0 0 1 minute read

In this article we will see how to set margin to a progress bar. In order to add margin to progress bar we have to change the style sheet code for the chunk i.e the internal part (loading bar) of the progress bar.

Below is the style sheet code.

QProgressBar::chunk 
{
background-color: pink;
margin: 5px;
}

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(150, 150, 200, 30) 
  
        # set value to progress bar 
        bar.setValue(40) 
  
        # setting alignment to center 
        bar.setAlignment(Qt.AlignCenter) 
          
        # setting background color and margin 
        bar.setStyleSheet("QProgressBar::chunk "
                          "{"
                          "background-color: pink;"
                          "margin: 5px;"
                          "}") 
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
