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

This includes the interaction of Zooming, Panning, Scrolling and adjusting the LevelWindow.

Member Function Documentation

◆ AdjustLevelWindow()

virtual void mitk::DisplayInteractor::AdjustLevelWindow	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Adjusts the level windows relative to mouse/pointer movement.

◆ CheckPositionEvent()

virtual bool mitk::DisplayInteractor::CheckPositionEvent ( const InteractionEvent * interactionEvent )

protectedvirtual

◆ CheckRotationPossible()

virtual bool mitk::DisplayInteractor::CheckRotationPossible ( const InteractionEvent * interactionEvent )

protectedvirtual

◆ CheckSwivelPossible()

virtual bool mitk::DisplayInteractor::CheckSwivelPossible ( const InteractionEvent * interactionEvent )

protectedvirtual

◆ Clone()

Pointer mitk::DisplayInteractor::Clone ( ) const

◆ ConfigurationChanged()

void mitk::DisplayInteractor::ConfigurationChanged ( )

overrideprotectedvirtual

Derived function. Is executed when config object is set / changed. Here it is used to read out the parameters set in the configuration file, and set the member variables accordingly.

Reimplemented from mitk::InteractionEventHandler.

◆ ConnectActionsAndFunctions()

void mitk::DisplayInteractor::ConnectActionsAndFunctions ( )

overrideprotectedvirtual

Derived function. Connects the action names used in the state machine pattern with functions implemented within this InteractionEventObserver. This is only necessary here because the events are processed by the state machine.

Reimplemented from mitk::EventStateMachine.

Reimplemented in mitk::SegmentationInteractor.

◆ DecreaseTimeStep()

virtual void mitk::DisplayInteractor::DecreaseTimeStep	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Decreases the time step in 3d+t data.

◆ EndRotation()

virtual void mitk::DisplayInteractor::EndRotation	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Ends crosshair rotation.

◆ FilterEvents()

bool mitk::DisplayInteractor::FilterEvents	(	InteractionEvent *	interactionEvent,
		DataNode *	dataNode
	)

overrideprotectedvirtual

Derived function. Is executed when config object is set / changed. Here it is used to read out the parameters set in the configuration file, and set the member variables accordingly.

Reimplemented from mitk::EventStateMachine.

◆ GetBoolProperty()

bool mitk::DisplayInteractor::GetBoolProperty	(	mitk::PropertyList::Pointer	propertyList,
		const char *	propertyName,
		bool	defaultValue
	)

protected

Method to retrieve bool-value for given property from string-property in given propertylist.

	)

protectedvirtual

Increases the time step in 3d+t data.

◆ Init()

virtual void mitk::DisplayInteractor::Init	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Initializes an interaction, saves the pointers start position for further reference.

◆ Move()

virtual void mitk::DisplayInteractor::Move	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Performs panning of the data set in the render window.

◆ New()

static Pointer mitk::DisplayInteractor::New ( )

static

◆ Notify()

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

overridevirtual

By this function the Observer gets notified 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 it already has been processed by a DataInteractor.

Implements mitk::InteractionEventObserver.

◆ Rotate()

virtual void mitk::DisplayInteractor::Rotate	(	StateMachineAction *	,
		InteractionEvent *	event
	)

protectedvirtual

◆ Scroll()

virtual void mitk::DisplayInteractor::Scroll	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Performs scrolling relative to mouse/pointer movement.

Behavior is determined by

See also: m_ScrollDirection and; m_AutoRepeat.

◆ ScrollOneDown()

virtual void mitk::DisplayInteractor::ScrollOneDown	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Scrolls one layer up.

◆ ScrollOneUp()

virtual void mitk::DisplayInteractor::ScrollOneUp	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Scrolls one layer down.

◆ SetCrosshair()

virtual void mitk::DisplayInteractor::SetCrosshair	(	StateMachineAction *	,

	)

protectedvirtual

◆ UpdateStatusbar()

virtual void mitk::DisplayInteractor::UpdateStatusbar	(	StateMachineAction *	,
		InteractionEvent *	event
	)

protectedvirtual

Updates the Statusbar information with the information about the clicked position.

◆ Zoom()

virtual void mitk::DisplayInteractor::Zoom	(	StateMachineAction *	,
		InteractionEvent *
	)

protectedvirtual

Performs zooming relative to mouse/pointer movement.

Behavior is determined by
