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("neveropen", 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()) |
Output :
