Propagating event to scrollBar

[bunjee]

I'm trying to propagate an event to my QScrollbar.


/* virtual */ void ZeContactFlow::wheelEvent(QWheelEvent * event)
{
std::cout << "Hello ?\n";
if (mScrollBar)
{
QWheelEvent * newEvent = new
QWheelEvent(event->pos(), event->globalPos(), event->delta(), event->buttons(),
Qt::NoModifier, event->orientation());
QCoreApplication::postEvent(mScrollBar, newEvent);
}
}

This code has no effect. What am I doing wrong ?

So ZeContactFlow is something which doesn't inherit QAbstractScrollArea (which already does such thing)?

[bunjee]

QAbstractScrollArea instance is a child of ZeContactFlow instance.

/* virtual */ void ZeContactFlow::wheelEvent(QWheelEvent * event)
{
std::cout << "Hello ?\n";
if (mScrollBar)
{
//QWheelEvent * newEvent = new
// QWheelEvent(event->pos(), event->globalPos(), event->delta(), event->buttons(),
// Qt::NoModifier, event->orientation());
QApplication::sendEvent(mScrollBar, event);
}
else
{
event->ignore();
}
}

This implementation makes me crash
