Scrolling a QTableView via touch

[Andy314]

1. Problem:
   For a QTableView I have configured VerticalScrollMode = ScrollPerItem.
   Therefore it should be possible to scroll the TableView via 2FingerTouch
   This work not correct. It scrolls round about 10 Items by a move of round about 1 table row-height.

2. Problem:
   I dont like the 2 Finger touchgestures for scroll, so I found the following code:
   QScroller::grabGesture(ui->TableView, QScroller::LeftMouseButtonGesture);
   This enables indeed the touch scrolling feature with on finger.
   This does not work a well. I scrolls much more faster, therefore I think here I scrollPerPixel is used.

How can I get a "normal" scrolling via touch? Distance of finger move should amount of scrolling.

try playing around with the QScrollerProperties:

QScroller::grabGesture(ui->TableView, QScroller::LeftMouseButtonGesture);

QScroller* scroller = QScroller::scroller( ui->TableView );
QScrollerProperties props = scroller ->scrollerProperties();
props.setScrollMetric( QScrollerProperties::MaximumVelocity, QVariant::fromValue<qreal>(0.5) );
// ... take a look at the other properties also
scroller->setScrollerProperties( props );
