In this article we will see how we can get the current value of the QDoubleSpinBox. User can set any decimal value(float) to the QDoubleSpinBox with the help of mouse and keyboard, but sometimes there is a need of setting value programmatically in order to overwrite the value entered by the user, it can be set with the help of setValue method.

In order to do this we will use value method with the QDateTimeEdit object.

Syntax : d_spin.value()

Argument : It takes no argument

Return : It returns float value

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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating double spin box
        d_spin = QDoubleSpinBox(self)
  
        # setting geometry to the double spin box
        d_spin.setGeometry(100, 100, 150, 40)
  
        # value
        value = 9.99
  
        # setting current value of the double spin box
        d_spin.setValue(value)
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)
  
        # making label multi line
        label.setWordWrap(True)
  
        # getting current value of double spin box
        value = d_spin.value()
  
        # setting text to the label
        label.setText("Current Value : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
