directionLeadingToTrailing
Arrange objects in order based on the normal text flow for the current user interface language. In left-to-right languages (like English), this arrangement results in the first object being placed farthest to the left, the next one to its right, and so on. In right-to-left languages (like Arabic or Hebrew), the ordering is reversed.
