PyQt5 – Changing border of Progress Bar
  • Last Updated : 22 Apr, 2020

In this article we will see how to change or set the border to a Progress Bar. By default, PyQt5 provides border to the progress bar but we can change it according to our convenience. Below is how default border progress bar vs styled border progress bar looks like.

In order to do this we have to change the CSS style sheet of the progress bar with the help of setStyleSheet() method.

Syntax :

bar.setStyleSheet("QProgressBar"
                  "{"
                  "border : 4px solid green"
                  "}")

Argument : It takes string as argument.



Action performed : It will add border to the progress bar.

Below is the implementation




# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
        # creating progress bar
        bar = QProgressBar(self)
  
        # setting geometry to progress bar
        bar.setGeometry(200, 100, 200, 30)
  
        # setting the value
        bar.setValue(70)
  
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # adding border to the progress bar
        bar.setStyleSheet("QProgressBar"
                          "{"
                          "border : 4px solid green"
                          "}")
  
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
