In this article we will see how we can make spin box disabled according to the user, disabled spin box box is basically spin box which can’t be edited i.e which get disabled. Below is the representation of how disabled spin box looks like.


In order to do so we use setDisabled method.

Syntax : spin_box.setDisabled(bool)

Argument : It takes bool as argument

Return : It returns None

Implementation steps :
1. Create a spin box
2. Create a push button
3. Add action to the push button
4. Inside the action make the spin box disabled

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, 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 prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # setting range to spin
        self.spin.setRange(0, 99999)
  
        # creating push button
        button = QPushButton("Press", self)
  
        # setting button geometry
        button.setGeometry(100, 160, 100, 40)
  
        # adding action to the push button
        button.clicked.connect(self.push_method)
  
    # method called by push button
    def push_method(self):
  
        # making spin box disabled
        self.spin.setDisabled(True)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
