In this article we will see how we can make a spin box which can’t take input from the keyboard, when we create a spin box there are basically two ways to change the value of the spin box one is by using arrow buttons or other way is using key board. Stopping key board input of spin box means user will not be able to enter a value in spin box using keyboard although user can make increment or decrement using arrow buttons.
In order to stop key board input we use setReadOnly method with the line edit object Syntax : line_edit.setReadOnly(True) Argument : It takes bool as argument Action performed : It will make the line edit object read only
In order to do this we have to do the following : 1. Create a main window 2. Create a spin box 3. Get the line edit object from the spin box 4. Make the line edit part read only Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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, 250, 40) # setting prefix to spin self.spin.setPrefix("Prefix ") # setting suffix to spin self.spin.setSuffix(" Suffix") # getting the line edit line = self.spin.lineEdit() # making the line edit part read only line.setReadOnly(True)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
