One of the implementation is made by Zeno Albisser (CCed), we can tell you whether it is available from a public repository, or when it can be made available. However I would like to stress that those are only experiments, and there are no decision which qml api will end up in Qt.

For Natty with GEIS 2.0 we are going to map those gestures to Qt gestures, however that work hasn't started yet.

Thank you for the clear answer Denis. Are the experiments to translate
GEIS 1.0 gestures into Qt gestures public? When do you think the work on
adapting these to GEIS 2.0 will start?
Correct me if I am wrong but if the gestures are translated into Qt
gestures, does that mean that using the experimental QML APIs one could
receive gestures from GEIS?
