PyQt5 – Background Color of Progress Bar

Last Updated : 22 Apr, 2020

When we create a progress bar, by default there is no background color set to it, although the bar color is of green. In this article we will see how to set the background color to the progress bar. Below is the representation of normal progress bar vs the progress bar which has background color.

In order to do this we have to change the CSS style sheet using setStyleSheet method, below is the style sheet.

QProgressBar
{
background-color :lightblue;
border : 1px;
}

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(30) 
  
        # setting alignment to center 
        bar.setAlignment(Qt.AlignCenter) 
  
        # setting background color 
        bar.setStyleSheet("QProgressBar"
                          "{"
                          "background-color : lightblue;"
                          "border : 1px"
                          "}") 
  
  
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
