In this article we will see how we can get slider’s value of the QDial. User can change the value with the help of mouse although we can change it programmatically with the help of setValue
method. The slider forces the value to be within the legal range i.e value should be greater than or equal to the minimum value and it should be less than or equal to the maximum limit. Changing the value also changes the slider position.
In order to do this we use value
method with the QDial object
Syntax : dial.value()
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 )
# making notch visible
dial.setNotchesVisible( True )
# value
value = 50
# setting value to the dial slider
dial.setValue(value)
# creating a label
label = QLabel( "GeeksforGeeks" , self )
# setting geometry to the label
label.setGeometry( 220 , 125 , 200 , 60 )
# making label multiline
label.setWordWrap( True )
# getting slider value
value = dial.value()
# setting text to the label
label.setText( "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 ())
