PyQt5 QDoubleSpinBox – Checking if it is editable or not

  • Last Updated : 28 Jul, 2020
Geek Week

In this article we will see how we can if the QDoubleSpinBox is non editable or editable. By default when we create a double spin box it is editable i.e its value can be changed by user any time, although by making it non editable with the help of setReadOnly method, then its value can’t be changed, user can only view the value.

In order to do this we will use isReadOnly method with the double spin box object.

Syntax : dd_spin.isReadOnly()

Argument : It takes no argument

Return : It returns bool



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)
  
        # setting decimal precision
        d_spin.setDecimals(1)
  
        # step type
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType
  
        # adaptive step type
        d_spin.setStepType(step_type)
  
        # making it non editable
        d_spin.setReadOnly(True)
  
        # 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)
  
        # checking if it is non editable
        value = d_spin.isReadOnly()
  
        # setting text to the label
        label.setText("Non Editable ? : " + str(value))
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
