Welcome folks today in this post we will be building a loading bar circular spinner gif animation in pyqt5. All the full source code of the application is shown below.

Get Started

In order to get started you need to install the following library using the pip command as shown below

pip install pyqt5

After installing this library make an app.py file and copy paste the following code

app.py

import sys 
from PyQt5 import QtCore, QtGui, QtWidgets 
from PyQt5.QtGui import QMovie 
from PyQt5.QtCore import Qt 
  
  
class LoadingGif(object): 
  
    def mainUI(self, FrontWindow): 
        FrontWindow.setObjectName("FTwindow") 
        FrontWindow.resize(320, 300) 
        self.centralwidget = QtWidgets.QWidget(FrontWindow) 
        self.centralwidget.setObjectName("main-widget") 
  
        # Label Create 
        self.label = QtWidgets.QLabel(self.centralwidget) 
        self.label.setGeometry(QtCore.QRect(25, 25, 200, 200)) 
        self.label.setMinimumSize(QtCore.QSize(250, 250)) 
        self.label.setMaximumSize(QtCore.QSize(250, 250)) 
        self.label.setObjectName("lb1") 
        FrontWindow.setCentralWidget(self.centralwidget) 
  
        # Loading the GIF 
        self.movie = QMovie("loader.gif") 
        self.label.asetMovie(self.movie) 
  
        self.startAnimation() 
  
    # Start Animation 
  
    def startAnimation(self): 
        self.movie.start() 
  
    # Stop Animation(According to need) 
    def stopAnimation(self): 
        self.movie.stop() 
  
  
app = QtWidgets.QApplication(sys.argv) 
window = QtWidgets.QMainWindow() 
demo = LoadingGif() 
demo.mainUI(window) 
window.show() 
sys.exit(app.exec_())

Now if you execute the python script by typing the below command as shown below

python app.py
