禁用qslider的特定键盘事件

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

class CustomSlider(QSlider):
    def keyPressEvent(self, event):
        if event.key() == Qt.Key_Left or event.key() == Qt.Key_Right:
            event.ignore()  # 忽略左右箭头键的按下事件
        else:
            super().keyPressEvent(event)  # 其他键盘事件按默认处理方式处理

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

        slider = CustomSlider(Qt.Horizontal, self)
        slider.setFocusPolicy(Qt.StrongFocus)  # 设置焦点策略，使QSlider可以接收键盘事件
        slider.setGeometry(50, 50, 200, 30)
        slider.setRange(0, 100)

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