In this article we will see how to change the color of process bar. By default, the color of process bar is green although PyQt5 allows us to change the color using the style sheets. In order to do this we will use setStyleSheet method and will edit the CSS chunk file of process bar.
Syntax :
bar.setStyleSheet("QProgressBar::chunk " "{" "background-color: red;" "}")Action performed : It will change the color of process bar.
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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(70) # changing the color of process bar bar.setStyleSheet("QProgressBar::chunk " "{" "background-color: red;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
