PangoLayoutset_auto_dir

since: 1.4

Declaration [src]

void
pango_layout_set_auto_dir (
  PangoLayout* layout,
  gboolean auto_dir
)

Description [src]

Sets whether to calculate the base direction for the layout according to its contents.

When this flag is on (the default), then paragraphs in layout that begin with strong right-to-left characters (Arabic and Hebrew principally), will have right-to-left layout, paragraphs with letters from other scripts will have left-to-right layout. Paragraphs with only neutral characters get their direction from the surrounding paragraphs.

When FALSE, the choice between left-to-right and right-to-left layout is done according to the base direction of the layout’s PangoContext. (See pango_context_set_base_dir()).

When the auto-computed direction of a paragraph differs from the base direction of the context, the interpretation of PANGO_ALIGN_LEFT and PANGO_ALIGN_RIGHT are swapped.

Available since: 1.4

Parameters

auto_dir

Type: gboolean

If TRUE, compute the bidirectional base direction from the layout’s contents.
