Class RMEditorProxGuide

java.lang.Object
com.reportmill.editor.RMEditorProxGuide
public class RMEditorProxGuide extends Object
This class offers some methods to provide "proximity guides" for RMEditor. This feature draws lines indicating when dragged shapes share alignments with some of their neighboring shapes (and also snaps to these alignments, too).

    • markGuidelinesDirty

      public static void markGuidelinesDirty(RMEditor anEditor)
      Runs through the guideline list and asks the editor to repaint the enclosing rect.

    • paintProximityGuides

      public static void paintProximityGuides(RMEditor anEditor, Graphics2D g)
      Called by the editor to paint all the guidelines in the guideline list

    • setIncludesSuperselectedShape

      public static void setIncludesSuperselectedShape(boolean aFlag)
      If this flag is set, the bounds of the parent shape are also checked for proximity.

    • getCandidateShapes

      public static List getCandidateShapes(RMEditor anEditor)
      Returns the list of shapes to be included in the proximity check.

    • createGuidelines

      public static void createGuidelines(RMEditor anEditor)

    • createGuidelines

      public static void createGuidelines(RMEditor anEditor, RMShape parent, RMRect bounds, List candidateShapes)
      Recalculates all the proximity guides and marks dirty region in editor for old & new guide regions. Guides are calculated between the bounds rectangle and each of the candidateShapes, within the parent RMShape.

    • pointSnappedToProximityGuides

      public static RMPoint pointSnappedToProximityGuides(RMEditor anEditor, RMPoint aPoint)
      Returns the given point snapped to relevant proximity guides.

    • pointSnappedToProximityGuides

      public static RMPoint pointSnappedToProximityGuides(RMEditor anEditor, RMPoint aPoint, int dragMode)
      Returns the given point snapped to relevant proxity guides for a given drag mode.
