Layouting symbols in the diagram

We provide an API to layout presentation elements in a diagram using different strategies (layouter), see:

com.nomagic.magicdraw.uml.symbols.layout.Layouting

//layout using the default diagram layouter
AbstractDiagramPresentationElement diagramView = ...;
diagramView.open();
Layouting.layout(diagramView);

JAVA

//layout the selected symbols in the diagram using the default diagram layouter
AbstractDiagramPresentationElement diagramView = ...;
diagramView.open();

List<PresentationElement> symbolsToLayout = ...;
diagramView.setSelected(symbolsToLayout);
Layouting.layout(diagramView);

JAVA

//layout using any of the available layouters
AbstractDiagramPresentationElement diagram  = ...;
diagram.open()
Layouting.layout(diagram, Layouting.HIERARCHIC_DIAGRAM_LAYOUTER);

JAVA

Make sure the diagram is opened and the session is closed before doing a diagram layout. These are the current limitation of layout API
