In this article we will see how to set action to a push button. QPushButton is a simple button in PyQt5, when clicked by a user some associated action gets performed. For adding this button into the application, QPushButton class is used. When the button is pressed it should perform some action, in order to add action to a button we will use clicked.connect method.
Syntax : button.clicked.connect(function) Argument : It takes function as a argument. Action performed: When button will be clicked it will call the passes function.
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)
# 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 ())

Output :
pressed
