Detailed Documentation
~~~~~~~~~~~~~~~~~~~~~~

Logical :ref:`UI <doxid-namespace_e_e_1_1_u_i>` reading/layout direction of a widget subtree.

The :ref:`UI <doxid-namespace_e_e_1_1_u_i>` direction is independent from the direction of the text a widget renders: a right-to-left :ref:`UI <doxid-namespace_e_e_1_1_u_i>` can contain left-to-right paragraphs and vice versa. It decides how logical concepts (``start``, ``end``, ``inline-start``, ``inline-end``, ``layout-to-start-of``, ...) resolve to physical edges. Physical concepts (``left``, ``right``, ``margin-left``, ``UI_HALIGN_LEFT``, ...) never change their meaning.
