void VgMyStackedLayerAndCameraHandlerOldWithPinch::gotoLayer	(	const std::string &	pLayerName,
		bool	pIsAnimated = true
	)		[virtual]

Focus a specific layer.

Parameters:

pLayerName	Layer that will be focused. keeps current mode.
pIsAnimated	If true then animates the transition, otherwise does not.

Implements VgMyLayerAndCameraHandler.

void VgMyStackedLayerAndCameraHandlerOldWithPinch::gotoLayer	(	const unsigned int	pLayerIndex,
		bool	pIsAnimated = true
	)		[virtual]

Focus a specific layer.

Parameters:

pLayerName	Layer index which is associated with the returned list given by VgLayerManager::getLayers(). keeps current mode.
pIsAnimated	If true then animates the transition, otherwise does not.

Implements VgMyLayerAndCameraHandler.

void VgMyStackedLayerAndCameraHandlerOldWithPinch::gotoLookAtPosition	(	const VgEngine::VgPosition &	pPosition,
		const std::string &	pLayerName,
		bool	pIsAnimated = true
	)		[virtual]

Moves the camera so that it is focused on a given position.

The camera's view, heading, pitch are always conserved. The altitude of pPosition is automatically set to zero.

If the pLayerName isn't the currently focused layer, then before any camera movement is invoked, pLayerName becomes the focused layer.

Note:

If the stack is in global view, the camera will not change.

Parameters:

pPosition	The position to focus on.
pLayerName	The name of the layer associated with the position.
pIsAnimated	If true then animates the transition, otherwise does not.

Implements VgMyLayerAndCameraHandler.

Moves the camera to a specific view point.

If the pLayerName isn't the currently focused layer, then before any camera movement is invoked, pLayerName becomes the focused layer.

Note:

If the stack is in global view, the camera will not change.

Parameters:

pViewPoint	The view point to associate with the camera
pLayerName	The layer which should be given the focus.
pIsAnimated	If true then animates the transition, otherwise does not.

Implements VgMyLayerAndCameraHandler.

Parameters:

pParam

The parameter to be set. Please see the VgMyConfigurableParam type to gain an understanding of what each configurable parameter is responsible for.

Note:

If parameters are changed via this method, then it is necessary to call refreshStackView() in order for the global stack view to be updated to reflect the new values.

Implements VgMyLayerAndCameraHandler.

void VgMyStackedLayerAndCameraHandlerOldWithPinch::switchToGlobalView

(

bool

pIsAnimated = true )

[virtual]

Switches from the detailledView to the global view.

Do nothing if already in global view.

Parameters:
