主要就是这个类QGraphicsDropShadowEffect 具体可以看它

HightlightText::HightlightText(QWidget *parent)
    : QMainWindow(parent)
{
    ui.setupUi(this);

    auto *shadow_effect = new QGraphicsDropShadowEffect(this);

    shadow_effect->setOffset(0, 0);

    shadow_effect->setColor(Qt::gray);

    shadow_effect->setBlurRadius(20);

    setGraphicsEffect(shadow_effect);


    setWindowFlag(Qt::FramelessWindowHint);
    setAttribute(Qt::WA_TranslucentBackground);

    QFont font;
    font.setFamily("微软雅黑");
    font.setPixelSize(50);
    font.setBold(true);
    setFont(font);
}

void HightlightText::paintEvent(QPaintEvent *event)
{
    QPainter p(this);
    p.setPen(Qt::red);
    p.drawText(rect(), Qt::AlignCenter, tr("Qt\nProject"));
}
