set_auto_dir
Description:
Sets whether to calculate the base direction for the layout according to its contents.
When this flag is on (the default), then paragraphs in this 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 [method@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.
Parameters:
| this |
a `PangoLayout` |
| auto_dir |
if true, compute the bidirectional base direction from the layout's contents |
