In this article we will see how we can get the current value of the spin box. By default its value is 0 although user can change it any time and programmatically we use setValue method to change its value.

In order to get the value of spin box we use value method

Syntax : spin.value()

Argument : It takes no argument

Return : It returns integer i.e current value

Implementation steps –

1. Create a spin box widget
2. Create a label to show current value
3. Add action to the spin box
4. Inside the action get the current value with the help of value method
5. Show this value with the help of label.

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)
  
        # 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())
