All Implemented Interfaces:
IActivatable, IAdaptable, IAdaptable.Bound<IViewer>, IDisposable, IContentPart<javafx.scene.Group>, ITransformableContentPart<javafx.scene.Group>, IVisualPart<javafx.scene.Group>
Direct Known Subclasses:
EdgeLabelPart, NodeLabelPart
public abstract class AbstractLabelPart extends AbstractContentPart<javafx.scene.Group> implements ITransformableContentPart<javafx.scene.Group>
Abstract base class for external labels, i.e. labels that are not part of the visualization of another controller. The standard node label is part of the node part's visualization. However, edge labels are implemented as external labels, for example.
