Detailed Description

Observer that manages the interaction with the display.

Inherits from mitk::InteractionEventObserver since it doesn't alter any data (only their representation), and its actions cannot be associated with a DataNode. Also inherits from EventStateMachine

mitk::ToolManager reloads the configuration of the registered mitk::DisplayInteractor objects when a tool is switched on. This configuration conflicts with most of the tools.

void niftk::DnDDisplayInteractor::ConnectActionsAndFunctions ( )

overrideprotectedvirtual

Note: We do not call the overridden function here. It assign handlers to actions that are not defined for this state machine.

niftk::DnDDisplayInteractor::mitkClassMacro	(	DnDDisplayInteractor	,
		DisplayInteractor
	)

void niftk::DnDDisplayInteractor::Notify	(	mitk::InteractionEvent *	interactionEvent,
		bool	isHandled
	)

overridevirtual

By this function the Observer gets notifier about new events. Here it is adapted to pass the events to the state machine in order to use its infrastructure. It also checks if event is to be accepted when i already has been processed by a DataInteractor.

bool niftk::DnDDisplayInteractor::Pan	(	mitk::StateMachineAction *	action,
		mitk::InteractionEvent *	interactionEvent
	)

protectedvirtual

bool niftk::DnDDisplayInteractor::SelectNextSlice	(	mitk::StateMachineAction *	action,
		mitk::InteractionEvent *	interactionEvent
	)

protectedvirtual

Selects the next slice. The slices are ordered in the following way: axial: inferior to superior sagittal: right to left coronal: anterior to posterior.

Note: We do not implement scrolling for the 3D window.

Note: This does not work if the slice are locked. See: SingleViewerWidget::SetNavigationControllerEventListening(bool) and QmitkMultiWindowWidget::SetWidgetPlanesLocked(bool)

bool niftk::DnDDisplayInteractor::SelectNextTimeStep	(	mitk::StateMachineAction *	action,
		mitk::InteractionEvent *	interactionEvent
	)

protectedvirtual

Selects the next time step.

bool niftk::DnDDisplayInteractor::SelectPosition	(	mitk::StateMachineAction *	action,
		mitk::InteractionEvent *	interactionEvent
	)

protectedvirtual

Note: We do not re-implement position selection for the 3D window.

bool niftk::DnDDisplayInteractor::SelectPreviousSlice	(	mitk::StateMachineAction *	action,
		mitk::InteractionEvent *	interactionEvent
	)

protectedvirtual

Selects the previous slice. The slices are ordered in the following way: axial: inferior to superior sagittal: right to left coronal: anterior to posterior.

Note: We do not implement scrolling for the 3D window.

Note: This does not work if the slice are locked. See: SingleViewerWidget::SetNavigationControllerEventListening(bool) and QmitkMultiWindowWidget::SetWidgetPlanesLocked(bool)

protectedvirtual

Starts scrolling through slices in a loop backwards.

protectedvirtual

Like Superclass::Init, but blocks the update and selects the focused window. It also changes the selected position to the middle of the focused voxel.

Note that the zoom focus must always be the selected position, i.e. the position at the cursor (crosshair).
