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
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)
def clickme( self ):
print ("pressed")
App = QApplication(sys.argv)
window = Window()
sys.exit(App. exec ())
|
Output : When we tap on the button.
