From source file:com.ucu.seguridad.views.AbstractFxmlView.java

/**
 * Scene Builder creates for each FXML document a root container. This method omits the root container (e.g.
 * {@link AnchorPane}) and gives you the access to its first child.

 * @return the first child of the {@link AnchorPane}

public Node getViewWithoutRootContainer() {

    ObservableList<Node> children = getView().getChildrenUnmodifiable();
    if (children.isEmpty()) {
        return null;
    }

    return children.listIterator().next();
