PyQt5 – Block signals of push button
In this article we will see how we can block the signals of the button, blocking signals means stopping the button to do his 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): 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 a push button button = QPushButton("CLICK", self) # setting geometry of button button.setGeometry(200, 150, 100, 30) # adding action to a button button.clicked.connect(self.clickme) # blocking signals of the button button.blockSignals(True) # action method def clickme(self): # printing pressed print("pressed") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
