The gtk:gesture-pan object is a gtk:gesture implementation able to recognize pan gestures, those are drags that are locked to happen along one axis. The axis that a gtk:gesture-pan object handles is defined at construct time, and can be changed through the gtk:gesture-pan-orientation function.

When the gesture starts to be recognized, The gtk:gesture-pan object will attempt to determine as early as possible whether the sequence is moving in the expected direction, and denying the sequence if this does not happen.

Once a panning gesture along the expected axis is recognized, the "pan" signal will be emitted as input events are received, containing the offset in the given axis.
