Documentation for Gestures Does Not Specify Supported Devices Nor Platform Gestures

I would have expected the documentation for gestures to mention what devices are supported and how to do the gestures on those platforms. I could not find this documentation anywhere.

I started looking here:

http://doc.qt.nokia.com/4.6/gestures-overview.html

Here's a partial list of what's supported or not, based on my testing using the "imagegestures" example included in Qt:

Windows 7:
Mouse: Gestures not supported
Mac:
Mouse: Gestures not supported
Multi-touch trackpad:
QSwipeGesture: Need to use 3 fingers to swipe (platform standard), not the 1 finger as gesture picture here suggests: http://doc.qt.nokia.com/4.6/qswipegesture.html#details
QPinchGesture: supported as described
QPanGesture: does not work with 1 finger as gesture picture suggests – unknown if it works or not: http://doc.qt.nokia.com/4.6/qpangesture.html#details
Linux:
Mouse: Gestures not supported
Single-touch touchscreen: Gestures not supported

Since the majority of input devices are not supported and the documentation does not mention which devices are supported, I believe the documentation should be revised and have some sort of table like the above – preferably fleshed out by knowledgeable developers rather than me. Thanks for your help!
