Image/Pixmap after scaling parcelled into 4 pieces.

Hi all, I have a board desk and using some image as background, it's saved in svg file and I render it from there to a pixmap/image. Then I scale it to size of QGraphicsView on renderEvent. But a problem is that pixmap/image is parcelled after the scaling.

There is a screenshot of the problem as attachment.

I would love to have the background in one piece not parcelled, what am I doing wrong?

Here's the renderEvent implementation:

Code:

---

void kMancalaBoard::resizeEvent ( QResizeEvent *event ) {
    qDebug("Resize event ... ");
    QSize sz(400, 300);
 
    qDebug("Width: %d, Height: %d", sz.width(), sz.height());
 
    QPixmap bg ( QSize(400, 200) );
    QPainter bgPainter ( &bg );
 
    if ( m_renderer->elementExists ( QString ( "background" ) ) ) {
        qDebug ( "Rendering" );
        m_renderer->render ( &bgPainter, QString ( "background" ), QRectF ( QPointF ( 0,0 ), sz ) );
    } else {
        qDebug ( "No background found" );
    }
 
    QSize hint = size();
    qDebug("Width: %d, Height: %d", hint.width(), hint.height());
 
    QBrush br ( bg.scaled(hint, Qt::IgnoreAspectRatio, Qt::SmoothTransformation) );
    m_scene->setBackgroundBrush ( br );
 
    QGraphicsView::resizeEvent ( event );
 
}

Wow, what's about reimp the paint method of your view and print the images directly? the painters drawPixmap method will scale the image on its own.

I'm not sure how to do that and if it would help. Problem is in setting setBackgroundBrush, if I put a image to scene as scene->addPixmap(...) image is ok. So problem is somewhere in scene painting with brush.

Added after 23 minutes:

Finally I solved that by reimplementing drawBackground of the view as you suggested.

Code:

---

void kMancalaBoard::drawBackground(QPainter *painter, const QRectF &rect) {    
    if ( m_renderer->elementExists ( QString ( "background" ) ) ) {
        qDebug ( "Rendering" );
        m_renderer->render ( painter, QString ( "background" ), rect);
    } else {
        qDebug ( "No background found" );
    }
}
