PyQt5 QSpinBox – Setting display integer base

Last Updated : 06 May, 2020

In this article we will see how we can set display integer base to the spin box, a base or radix is the number of different digits or combinations of digits and letters that a system of counting uses to represent numbers. The default integer base is 10 although we can change it.

Note : Only the base of display integer base will change value base will remain 10.

In order to do this we will use spin_box.setDisplayIntegerBase method.

Syntax : spin_box.setDisplayIntegerBase(n)

Argument : It takes integer as argument

Return : 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, 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, 100, 40) 
  
        # setting display integer base 
        self.spin.setDisplayIntegerBase(2) 
  
        # adding action to the spin box 
        self.spin.valueChanged.connect(self.show_result) 
  
        # creating label show result 
        self.label = QLabel(self) 
  
        # setting geometry 
        self.label.setGeometry(100, 200, 200, 40) 
  
    # method called by spin box 
    def show_result(self): 
  
        # getting current value 
        value = self.spin.value() 
  
        # setting value of spin box to the label 
        self.label.setText("Value : " + str(value)) 
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
window.show() 
  
# start the app 
sys.exit(App.exec())
