Subject Re: A split pane inside any other pane seems not to work?

No, BoxPane just isn't designed to work that way. BoxPane lays components out in a horizontal
or vertical row. A horizontal box pane will optionally size its children to fill the vertical
space, but it doesn't impose any constraints in the horizontal direction. Vertical box panes
behave similarly.

BoxPane as an ancestor. I'd recommend using a TablePane instead of a BoxPane in this case.

And the SplitPane apparently gets a height of 0 as long as neither the SplitPane nor any of
the contained components get an explicit preferredWidth.
