class MyWindow(QMainWindow):
    def __init__(self):
        super().__init__()

self.setWindowTitle("Signal Example")
self.setGeometry(100, 100, 200, 100)

button = QPushButton("Click me", self)

def handle_button_click():
    print("Button clicked")

button.clicked.connect(handle_button_click)

self.show()

from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton

class MyWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Signal Example")
        self.setGeometry(100, 100, 200, 100)
        
        button = QPushButton("Click me", self)
        button.clicked.connect(self.handle_button_click)
        
        self.show()

    def handle_button_click(self):
        print("Button clicked")

if __name__ == '__main__':
    app = QApplication([])
    window = MyWindow()
    app.exec_()
