A tab in a paragraph style, storing an alignment type and location.
- Core Text
Core Text supports five alignment types:
CTText. These alignment types are absolute, not based on the line sweep direction of text.
For example, tabbed text is always positioned to the left of a right-aligned tab, whether the line sweep direction is left to right or right to left. A tab's location, on the other hand, is relative to the back margin. A tab set at 1.5 inches, for example, is at 1.5 inches from the right in right-to-left text.
