Class AnnotationPainter

java.lang.Object
org.eclipse.jface.text.source.AnnotationPainter
All Implemented Interfaces:
EventListener, IPainter, ITextPresentationListener, IAnnotationModelListener, IAnnotationModelListenerExtension, PaintListener
public class AnnotationPainter extends Object implements IPainter, PaintListener, IAnnotationModelListener, IAnnotationModelListenerExtension, ITextPresentationListener
Paints decorations for annotations provided by an annotation model and/or highlights them in the associated source viewer.

The annotation painter can be configured with drawing strategies. A drawing strategy defines the visual presentation of a particular type of annotation decoration.

Clients usually instantiate and configure objects of this class.

    • addAnnotationType

      public void addAnnotationType(Object annotationType, Object strategyID)
      Adds the given annotation type to the list of annotation types whose annotations should be painted by this painter using the given strategy. If the annotation type is already in this list, the old strategy gets replaced.
      Parameters:
      annotationType - the annotation type
      strategyID - the id of the drawing or text style strategy that should be used for this annotation type
      Since:
      3.0

    • addDrawingStrategy

      public void addDrawingStrategy(Object id, AnnotationPainter.IDrawingStrategy strategy)
      Registers a new drawing strategy under the given ID. If there is already a strategy registered under id, the old strategy gets replaced.

      The given id can be referenced when adding annotation types, see addAnnotationType(Object, Object).

      Parameters:
      id - the identifier under which the strategy can be referenced, not null
      strategy - the new strategy
      Since:
      3.0

    • addTextStyleStrategy

      public void addTextStyleStrategy(Object id, AnnotationPainter.ITextStyleStrategy strategy)
      Registers a new drawing strategy under the given ID. If there is already a strategy registered under id, the old strategy gets replaced.

      The given id can be referenced when adding annotation types, see addAnnotationType(Object, Object).

      Note: The annotations will only be painted if this painter has been registered as text presentation listener on the viewer.

      Parameters:
      id - the identifier under which the strategy can be referenced, not null
      strategy - the new strategy
