Member variables should be prefixed with a lowercase m.

Also, some of the names are too generic, e.g. timestamp in the context of DocumentView is not descriptive enough.

That said, I wonder why all of those variables are really necessary. Is there no Qt mechanism to differentiate between different gesture and to get at timestamps or positions of gestures?

I did not review event, gestureEvent and the corresponding functions in ThumbnailView in detail yet, but some general comments:

  • For a general event function, there is way too much gesture code in there. This should perhaps be split up a bit (see Qt's gestures example, 9d90a08ef5e2, or 618072f8a2ea).
  • Why is there so much code? Is there no support in Qt to detect that kind of gestures, e.g. any of QGesture's children like QTapAndHoldGesture, QPanGesture etc.? Would it make sense to subclass QGestureRecognizer if not?
  • Some parts could use more comments to make the purpose of some of the code easier to understand.
