如何在pyqt5中创建这样的按钮？

from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
from PyQt5.QtCore import Qt

app = QApplication([])

window = QMainWindow()
window.setWindowTitle("按钮示例")
window.setGeometry(100, 100, 300, 200)  # 设置窗口位置和大小

button = QPushButton("点击我", window)
button.setGeometry(50, 50, 200, 100)  # 设置按钮位置和大小
button.setStyleSheet("background-color: blue; color: white; font-size: 20px;")

def on_button_clicked():
    print("按钮被点击了！")

button.clicked.connect(on_button_clicked)

window.show()

app.exec_()
