Method sp.setVvalue(app.spvalue.intValue());
doesn't scroll vbox to desired position.
mvPane = new VBox();
mvPane.setStyle("-fx-background-color: #fff;");
GetPlayList(app,root);
sp = new ScrollPane();
sp.setVbarPolicy(ScrollPane.ScrollBarPolicy.AS_NEEDED);
sp.setContent(mvPane);
sp.setVvalue(40);
setCenter(sp);
sp.getVvalue();
Function GetPlayList adds many labels.
If you are talking about JavaFX 2.0, and its scrollPane, then Hvalue and Vvalue properties are working well, but the matter, look like, that their values are doubles from range [0.0 .. 1.0], so, when you set int value, it will not work fine.
