PyQt5 – Test Tube Progress Bar

In this article we will see how can we create test tube shaped progress bar. Basically test tube shape progress bar is vertical progress bar with rounded edge at the bottom. Below is the representation of test tube progress bar.

In order to do this we have to do the following – 1. Changing the orientation of progress bar from horizontal to vertical 2. Creating round corners to the progress bar at the bottom 3. Creating round corner to bar of progress bar at bottom.

In order to create round bottom to both progress bar and bar of progress bar, below is style sheet code.

QProgressBar
{
border: 1px solid black;
border-bottom-right-radius: 15px;
border-bottom-left-radius: 15px;
}
QProgressBar::chunk 
{
border-bottom-right-radius: 14px;
border-bottom-left-radius: 14px;
background : lightgreen;
}      

Below is the implementation. 

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(250, 90, 30, 200)

        # set value to progress bar
        bar.setValue(40)

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

        # setting orientation to vertical
        bar.setOrientation(QtCore.Qt.Vertical)

        # setting rounded border at the bottom
        # setting rounded border to the bottom of bar of progress bar
        # and color
        bar.setStyleSheet("QProgressBar"
                          "{"
                          "border : 1px solid black;"
                          "border-bottom-right-radius: 15px;"
                          "border-bottom-left-radius: 15px;"
                          "}"
                          "QProgressBar::chunk"
                          "{"

                          "border-bottom-right-radius: 14px;"
                          "border-bottom-left-radius: 14px;"
                          "background : lightgreen"
                          "}"
                          )


# create pyqt5 app
App = QApplication(sys.argv)

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

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

Output :
