PyQt5 – Skin to Bar of Progress Bar

In this article we will see how to set the skin to the bar of progress bar. Skin is basically a background image but it adjust it self to the size of bar of progress bar. Below is the representation of bar of progress bar with background image and bar of progress bar with skin.

In order to do this we have to change the CSS style sheet code of bar of progress bar which is used with the setStyleSheet method, below is the style sheet code.

QProgressBar
{
border :1px solid black;
}
QProgressBar::chunk
{
border-image : url(skin.png);
}

Below is the implementation.

# importing libraries
from PyQt5.QtWidgets import *

from PyQt5.QtGui import *

import sys


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
        value = 70
        bar.setValue(value)

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

        # setting skin to bar to progress bar
        bar.setStyleSheet("QProgressBar "
                          "{"
                          "border : 1px solid black;"
                          "}"
                          "QProgressBar::chunk"
                          "{"
                          "border-image : url(skin.png);"
                          "}"
                          )


App = QApplication(sys.argv)

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

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

Output :
