PyQt5 – Background Color of Progress Bar
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 ()) |
