes. I have tried 2 methods 1st by time.sleep() and 2nd by Qtimer.
1st method "time.sleep"
import sys
import os
from datetime import time
import qdarkstyle
from ui_main import *
progress_val = 0
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
# APPLY QDARKSTYLE THEME
self.setStyleSheet(qdarkstyle.load_stylesheet_pyside2())
# SET PROGRESS BAR VALUE
self.ui.progressBar.rpb_setMaximum(420)
# SET PROGRESS BAR STYLE
self.ui.progressBar.rpb_setBarStyle('Donet')
# SET PROGRESS BAR LINE COLOR
self.ui.progressBar.rpb_setLineColor((0, 170, 255)) # ARGUMENT RGB AS A TUPLE
# CHANGING THE PATH COLOR
self.ui.progressBar.rpb_setPathColor((255, 30, 99))
# SET PROGRESS BAR TEXT COLOR
self.ui.progressBar.rpb_setTextColor((233, 30, 99)) # ARGUMENT RGB AS A TUPLE
# SET PROGRESS BAR STARTING POSITION
# North, East, West, South
self.ui.progressBar.rpb_setInitialPos('West') # WEST AS STARTING POSITION.
# SET PROGRESS BAR TEXT TYPE : VALUE OR PERCENTAGE
# Value, Percentage
self.ui.progressBar.rpb_setTextFormat('Percentage')
# SET PROGRESS BAR FONT
self.ui.progressBar.rpb_setTextFont('Arial')
# TEXT HIDDEN
self.ui.progressBar.rpb_enableText(False)
# SET PROGRESS BAR LINE WIDTH
self.ui.progressBar.rpb_setLineWidth(10)
# PATH WIDTH
self.ui.progressBar.rpb_setPathWidth(15)
# SET PROGRESS BAR LINE CAP
# RoundCap, SquareCap
self.ui.progressBar.rpb_setLineCap('RoundCap')
# LINE STYLE
# DotLine, DashLine
self.ui.progressBar.rpb_setLineStyle('DotLine')

time.sleep(60)
# Reset progresses if the maximum value is reached
if progress_val > 420:
progress_val = 0;
# Increase value every 60 ms
progress_val += 1

Output:
In the first method, I used timer.sleep() but the UI got stuck.
2nd method "QTimer"

progress_val = 0

after implementation, the code progress is not made in the expected time. for example, I gave 1 minute means timer.start(6000) but the progress bar takes longer than 1 minute to increase.

I think you have the right idea with using the QTimer, But I would just use the timer for it's timed signal emitter, and update the progress bar based on the system clock using time.time().
like this:
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.start_time = time.time()
...
self.show()
self.timer = QTimer()
self.timer.timeout.connect(self.progress)
self.timer.start(1000) # this will emit every second
def progress():
if time.time() - self.start_time >= 420: # this would be 420 seconds
self.start_time = time.time()
self.ui.progressBar.rpb_setValue(time.time() - self.start_time)
...
