Simulating mouse events - properly [Solved]

[Asperamanca]

For a simple automated application test, I need to simulate some mouse events. Basically, just a 'click' (down+up).

Here's the code I have come up with so far. It works quite well, but not under certain circumstances (more on that below):

@QMouseEvent* CTcmg_TestHelpers::createMouseEvent(const QWidget* const pWidget,
const QEvent::Type eventType,
const QPoint& widgetPos,
const Qt::MouseButton buttons,
const Qt::KeyboardModifiers modifiers,
Qt::MouseButton buttonCausingEvent)
{
if (pWidget == NULL)
{
return NULL;
}

QMouseEvent* pEvent = new QMouseEvent(eventType,
                                      widgetPos,
                                      pWidget->mapToGlobal(widgetPos),
                                      buttonCausingEvent,
                                      buttons,
                                      modifiers);


return pEvent;

}

void CTcmg_TestHelpers::simulateMouseClick(QWidget* const pWidget,
const QPoint& widgetPos,
const Qt::MouseButton button,
const Qt::KeyboardModifier modifiers)
{
if (pWidget == NULL)
{
return;
}

if (QApplication::instance() == NULL)
{
    return;
}

QMouseEvent* pDown = createMouseEvent(pWidget, QEvent::MouseButtonPress,
                                      widgetPos, button,
                                      modifiers, button);
QMouseEvent* pUp = createMouseEvent(pWidget, QEvent::GraphicsSceneMouseRelease,
                                    widgetPos, Qt::NoButton,
                                    modifiers, button);

(void) QApplication::instance()->sendEvent(pWidget,
                                           pDown);
QApplication::processEvents();

(void) QApplication::instance()->sendEvent(pWidget,
                                           pUp);
QApplication::processEvents();

}

It doesn't property work with QGraphicsView. It seems that the mouse event normally arrives in QGraphicsView via an event filter. For the simulated event, the event filter is not triggered.
I took a look into Qt's source code, and noticed that upon a 'real' mouse click, QApplicationPrivate::sendMouseEvent is called which does a few extra things specific to mouse events.
Sending the event via sendEvent completely bypasses these logics. QApplication::sendEvent calls QApplication::notify, and the documentation on notify implies that mouse events are correctly delivered. How can that be, if sendMouseEvent is bypassed?

Do you know a better way to simulate mouse clicks, or have any idea what I might try to make the simulated mouse events behave just like real ones?

Stupid Copy & Paste error. See GraphicsSceneMouseRelease in my code. Should be MouseReleaseEvent
