This can be achieved by using BorderPane, or if that is not sufficient (ie the parent is not a PaneContainer), you can create your own component that utilizes some css/js solution that can be found on the web.
You can also use RoundedColumn provided by echo2consultas.jar.
If you combine 2 RoundedColumn the first one with TopRoundedCorner to On and BottomRoundedColumn to False and the second one (False/True) you obtain exactly the same output.
