In this article we will see how we can get the notch visible property of QDial, by default the notch of QDial is disabled although we can make it visible any time with the help of setNotchesVisible
method. Notch is basically series of notches drawn around the dial to indicate the range of values available.
In order to do this we use notchesVisible
method with the QDial object
Syntax : dial.notchesVisible(True)
Argument : It takes no argument
Return : It returns bool
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 )
# 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 )
# getting notch visible property
value = dial.notchesVisible()
# setting text to the label
label.setText( "Notch Visible : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
