如何检测PyQt5中的冲突

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

class EventFilter(QObject):
    def eventFilter(self, watched, event):
        if event.type() == Qt.MouseButtonPress:
            print(f"Mouse pressed on {watched}")
        return super().eventFilter(watched, event)

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.button = QPushButton("Click me", self)
        self.button.installEventFilter(EventFilter(self))
        self.button.clicked.connect(self.on_button_click)

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

app = QApplication([])
window = MainWindow()
window.show()
app.exec_()

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

class TestButton(unittest.TestCase):
    def setUp(self):
        self.app = QApplication([])
        self.button = QPushButton("Test Button")

    def test_button_click(self):
        self.button.clicked.connect(lambda: setattr(self.button, 'clicked', True))
        self.button.click()
        self.assertTrue(hasattr(self.button, 'clicked'))

if __name__ == '__main__':
    unittest.main()
