Declaration [src]
void
pango_glyph_string_x_to_index (
  PangoGlyphString* glyphs,

  int* trailing
)
Description [src]
Convert from x offset to character position.
Character positions are computed by dividing up each cluster into equal portions. In scripts where positioning within a cluster is not allowed (such as Thai), the returned value may not be a valid cursor position; the caller must combine the result with the logical attributes for the text to compute the valid cursor position.
