qpainter画一个闪电

好的，我可以使用 QPainter 来画一个闪电形状。下面是画闪电的示例代码：

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget
from PyQt5.QtGui import QPainter, QColor, QPen
from PyQt5.QtCore import Qt


class LightningWidget(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('闪电')
        self.setGeometry(100, 100, 400, 400)

    def paintEvent(self, event):
        painter = QPainter(self)
        painter.setRenderHint(QPainter.Antialiasing)

        pen = QPen()
        pen.setWidth(3)
        pen.setColor(Qt.yellow)
        painter.setPen(pen)

        # 闪电形状的路径
        path = QPainterPath()
        path.moveTo(200, 100)
        path.lineTo(230, 200)
        path.lineTo(180, 200)
        path.lineTo(210, 300)
        path.lineTo(170, 300)
        path.lineTo(200, 400)

        painter.drawPath(path)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = QMainWindow()
    widget = LightningWidget()
    window.setCentralWidget(widget)
    window.show()
    sys.exit(app.exec_())

运行上述代码后，会显示一个窗口，并在窗口中绘制出一个闪电形状。你可以根据需要调整绘制的位置和颜色。
