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 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( 70 )
# changing the color of process bar
bar.setStyleSheet("QProgressBar::chunk "
"{"
"background - color: red;"
"}")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
