PyQt5 QSpinBox – Disconnecting it

In this article we will see how we can disconnect the spin box, disconnecting spin box means that the action which are connected to the spin box will not take place they will get disconnected. Disconnecting is exactly the opposite of connecting an action to the spin box.

In order to do this we use disconnect method

Syntax : spin_box.disconnect()

Argument : It takes no argument

Return : It returns float

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, 250, 40)

        # setting range to the spin box
        self.spin.setRange(0, 999999)

        # setting prefix to spin
        self.spin.setPrefix("Prefix ")

        # setting suffix to spin
        self.spin.setSuffix(" Suffix")

        # adding action to the spin box
        self.spin.valueChanged.connect(self.do_something)

        # disconnecting the spin box
        self.spin.disconnect()

        # creating label
        self.label = QLabel(self)

        # setting geometry to the label
        self.label.setGeometry(100, 200, 200, 70)

        # making it multi line label
        self.label.setWordWrap(True)

    # action called by spin box
    def do_something(self):

        # setting text to the label
        self.label.setText("Done Something")

# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())

Output :
