### Enumeration

# PangoDirection

#### Declaration

    enum Pango.Direction

#### Description [src]

`PangoDirection` represents a direction in the Unicode bidirectional algorithm.

Not every value in this enumeration makes sense for every usage of `PangoDirection`; for example, the return value of `pango_unichar_direction()` and `pango_find_base_dir()` cannot be `PANGO_DIRECTION_WEAK_LTR` or `PANGO_DIRECTION_WEAK_RTL`, since every character is either neutral or has a strong direction; on the other hand `PANGO_DIRECTION_NEUTRAL` doesn’t make sense to pass to `pango_itemize_with_base_dir()`.

The `PANGO_DIRECTION_TTB_LTR`, `PANGO_DIRECTION_TTB_RTL` values come from an earlier interpretation of this enumeration as the writing direction of a block of text and are no longer used. See `PangoGravity` for how vertical text is handled in Pango.

If you are interested in text direction, you should really use fribidi directly. `PangoDirection` is only retained because it is used in some public apis.
