In this article we will see how we can set gradient color to the progress bar. Below is how normal color progress bar looks like vs the gradient color progress bar looks like.

In order to do this we have to change the CSS style sheet, below is the code for style sheet.

QProgressBar::chunk 
{
border : 1px solid black;
background: QLinearGradient( x1: 0, y1: 0,
                             x2: 1, y2: 0, 
                          stop: 0 #000fff, 
                          stop: 1 #ff000f );
}

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, 150, 200, 30)
  
        # set value to progress bar
        bar.setValue(30)
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # setting gradient color to progress bar
        bar.setStyleSheet("QProgressBar"
                          "{"
                          "border : 1px solid black;"
                          "background: QLinearGradient( x1: 0, y1: 0,
                                                        x2: 1, y2: 0,
                                                    stop: 0 # 00ffff,
                                                    stop: 1 # ff000f );"
                          "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
