In this article we will see how we can create the progress bar in PyQt5. In order to create progress bar object we will use QProgressBar.
A progress bar is a graphical control element used to visualize the progression of an extended computer operation, such as a download, file transfer, or installation. Sometimes, the graphic is accompanied by a textual representation of the progress in a percent format.
Syntax :
pbar = QProgressBar(self)
Code :
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5.QtGui import * from PyQt5.QtCore import * import sysimport time class Example(QWidget): def __init__(self): super().__init__() # calling initUI method self.initUI() # method for creating widgets def initUI(self): # creating progress bar self.pbar = QProgressBar(self) # setting its geometry self.pbar.setGeometry(30, 40, 200, 25) # creating push button self.btn = QPushButton('Start', self) # changing its position self.btn.move(40, 80) # adding action to push button self.btn.clicked.connect(self.doAction) # setting window geometry self.setGeometry(300, 300, 280, 170) # setting window action self.setWindowTitle("Python") # showing all the widgets self.show() # when button is pressed this method is being called def doAction(self): # setting for loop to set value of progress bar for i in range(101): # slowing down the loop time.sleep(0.05) # setting value to progress bar self.pbar.setValue(i) # main methodif __name__ == '__main__': # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Example() # start the app sys.exit(App.exec()) |
Output :
