Struct

PangoLayoutLine

Description [src]

struct PangoLayoutLine {
  PangoLayout* layout;
  gint start_index;
  gint length;
  GSList* runs;
  guint is_paragraph_start : 1;
  guint resolved_dir : 3;
}

A PangoLayoutLine represents one of the lines resulting from laying out a paragraph via PangoLayout.

PangoLayoutLine structures are obtained by calling pango_layout_get_line() and are only valid until the text, attributes, or settings of the parent PangoLayout are modified.

Structure members

layout: The layout this line belongs to, might be NULL.
start_index: Start of line as byte index into layout->text.
length: Length of line in bytes.
runs: List of runs in the line, from left to right.
is_paragraph_start: TRUE if this is the first line of the paragraph.
resolved_dir: Resolved PangoDirection of line.
