Example 1 with AbstractBorderItemEditPart

use of org.eclipse.gmf.runtime.diagram.ui.editparts.AbstractBorderItemEditPart in project elk by eclipse.

the class ElkLayoutProvider method canLayoutNodes.

/**
 * {@inheritDoc}<br>
 * <br>
 * This method returns <code>true</code> only for {@link IGraphicalEditPart IGraphicalEditParts}
 * whose figures are visible and that contain at least a {@link ShapeNodeEditPart}, which is not
 * an {@link AbstractBorderItemEditPart} or an {@link AbstractImageEditPart}.<br>
 * <br>
 * In short, returns only true if the provided edit part contains children that can be layouted.
