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 :
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output : 
When we tap on the button.
