Detailed Description

nnInteractive interactor for placing individual points.

Points are managed in up to two PointSet data nodes, separated by prompt type. Point placement is restricted to the bounds of the reference image.

Interaction is handled through the PointSetDataInteractor. Left mouse button display interaction (crosshair navigation) is blocked while this interactor is enabled, allowing plain left clicks for point placement.

Constructor & Destructor Documentation

◆ PointInteractor()

mitk::nnInteractive::PointInteractor::PointInteractor ( )

Constructs a PointInteractor with InteractionType::Point.

◆ ~PointInteractor()

mitk::nnInteractive::PointInteractor::~PointInteractor ( )

override

Destructor. Calls OnReset() to clean up data nodes.

Member Function Documentation

◆ GetLastPoint()

std::optional<Point3D> mitk::nnInteractive::PointInteractor::GetLastPoint ( ) const

Returns the most recently placed point for the current prompt type.

Returns: The last point's 3D coordinates if at least one point exists for the current prompt type, std::nullopt otherwise.

See also: GetCurrentPromptType()

◆ HasInteractions()

bool mitk::nnInteractive::PointInteractor::HasInteractions ( ) const

overridevirtual

Checks whether any points have been placed.

Returns: true if at least one point exists in any PointSet for any prompt type, false otherwise.

Implements mitk::nnInteractive::Interactor.

◆ RemoveLastInteraction()

void mitk::nnInteractive::PointInteractor::RemoveLastInteraction ( PromptType promptType )

overridevirtual

Removes the most recently placed point for the given prompt type.

A no-op if no point set exists for promptType or it is already empty. The point set node is left in place (it may be the actively bound node); empty sets are cleaned up by OnDisable() / OnReset() as before.

Parameters

[in] promptType The prompt type whose last point should be removed.
