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.
# 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 ())
