In this article we will see how to display the decimal values in Progress Bar. We can set the value in progress bar using setValue
method but it takes integer as argument. If we try to pass float or double value, it will automatically convert them into integer.
In order to do this we have to do the following :
- Change the maximum range value of progress bar, by default it is from 0 to 100. If we want to show 1 decimal value set it to 100*n here ‘n’ will be 10, if we want to show 2 decimal values set it to 100*n here n will be 100 and so on.
- Set value to progress bar by multiplying it by ‘n’.
- Use format method to display the decimal value.
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 , 150 , 200 , 30 )
# setting value of n for 2 decimal values
n = 100
# setting maximum value for 2 decimal points
bar.setMaximum( 100 * n)
# value in percentage
value = 75.55
# setting the value by multiplying it to 100
bar.setValue(value * n)
# displaying the decimal value
bar.setFormat( "%.02f %%" % value)
# setting alignment to centre
bar.setAlignment(Qt.AlignCenter)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
