In this article we will see how we can make the spin box read only, read only means that user will not be able to change the value of it. It is similar to making a spin box disabled but when spin box is disabled its other properties are turned off as well but in read only no one can edit the text. In order to do this we use setReadOnly method with the spin box object.
Syntax : spin_box.setReadOnly(True) Argument : It takes bool as argument Return : It returns None
Below is the implementation
Python3
# 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 , 600 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for widgets
def UiComponents( self ):
# creating spin box
self .spin = QSpinBox( self )
# setting geometry to spin box
self .spin.setGeometry( 100 , 100 , 250 , 40 )
# setting range to the spin box
self .spin.setRange( 1 , 999999 )
# setting prefix to spin
self .spin.setPrefix("PREFIX ")
# setting suffix to spin
self .spin.setSuffix(" SUFFIX")
# making spin box read only
self .spin.setReadOnly( True )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
