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.

virtual void FloorSelectorManipulator::onSimpleDrag ( const VgEngine::VgGestureState  pState, const unsigned int  pNbTouch, const float  pAverageXOffset, const float  pAverageYOffset  )

virtual

This override displaces the layers when the user performs a vertical drag.

It triggers the layer change if the drag is above a threshold.

virtual void FloorSelectorManipulator::onSimplePinch ( const VgEngine::VgGestureState  pState, const float  pSpan, const float  pVelocity  )

virtual

This override triggers the selection of the centered floor if the pinch gesture is a quick zoom-in.
