Macbook trackpad & singer finger events

[ixSci]

Hi there!

I'm trying to get event when user touch the trackpad with single finger but have no success. I receive events only for 2 more fingers.
I've set Qt::WA_AcceptTouchEvents and Qt::WA_TouchPadAcceptSingleTouchEvents to the main window.
What else should I do to start receive those events?

Thanks!

On the words you are doing all in the right way. Can you show snippet of your code?

@MainWindow::MainWindow(QWidget *parent)
{
...
qApp->installEventFilter(this);
setAttribute(Qt::WA_AcceptTouchEvents);
setAttribute(Qt::WA_TouchPadAcceptSingleTouchEvents);
}
bool MainWindow::eventFilter(QObject *, QEvent * pEvent)
{
switch(pEvent->type())
{
case QEvent::TouchBegin:
qDebug("BEGIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
break;
case QEvent::TouchUpdate:
qDebug("UPDATE!!!!!!!!!!!!!!!!!!!!!!!!!!");
break;
case QEvent::TouchEnd:
qDebug("END!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
break;
};
return false;
}@
It prints nothing for 1 finger.

It seems I've found the issue: widgets which are lied on top of my window receive touch events and since they doesn't have Qt::WA_TouchPadAcceptSingleTouchEvents, just ignore it.
Is there a better solution then just set that flag to all descendants recursively?
