-fx-orientationOrientationThe orientation of the segmented bar.

public class SegmentedBar<T extends SegmentedBar.Segment> extends javafx.scene.control.Control
A control that makes it easy to create a horizontal bar that visualises the segmentation of a total value. It consists of several segments, each segment is representing a value. The sum of all values is the total value of the bar (see totalProperty()). The bar can be customised by setting a factory for the creation of the segment views.

Example 1:

factory. 
SegmentedBar bar = new SegmentedBar();
bar.getSegments().addAll(
    new Segment(10, "10"),
    new Segment(10, "10"),
    new Segment(10, "10"),
    new Segment(10, "10"),
    new Segment(10, "10"),
    new Segment(50, "50"));

Example 2:

various media types (photos, videos, music, ...). A special info node factory is supplied to present a useful detailed description of the segment. The type "TypeSegment" is a subclass of SegmentedBar.Segment 
typesBar.setSegmentViewFactory(segment -> new TypeSegmentView(segment));
typesBar.setInfoNodeFactory(segment -> new InfoLabel(segment.getText() + " " + segment.getValue() + " GB"));
typesBar.getSegments().addAll(
    new TypeSegment(14, MediaType.PHOTOS),
    new TypeSegment(32, MediaType.VIDEO),
    new TypeSegment(9, MediaType.APPS),
    new TypeSegment(40, MediaType.MUSIC),
    new TypeSegment(5, MediaType.OTHER),
    new TypeSegment(35, MediaType.FREE));
