Details

The pango:layout-line structure represents one of the lines resulting from laying out a paragraph via a pango:layout object. The pango:layout-line instances are obtained by calling the pango:layout-line function and are only valid until the text, attributes, or settings of the parent pango:layout object are modified. Routines for rendering pango:layout objects are provided in code specific to each rendering system.
