Touch events not recognized for trackpad

[mentalmushroom]

Gestures are enabled. As I told before, I am using pinch zooming in the web browser without any problems, two, three and four finger gestures also work fine. The issue seems to occur in Qt applications only.

Maybe you need QGestureRecognizer? Or QWidget::grabGesture() or QGraphicsObject::grabGesture()?

[mentalmushroom]

Umh... but why Qt samples do not work?

[d_stranz]

Our posts are bumping into each other.

The examples may not implement gesture grabbing as mentioned above.

Thanks, i will check QGestureRecognizer.

Reading deeper into the docs, QGestureRecognizer is needed only if you are implementing custom gestures. QWidget::grabGesture() should be all you need for standard gesture support.

Try modifying one of the Qt Graphics / View examples to add grabGesture support to the view widget, see what happens. Or modify a dialog-based example to add grabGesture to the dialog class. You should then be able to tap buttons, I think. I don't have a gesture input device, so I can't try it.
