Examples with EdgeLabelPositionProvider org.eclipse.sirius.components.diagrams.layout.incremental.provider.EdgeLabelPositionProvider used on opensource projects

Example 1 with EdgeLabelPositionProvider

use of org.eclipse.sirius.components.diagrams.layout.incremental.provider.EdgeLabelPositionProvider in project sirius-components by eclipse-sirius.

the class IncrementalLayoutEngine method layout.

public void layout(Optional<IDiagramEvent> optionalDiagramElementEvent, DiagramLayoutData diagram, ISiriusWebLayoutConfigurator layoutConfigurator) {
    this.borderNodeLabelPositionProvider = new BorderNodeLabelPositionProvider();
    this.nodeLabelPositionProvider = new NodeLabelPositionProvider(layoutConfigurator);
    this.edgeLabelPositionProvider = new EdgeLabelPositionProvider(layoutConfigurator);
    // first we layout all the nodes
    for (NodeLayoutData node : diagram.getChildrenNodes()) {
        this.layoutNode(optionalDiagramElementEvent, node, layoutConfigurator);
    }
    // resolve overlaps due to previous changes
    new OverlapsUpdater().update(diagram);
    // resize according to the content
    new ContainmentUpdater().update(diagram);
    // finally we recompute the edges that needs to
    for (EdgeLayoutData edge : diagram.getEdges()) {
        if (this.hasChanged(edge.getSource()) || this.hasChanged(edge.getTarget()) || !this.isLabelPositioned(edge) || !this.isEdgePositioned(edge)) {
            this.layoutEdge(optionalDiagramElementEvent, edge);
        }
    }
}

Example 2 with EdgeLabelPositionProvider

use of org.eclipse.sirius.components.diagrams.layout.incremental.provider.EdgeLabelPositionProvider in project sirius-components by eclipse-sirius.

the class EdgeLabelPositionProviderTests method testEdgeLabelBoundsPosition.

@Test
public void testEdgeLabelBoundsPosition() {
    EdgeLayoutData edgeLayoutData = this.createEdgeLayoutData(this.createDiagramLayoutData());
    EdgeLabelPositionProvider labelBoundsProvider = new EdgeLabelPositionProvider(new LayoutConfiguratorRegistry(List.of()).getDefaultLayoutConfigurator());
    Position centerPosition = labelBoundsProvider.getCenterPosition(edgeLayoutData, edgeLayoutData.getCenterLabel());
    assertThat(centerPosition.getX()).isCloseTo(267.539, Offset.offset(0.0001));
    assertThat(centerPosition.getY()).isCloseTo(103, Offset.offset(0.0001));
