How to disable automatic layout for a JavaFX Group?

I have a Group whose coordinate transformations I want to manage completely myself. The built-in layoutX and layoutY properties are messing this up, and I would like to disable them completely.

There seems to be at least two ways of doing this. relocate(0,0) or simply setting the properties to 0. But doing this in the Group construction is too early; the values are 0 there anyways.

So: how do I tell the Group to not bother doing layouting?

Naturally, I can also leave the layoutX|Y as they are, and compensate for them in my own transforms. That's the plan B.

The question is a bit hard to understand, but I'm guessing you have a Group in a managed layout Pane of some kind (such as a StackPane or VBox) but you don't want the Group's layout values being set by the layout pane -- in which case you can make the group unmanaged.

For example, in the following code, the unmanaged nature of the group causes it to have layout co-ordinates of 0,0 rather than layout co-ordinates of 50,60 which StackPane would usually set to center it inside the parent StackPane.

Group group = new Group(new Rectangle(100, 80));
group.setManaged(false);
StackPane container = new StackPane();
container.setMinSize(StackPane.USE_PREF_SIZE, StackPane.USE_PREF_SIZE);
container.setPrefSize(200, 200);
container.setMaxSize(StackPane.USE_PREF_SIZE, StackPane.USE_PREF_SIZE);
container.getChildren().add(group);
