Example 1 with Layout

use of org.kie.workbench.common.stunner.core.graph.processing.layout.Layout in project kie-wb-common by kiegroup.

the class LayoutHelper method applyLayout.

public void applyLayout(final Diagram diagram, final LayoutExecutor layoutExecutor, final boolean overrideCurrentLayout) {
    final Graph<?, Node> graph = diagram.getGraph();
    if (graph != null && (overrideCurrentLayout || !this.layoutService.hasLayoutInformation(graph))) {
        final Layout layout = this.layoutService.createLayout(graph);
        layoutExecutor.applyLayout(layout, graph);
        for (final Node node : graph.nodes()) {
            if (CanvasLayoutUtils.isCanvasRoot(diagram, node)) {
                if (node.getContent() instanceof HasBounds) {
                    ((HasBounds) node.getContent()).setBounds(Bounds.create(0, 0, 0, 0));
                }
            }
        }
    }
}
