Android gestures

[MartinD]

I have a Qt 5.11.2 app running on Lenovo Tab E10 tablet. In a custom widget, I would like to receive gestures.

I called this in constructor of the widget:

setAttribute( Qt::WA_AcceptTouchEvents );
grabGesture( Qt::PinchGesture );

I then implemented method in my widget:

bool QCustomPlot::event( QEvent *event ){
    qDebug() << "QCustomPlot::event" << event->type();
>

However, for two fingers pinch gesture I only receive QEvent::Type(MouseButtonPress), multiple QEvent::Type(MouseMove) and QEvent::Type(MouseButtonRelease) events.

I would be able to build pinch gesture from mouse events but I never receive any event for second finger touching the screen.

So, how to enable pinch gesture on my tablet? If it is not possible, how can I build pinch gesture from mouse events?

I've never read anyone succeed in this and if you don't get events for the other finger, it might be impossible.
