Progress Bar in PyQt5 allows us to set the range of value for the progress bar. maximum
method is used to get the maximum value of progress bar i.e upper limit of the range. This method returns the integer value, if we don’t set the range by default it is 100.
Syntax : bar.maximum()
Argument : It takes no argument
Return : It returns integer.
Code :
# 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 maximum value of progress bar to 200
bar.setMaximum( 200 )
# setting value to progress bar
bar.setValue( 100 )
# getting maximum value of progress bar
value = bar.maximum()
# creating label to print the value
label = QLabel( "maximum value = " + str (value), self )
# adjusting the size of label
label.adjustSize()
# moving the label
label.move( 200 , 200 )
# 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 ())
