Grab mouse position inside scroll pane

Question

How do I get the mouse position inside a scroll pane in javafx? I have an app that does a drag and drop operation inside it, and I need that information to position the node on the screen.

The scroll pane is Pannable.

If you need to see any more pieces of Có just ask, but I think I posted what needed understanding to be clear now.

public EventHandler<? super MouseEvent> getStartClassDrag(Node n, TipoClasse t) {
    return (e) ->{
        //this.ac_comp.setDisable(true);
        ClipboardContent cc = new ClipboardContent();
        cc.putUrl(FXMLFile.CLASSE);
        n.startDragAndDrop(TransferMode.ANY).setContent(cc);

        //Trecho de código original
        //sp_desktop.onDragDroppedProperty().set((evet) -> {

        //Solução
        pn_desktop.onDragDroppedProperty().set((evet) -> {
            if(evet.getDragboard().getUrl().equals(FXMLFile.CLASSE)) {
                FXMLLoader loader = new FXMLLoader(getClass().getResource(FXMLFile.CLASSE));
                try {
                    loader.load();
                } catch (Exception err) { err.printStackTrace(); }
                ClasseController controller = loader.getController();
                controller.inicializar(this);
                controller.classe.setTipo(t);
                classes.add(controller);

                Point2D teste = new Point2D(evet.getX() + sp_desktop.getHvalue(), evet.getY() + sp_desktop.getVvalue());
                System.out.println(sp_desktop.getHvalue() + "x" + sp_desktop.getVvalue());

                teste = sp_desktop.parentToLocal(teste);

                relocateToPoint(teste.getX(), teste.getY(), controller.ap_classe);
                controller.ap_classe.setVisible(true);

            }
        });

        //Trecho de código original
        //sp_desktop.onDragOverProperty().set((evento) -> {

        //Solução
        pn_desktop.onDragOverProperty().set((evento) -> {
            if(evento.getDragboard().getUrl().equals(FXMLFile.CLASSE)) {
                evento.acceptTransferModes(TransferMode.ANY);
            }
            evento.consume();
        });

        n.onDragDoneProperty().set((aux) ->{
            sp_desktop.onDragDroppedProperty().set(null);
            sp_desktop.onDragOverProperty().set(null);
            ac_comp.setDisable(false);

        });
    };
}

protected void relocateToPoint(double x, double y, AnchorPane no) {
    no.setVisible(true);
    pn_desktop.getChildren().remove(no);
    pn_desktop.getChildren().add(no);
    no.setLayoutX(x - (no.getWidth() / 2));
    no.setLayoutY(y - (no.getHeight() / 2));
}

I have an example I made recently to move my window. Check if the code below helps in the solution.

    double xOffset = 0;
    double yOffset = 0;

    scrollPane.setOnMousePressed((MouseEvent event) -> {
        // Nesse trecho de código será capturado a posição do mouse
        xOffset = event.getSceneX();
        yOffset = event.getSceneY();
    });
    scrollPane.setOnMouseDragged((MouseEvent event) -> {
        primaryStage.setX(event.getScreenX() - xOffset);
        primaryStage.setY(event.getScreenY() - yOffset);
    });
