RippleButton类可以在一个Python脚本中工作，但不能在处理屏幕时工作

from PyQt5.QtWidgets import QApplication, QPushButton
from PyQt5.QtCore import Qt, QPropertyAnimation, QPoint
from PyQt5.QtGui import QColor

class RippleButton(QPushButton):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.setMouseTracking(True)

    def mousePressEvent(self, event):
        if event.button() == Qt.LeftButton:
            self.start_ripple(event.pos())
        super().mousePressEvent(event)

    def start_ripple(self, pos):
        ripple = RippleAnimation(self, pos)
        ripple.start()

class RippleAnimation(QPropertyAnimation):
    def __init__(self, button, start_pos):
        super().__init__(button, b"geometry")
        self.setDuration(1000)
        self.setStartValue(QRect(start_pos, QSize()))
        self.setEndValue(QRect(start_pos, QSize(button.width(), button.height())))
        self.valueChanged.connect(self.update_ripple)

    def update_ripple(self, rect):
        # 更新波纹效果的逻辑
        pass

app = QApplication([])
button = RippleButton("Click Me")
button.show()
app.exec_()
