PyQt5 QDial – Making Notch Visible

0 0 1 minute read

In this article we will see how we can make the notch of QDial visible, by default the notch of QDial is disabled although we can make it visible any time. Notch is basically a series of notches drawn around the dial to indicate the range of values available.

In order to do this we use setNotchesVisible method with the QDial object

Syntax : dial.setNotchesVisible(True)

Argument : It takes bool 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) 
  
        # making notch visible 
        dial.setNotchesVisible(True) 
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
