In this article we will see how we can set range to the QDial. Range means both upper and lower bound at the same time so that user can assign any value which don’t lies between the range. We can set lower and upper bound to the QDial with the help of setMinimum
and setMinimum
method respectively.
In order to do this we use setMaximum
method with the QDial object
Syntax : dial.setRange(min, max)
Argument : It takes two integer as argument
Return : It returns None
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 , 500 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for components
def UiComponents( self ):
# creating QDial object
dial = QDial( self )
# setting geometry to the dial
dial.setGeometry( 100 , 100 , 100 , 100 )
# setting range
dial.setRange( 100 , 120 )
# making notch visible
dial.setNotchesVisible( True )
# creating a label
label = QLabel( "GeeksforGeeks" , self )
# setting geometry to the label
label.setGeometry( 220 , 125 , 200 , 60 )
# making label multiline
label.setWordWrap( True )
# adding action to the dial
dial.valueChanged.connect( lambda : label.setText( "Value = " + str (dial.value())))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
