Qt 仿FANUC 刀库功能

看到FANUC的这个刀库功能，感觉很有意思，照着用Qt写了一个:

如你所见，支持任意大小缩放，支持旋转动画。主要函数如下：

void VToolMag::drawRing(QPainter &painter, int ringWidth, int marin)
{
    painter.save();
    painter.setPen(Qt::NoPen);
    painter.setBrush(Qt::black);
    QPainterPath p;
    QRect rect(-100 + marin, -100 + marin, 200 - marin * 2, 200 - marin * 2);
    p.arcMoveTo(rect, 0);
    p.arcTo(rect, 0, 360);
    rect.adjust(ringWidth, ringWidth, -ringWidth, -ringWidth);
    p.arcMoveTo(rect, 0);
    p.arcTo(rect, 0, 360);
    painter.drawPath(p);
    painter.restore();
}

void VToolMag::drawToolPair(QPainter &painter, double radius, double bigRadius)
{
    painter.save();
    QFont font(this->font());
    font.setPixelSize(radius * 2 - 2);
    painter.setFont(font);
    painter.setPen(QColor("#4ECCA3"));

    double dAngle = 360.0 / m_toolPairNum;
    for (int i = 0; i < m_toolPairNum; ++i)
    {
        painter.save();
        double x = bigRadius * std::cos(qDegreesToRadians(-dAngle * i + m_curRotate));
        double y = bigRadius * std::sin(qDegreesToRadians(-dAngle * i + m_curRotate));

        painter.drawText(QRectF(x - radius, y - radius, radius * 2, radius * 2),
                         QString().sprintf("%02d", i + 1), QTextOption(Qt::AlignCenter));
        painter.restore();
    }
    painter.restore();
}

void VToolMag::paintEvent(QPaintEvent *event)
{
    Q_UNUSED(event)
    int width = this->width();
    int height = this->height();
    int side = qMin(width, height);
    QPainter painter(this);
    painter.fillRect(this->rect(), QColor(57, 62, 70));
    painter.setRenderHint(QPainter::Antialiasing);
    painter.scale(side / 230.0, side / 230.0);
    painter.translate(100, 100);

    int marin = 2;
    int ringWidth = 40;
    drawRing(painter, ringWidth, marin);

    double span = 2.0;
    double radius = ringWidth / 4.0 - span;
    double bigRadius = 100 - radius - marin - span;
    drawTool(painter, radius, bigRadius);
    bigRadius -= (radius * 2 + span);
    drawToolPair(painter, radius, bigRadius);

    drawInstallToolPos(painter);
    drawSpdl(painter);

    drawComment(painter, radius);
}
