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 :
Python3
# 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 ())
