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

Example 1 with NodeLabelPositionProvider

use of org.eclipse.sirius.components.diagrams.layout.incremental.provider.NodeLabelPositionProvider 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);
        }
    }
}
