PyQt5 – Capsule shaped Progress Bar

In this article we will see how to create capsule shaped progress bar. By default when we create progress bar, it is in rectangular shape although we can change the shape with the help of resize method. But this will only allows to change the shape from rectangle to square. Below is representation of normal progress bar vs the capsule shaped progress bar.

In order to do so we have to change the radius of the border of both background and the bar of progress bar, this is done by changing the CSS style sheet, below is the style sheet code.

QProgressBar
{
border: solid grey;
border-radius: 15px;
color: black;
}
QProgressBar::chunk 
{
background-color: #05B8CC;
border-radius :15px;
}      

This style sheet is used which setStyleSheet method, below is the implementation.

# importing libraries

class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting background color to window
        # self.setStyleSheet("background-color : yellow")

        # 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(70)

        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)

        # setting background to color and radius
        # and bar color and bar radius
        bar.setStyleSheet("QProgressBar"
                          "{"
                          "border: solid grey;"
                          "border-radius: 15px;"
                          " color: black; "
                          "}"
                          "QProgressBar::chunk "
                          "{background-color: # 05B8CC;"
                          "border-radius :15px;"
                          "}")


App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
