JavaFX - Adding nodes to ScrollPane with correct scrolling direction

JavaFX - Adding nodes to ScrollPane with correct scrolling direction

I have a ScrollPane in my scene and would like to add a series of Nodes to
it. The exact amount must be dynamic. I've been testing the concept with
Label nodes and can successfully add as many Labels as I want to the
content of the ScrollPane (currently a VBox).
My problem is figuring out how to allow the user to scroll normally
through the ScrollPane full of Nodes. The content matches pace with the
scrollbar; that is, when I scroll down, the content moves down. I scroll
up, the content scrolls up. So if I have 10 Labels, only five of which are
currently visible, the instinctive action to see the other five would be
to scroll down. Unfortunately, this just moves the entire content down,
exposing empty space up top and hiding more of the Labels.
I can post some sample code if that helps, but the gist of my plan of
attack is this:
ScrollPane sp = new ScrollPane();
VBox content = new VBox();
sp.setContent(content);
for (int i = 0; i < 10; i++)
{
Label label = new Label("Label " + i);
content.setPrefHeight(content.getPrefHeight() + label.getPrefHeight());
content.getChildren().add(label);
}
Because I use a VBox, the Labels are stacked (in the Y axis) atop one
another, which is what I want. As more Labels are added, the ScrollBar
needs to reflect the increased size of the VBox. I've tried a few
approaches to get this to work, including ScrollPane.setVmax() method,
which is ok, but I still have the issue of the scroll direction moving the
content in the wrong direction. I've also tried an EventHandler and
EventFilter to modify values accordingly, still without solving the
problem of scrolls not moving the content in the right direction.
The answer seems so simple, yet the it continues to evade me, even after
many long hours messing around with the code.
