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()) |
Output :
