Direction
===================================================================

.. currentmodule:: gi.repository.Pango





.. class:: Direction
   :no-contents-entry:






``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 :obj:`~gi.repository.Pango.unichar_direction`
and :obj:`~gi.repository.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 :obj:`~gi.repository.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.
