Creating Inner Swimlanes Programatically

[magicdrawUser102983]

I am trying to programmatically create a swimlane with inner swimlanes. I can get the ActivityPartition objects correctly in the Containment tree, but I cannot create the corresponding SwimlaneView object. This is the code I have so far

Code: Select all

         smObj = SessionManager.getInstance();
         smObj.createSession(project, "Object Creator " + UUID.randomUUID().toString());

         DiagramPresentationElement diagram = project.getActiveDiagram();
         PresentationElementsManager presentationElementsManager = PresentationElementsManager.getInstance();

         ActivityPartition activityPartition = project.getElementsFactory().createActivityPartitionInstance();
         activityPartition.setName("Parent");
         activityPartition.setOwner(diagram.getDiagram().getOwner());

         ActivityPartition child1 = project.getElementsFactory().createActivityPartitionInstance();
         child1.setName("Child 1");
         child1.setOwner(activityPartition);

         ActivityPartition child2 = project.getElementsFactory().createActivityPartitionInstance();
         child2.setName("Child 2");
         child2.setOwner(activityPartition);

         SwimlaneView parentLanes = presentationElementsManager.createSwimlane(Arrays.asList(activityPartition),
               Collections.emptyList(), diagram);

         SwimlaneView childLanes = presentationElementsManager.createSwimlane(Arrays.asList(child1, child2),
               Collections.emptyList(), diagram);

         for (SwimlaneCellView cell : parentLanes.getAllCells()) {
            childLanes.setParent(cell);
         }

         presentationElementsManager.movePresentationElement(parentLanes, new Point(50, 50));

         smObj.closeSession(project);
         smObj = null;


I get a result which I attached, but it is not valid.

Any guidance on how to create inner swimlanes programmatically would be greatly appreciated.

So I got the answer from the great MagicDraw customer support, I am posting it here in case anyone else needs a solution to a similar issue.

Code: Select all

      //Collect required general variables: project, diagram etc.
      DiagramPresentationElement diagram = project.getActiveDiagram();

      //Create command. This is same as SessionManager.createSession(), but we will need MacroCommand for further code.
      CommandHistory history = project.getCommandHistory();
      MacroCommand command = history.startCommand("CREATE SWIMLANE");

      //This code creates partitions, just as you provided. Parent, child1, child2.
      ActivityPartition activityPartition = project.getElementsFactory().createActivityPartitionInstance();
      activityPartition.setName("Parent");
      activityPartition.setOwner(diagram.getDiagram().getOwner());

      ActivityPartition child1 = project.getElementsFactory().createActivityPartitionInstance();
      child1.setName("Child 1");
      child1.setOwner(activityPartition);

      ActivityPartition child2 = project.getElementsFactory().createActivityPartitionInstance();
      child2.setName("Child 2");
      child2.setOwner(activityPartition);

      //Initialize initial swimlane and create it via SymbolCreator. Can be done via PresentationElementsManager too.
      SwimlaneView swimlaneView = new SwimlaneView(diagram);
      final SymbolCreator symbolCreator = new SymbolCreator(diagram);
      symbolCreator.setSelectCreatedSymbol(false);
      swimlaneView = (SwimlaneView) symbolCreator.addSymbol(command, swimlaneView);
      swimlaneView.setLocation(200, 100);

      //Initialize swimlanesBuilder. It will construct swimlaneHeaderView. False flags indicate isVertical. False => horizontal.
      SwimlaneBuilder builder = new SwimlaneBuilder(swimlaneView);
      SwimlaneHeaderView swimlaneHeaderView = builder.addSwimlane(activityPartition, swimlaneView.getSwimlanes(false), swimlaneView, false);

      //Create SwimlanesStructure.
      List<MultiSwimlaneStructure> multiStructures = new ArrayList<>();
      multiStructures.add(new MultiSwimlaneStructure(null, child1));
      multiStructures.add(new MultiSwimlaneStructure(null, child2));

      //Create swimlane and execute its creation command.
      MacroCommand cmd = new AddSwimlane(swimlaneView, false, swimlaneHeaderView, false, true, multiStructures);
      cmd.execute();
      history.complete();

Where is the documentaion SwimlaneBuilder? I tried searching it but no results
