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 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
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
def __init__( self ):
super ().__init__()
self .setWindowTitle("Python ")
self .setGeometry( 100 , 100 , 600 , 400 )
self .UiComponents()
self .show()
def UiComponents( self ):
button = QPushButton("CLICK", self )
button.setGeometry( 200 , 150 , 100 , 30 )
button.clicked.connect( self .clickme)
button.blockSignals( True )
def clickme( self ):
print ("pressed")
App = QApplication(sys.argv)
window = Window()
sys.exit(App. exec ())
|
Output : When this button will be clicked nothing will happen.
