In this article we will see how we can get the lower bound of QDial. Lower bound means the lowest value QDial can handle by default the minimum value is 0 although we can change it any time with the help of setMinimum method. With the lower bound we can make sure the number below the lower bound can be assigned. Setting lower bound will not affect the movement of the Qdial it will still able to move 360 degree.
In order to do this we use minimum method with the QDial object
Syntax : dial.minimum()
Argument : It takes no argument
Return : It returns integer
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 minimum value to the dial dial.setMinimum(50) # 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) # adding action to the dial dial.valueChanged.connect(lambda: label.setText("Value = " + str(dial.value()))) # getting minimum value value = dial.minimum() # setting text to the label label.setText("Minimum Value : " + 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 :
