Paint with background color and transparent pixmap in foreground

helgur

I'm using QPainters fillrect method to paint a rect on a scene (second conditional statement):


void TheSquare::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)  {
    QRectF rec = boundingRect();

    Q_UNUSED(widget);
    Q_UNUSED(option);

    QBrush brush;
    QColor bordercolor;
    QPen borderpen;

    if (this->isSelected()) {
        // works as planned
        brush = QBrush(Qt::yellow);
        bordercolor = QColor(Qt::black);
        borderpen = QPen(bordercolor,1);
        painter->setBrush(Qt::Dense3Pattern);
    } else if (doOperation || hasChanged) {
        // does not work, here's the problem
        brush = QBrush(color,pix);
        bordercolor = QColor(Qt::black);
        borderpen = QPen(bordercolor,1);
    } else if (!hasChanged) {
        // works as planned
        brush = QBrush(Qt::white);
        bordercolor = QColor(Qt::black);
        borderpen = QPen(bordercolor,1);
    }

    painter->setPen(borderpen);
    painter->fillRect(rec, brush);
    painter->drawRect(rec);
}

Problem is that it is only painting the texture pixmap, not the background color. How would I proceed to fill the rect with a background color and the pixmap in the foreground?

The solution was pretty easy, but I overlooked it:

QBrush bgBrush,fgBrush;

bgBrush = QBrush(color);
fgBrush = QBrush(pixMap);

painter->setPen(borderpen);
painter->fillRect(rec, bgBrush);
painter->fillRect(rec, fgBrush);
painter->drawRect(rec);

Just a brainfart from my side, nothing to see here. Move on!
