Detailed Description

This manipulator handles the user's gestures while the layer selector is active.

The VgApplication::VgISimpleGestureManipulatorListener class allow developers to handle by themselves the gestures. The VgApplication::VgISimpleGestureManipulator is the only manipulator that accept a listener.

See VgApplication::VgISimpleGestureManipulatorListener and VgApplication::VgISimpleGestureManipulator documentation for more details.
