PyQt5 QDial – Setting Range of Dial
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("zambiatek", 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()) |
