How to implement progress bar in Qt Desinger?

Question

Python

Hello everyone, I came across the fact that there is no good example on the Internet for implementing a progress bar with binding to downloading using Qt5. In my program, I need to make several buttons with downloading files, but I can’t find information anywhere on how exactly the download process can be implemented so that the user sees it. At the moment, I think that my download functions will not work, but I'll attach it anyway.

Other functions are based on this function:

def save_rutoken(link3):
    filename = link3.split('/')[-1]
    print (filename)
    r = requests.get(link3)
    open(filename, 'wb').write(r.content)
    save_rutoken = tk.Label(win, text='Рутокен скачан', fg='green', bg='#80A6FF', font=('Arial',12))
    save_rutoken.pack()
    save_rutoken.place(x=190, y=37)
    p = Process(target=save_rutoken)
    p.start()
    print('something')

link3 is a variable containing the download link.

this is how the interface itself looks visually:


interface code:

from multiprocessing import Process
from PyQt5 import QtCore, QtGui, QtWidgets
import requests

link3 = 'https://download.rutoken.ru/Rutoken/Drivers/Current/rtDrivers.exe'

class Ui_UTM(object):
    def setupUi(self, UTM):
        UTM.setObjectName("UTM")
        UTM.resize(547, 303)
        UTM.setSizeGripEnabled(False)
        UTM.setModal(False)
        self.download_rutoken = QtWidgets.QPushButton(UTM)
        self.download_rutoken.setGeometry(QtCore.QRect(20, 10, 121, 51))
        self.download_rutoken.setObjectName("download_rutoken")

An example of progress output in Qt is right here . See the requests documentation for an example of load control . Combining it into one program is not tricky.
