    有没有大佬能提供一个鼠标穿透的程序的思路，Python，c, QT都可以，我在deepin和uos用了各种办法尝试做一个透明无边框，鼠标穿透效果的窗口，但都失败了，窗口显示都没有问题，鼠标穿透不行。

    QWidget::setAttribute(Qt::WA_TransparentForMouseEvents, true) 试试看？

    P.S. 我记得在 Deepin 20 很早的版本上，一个无边框的 QWidget 如果设置背景色为全透明，默认就是鼠标穿透的效果......

    widget.resize(400, 300);
    widget.show();

    return app.exec();

    设置都没问题，但是就是没效果
