[Interest] SpaceNavigator 3D input device support

[Christian Gagneraud]

Hi there,

Is anyone aware of a Qt based lib that would provide support for devices 
like the SpaceNavigator? [1]

I'm aware of at least one Qt based app (FreeCAD [2]) that works on 
Linux, OS X and Windows and which has support for this device. I had a 
look at the source code, it is not that complicated [3], but there's lot 
of boilerplate for multi-platform support.

So i just wondered if someone out there has a nice Qt lib that is easy 
to integrate into existing projects or even better a Qt input plugin?

Thx,
Chris
