Custom mouseMoveEvent - how to keep default behavior

[ademmler]

Hi,

I have overwritten mouseMoveEvent() in my QGraphicsView. So far it does what I need.
But now the default behavior for "dragMode = ScrollHandDrag" is broken. Means I can't move the "visible section" does not move any longer,
when I try to click and drag the scene around.

How do I keep the default behavior also active / available. Aka how to reimplement the defaults.

void QEnhancedGraphicsView::mouseMoveEvent(QMouseEvent *event)
{
    //I do my stuff here (Getting coordinates)
    QString text;
    text = QString("%1 X %2").arg(event->pos().x()).arg(event->pos().y());
    QToolTip::showText(this->mapToGlobal(QPoint(event->pos().x(), event->pos().y())), text);
    emit signalSendCoordinates(event->pos());

}

As @JonB said, add

QGraphicsView::mouseMoveEvent(event);

below or above your code.

@ademmler
Do you mean calling the base implementation before/after your stuff?

Hi Gentlemen,

thank you - works like a charm! To whom I should give the credit now?
