One little side note. Putting enumerations into classes can introduce a 
dependency. Using them in mocks is much harder because there are easily 
hard linking dependencies on the library and not only a header file with 
the enumerations.

So what about moving them out of the class into an extra header file?

Like

TouchPoint::Pressed -> Touch::Pressed

enum class  Touch : int {
   Pressed,
   ...
};

They than could be forward declared too.
