Member Function Documentation

void XnVClickableVirtualPlane::Click ( XnUInt32  ,
const XnPoint3D &  ptPosition 

Invoke the click event

[in]ptPositionThe position of the click
void XnVClickableVirtualPlane::FreezeCoordinates ( XnUInt32  nID,
const XnPoint3D &  ptPosition 

Freeze the coordinates - a click is starting.

[in]nIDThe ID of the point to freeze
[in]ptPositionThe coordinates to send from now on
XnBool XnVClickableVirtualPlane::IsFrozen ( XnUInt32  nID) const

Check if a specific point is frozen

[in]nIDThe ID the point
TRUE if the point is frozen, FALSE o/w
void XnVClickableVirtualPlane::OnPointCreate ( const XnVHandPointContext pContext) [virtual]

Called when a point is created.

[in]pContextThe hand context of the newly created point

Reimplemented from XnVVirtualCoordinates.

void XnVClickableVirtualPlane::OnPointDestroy ( XnUInt32  nID) [virtual]

Called when a point is destroyed.

[in]nIDthe ID of the destroyed point

Reimplemented from XnVVirtualCoordinates.

XnCallbackHandle XnVClickableVirtualPlane::RegisterClick ( void *  cxt,
ClickCB  CB 

Register for the click event

[in]cxtUser's context
[in]CBThe Callback to call when the event is invoked.
A handle, to allow unregistration.
void XnVClickableVirtualPlane::UnfreezeCoordinates ( XnUInt32  nID)

Unfreeze the coordinates - a click is no longer searched.

[in]nIDThe ID of the point to unfreeze.
void XnVClickableVirtualPlane::UnregisterClick ( XnCallbackHandle  hCB)

Unregister from the click event

[in]hCBThe handle provided on registration.
void XnVClickableVirtualPlane::UpdateVirtualPoint ( XnVVirtualCoordinatesInternal *  pVC,
const XnVHandPointContext pContext,
XnVHandPointContext pLocalContext 
) [protected, virtual]

Reimplemented from XnVVirtualCoordinates.
