Unwanted child nodes resize [message #1766571]

Layouting my diagram using default arange all or any ELK layouts leads to unwanted nodes resize that are styled with this square.

index.php/fa/29772/0/

Is there a way to avoid this behavior ?

Noticed a SiriusDiagramUiInternalPreferencesKeys.PREF_AUTOSIZE_ON_ARRANGE pref which setting it to false didn't avoid the resize.

Any idea is welcome.

Hi Aurelien,

which size did they have at the start, and which size did they end up with after ELK layout?

Cheers,
Chris

Do you set any paddings on your nodes?

Here are my option and invocation (using ElkPadding) :

DiagramLayoutEngine.Parameters params = new DiagramLayoutEngine.Parameters();

params.getGlobalSettings()

.setProperty(CoreOptions.ANIMATE, animation)
.setProperty(CoreOptions.LAYOUT_ANCESTORS, false)
.setProperty(CoreOptions.NODE_SIZE_MINIMUM, new KVector(100d, 50d))
.setProperty(CoreOptions.NODE_SIZE_CONSTRAINTS, SizeConstraint.fixed())
.setProperty(CoreOptions.HIERARCHY_HANDLING, HierarchyHandling.INCLUDE_CHILDREN)
.setProperty(CoreOptions.NODE_SIZE_OPTIONS, EnumSet.of(SizeOptions.DEFAULT_MINIMUM_SIZE))
.setProperty(CoreOptions.PROGRESS_BAR, progressDialog)
.setProperty(CoreOptions.ZOOM_TO_FIT, zoomToFit)
.setProperty(CoreOptions.PADDING, new ElkPadding(24, 12, 12, 12))
.setProperty(CoreOptions.ALGORITHM, "org.eclipse.elk.layered.layered")
;

params.addLayoutRun().configure(ElkNode.class)

.setProperty(LayeredOptionsOpt1.SPACING_NODE_NODE, 10d)
.setProperty(LayeredOptionsOpt1.DIRECTION, Direction.RIGHT)
.setProperty(LayeredOptionsOpt1.EDGE_THICKNESS, 10d)
.setProperty(LayeredOptionsOpt1.LAYERING_STRATEGY, LayeringStrategy.NETWORK_SIMPLEX)
.setProperty(LayeredOptionsOpt1.COMPACTION_CONNECTED_COMPONENTS, true)
.setProperty(LayeredOptionsOpt1.EDGE_ROUTING, EdgeRouting.ORTHOGONAL)
.setProperty(LayeredOptionsOpt1.PADDING, new ElkPadding(24, 12, 12, 12))
.setProperty(LayeredOptionsOpt1.LAYERING_NODE_PROMOTION_STRATEGY, NodePromotionStrategy.NONE)
.setProperty(LayeredOptionsOpt1.NODE_PLACEMENT_NETWORK_SIMPLEX_NODE_FLEXIBILITY, NodeFlexibility.NONE)
.setProperty(LayeredOptionsOpt1.NODE_SIZE_CONSTRAINTS, SizeConstraint.fixed())
.setProperty(LayeredOptionsOpt1.NODE_SIZE_OPTIONS, EnumSet.of(SizeOptions.DEFAULT_MINIMUM_SIZE))
.setProperty(LayeredOptionsOpt1.PORT_BORDER_OFFSET, 0d)
.setProperty(LayeredOptionsOpt1.SPACING_COMPONENT_COMPONENT, 0d)
.setProperty(LayeredOptionsOpt1.SPACING_NODE_NODE, 0d)

.setProperty(LayeredOptionsOpt1.LAYERING_LAYER_CONSTRAINT, LayerConstraint.NONE)
.setProperty(LayeredOptionsOpt1.PORT_LABELS_PLACEMENT, PortLabelPlacement.INSIDE)
;

DiagramLayoutEngine.invokeLayout(editorPart, diagramPart, null, params);
