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 ())
