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())
