In this article we will see how we can block the signals of the button, blocking signals means stopping the button to do this assigned task. It is used to make a button deactive. In order to do this we will use blockSignals method which belongs to QObject class.

Syntax : button.blockSignals(True) Argument : It takes bool as argument. Action performed: It blocks the signal of button.

Code : 


# importing libraries
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
    def __init__(self):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
    # method for widgets
    def UiComponents(self):
        # creating a push button
        button = QPushButton("CLICK", self)
        # setting geometry of button
        button.setGeometry(200, 150, 100, 30)
        # adding action to a button
        # blocking signals of the button
    # action method
    def clickme(self):
        # printing pressed
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app

Output : pyqt-disable-button When this button will be clicked nothing will happen.
