	new Pango.GlyphString () Create a new Pango.GlyphString Create a new Pango.GlyphString
	copy () : Pango.GlyphString Copy a glyph string and associated storage. Copy a glyph string and associated storage. should be freed with pango_glyph_string_free(), or NULL if string was NULL. Returns: Pango.GlyphString the newly allocated PangoGlyphString, which	Pango.GlyphString
	extents (Font *font, Rectangle ink_rect, Rectangle logical_rect) : none Compute the logical and ink extents of a glyph string. Compute the logical and ink extents of a glyph string. See the documentation for pango_font_get_glyph_extents() for details about the interpretation of the rectangles. Parameters: Pango.Font font* Required (not null) a PangoFont Pango.Rectangle ink_rect Required (not null) rectangle used to store the extents of the glyph string as drawn or NULL to indicate that the result is not needed. Pango.Rectangle logical_rect Required (not null) rectangle used to store the logical extents of the glyph string or NULL to indicate that the result is not needed. Returns: none	Pango.GlyphString
	extents_range (gint32 *start, gint32 end, Font font, Rectangle ink_rect, Rectangle logical_rect) : none or NULL* to indicate that the result is not needed. or NULL to indicate that the result is not needed. or NULL to indicate that the result is not needed. Computes the extents of a sub-portion of a glyph string. The extents are relative to the start of the glyph string range (the origin of their coordinate system is at the start of the range, not at the start of the entire glyph string). Parameters: gint32 start Required (not null) start index gint32 end Required (not null) end index (the range is the set of bytes with Pango.Font font Required (not null) a PangoFont Pango.Rectangle ink_rect Required (not null) rectangle used to store the extents of the glyph string range as drawn Pango.Rectangle logical_rect Required (not null) rectangle used to store the logical extents of the glyph string range Returns: none	Pango.GlyphString
	free () : none Free a glyph string and associated storage. Free a glyph string and associated storage. Returns: none	Pango.GlyphString
	get_logical_widths (String *text, gint32 length, gint32 embedding_level, gint32 logical_widths) : none Given a PangoGlyphString* resulting from pango_shape() and the corresponding text, determine the screen width corresponding to each character. Given a PangoGlyphString resulting from pango_shape() and the corresponding text, determine the screen width corresponding to each character. When multiple characters compose a single cluster, the width of the entire cluster is divided equally among the characters. See also pango_glyph_item_get_logical_widths(). Parameters: String text Required (not null) the text corresponding to the glyphs gint32 length Required (not null) the length of text, in bytes gint32 embedding_level Required (not null) the embedding level of the string gint32 logical_widths Required (not null) an array whose length is the number of characters in text (equal to g_utf8_strlen (text, length) unless text has NUL bytes) to be filled in with the resulting character widths. Returns: none	Pango.GlyphString
	get_width () : gint32 Computes the logical width of the glyph string as can also be computed using pango_glyph_string_extents(). Computes the logical width of the glyph string as can also be computed using pango_glyph_string_extents(). However, since this only computes the width, it's much faster. This is in fact only a convenience function that computes the sum of geometry.width for each glyph in the glyphs. Returns: gint32 the logical width of the glyph string.	Pango.GlyphString
	index_to_x (String *text, gint32 length, Analysis analysis, gint32 index_, gboolean trailing, gint32 x_pos) : none Converts from character position to x position. Converts from character position to x position. (X position is measured from the left edge of the run). Character positions are computed by dividing up each cluster into equal portions. Parameters: String text* Required (not null) the text for the run gint32 length Required (not null) the number of bytes (not characters) in text. Pango.Analysis analysis Required (not null) the analysis information return from pango_itemize() gint32 index_ Required (not null) the byte index within text gboolean trailing Required (not null) whether we should compute the result for the beginning (FALSE) or end (TRUE) of the character. gint32 x_pos Required (not null) location to store result Returns: none	Pango.GlyphString
	set_size (gint32 *new_len) : none Resize a glyph string to the given length. Resize a glyph string to the given length. Parameters: gint32 new_len* Required (not null) the new length of the string. Returns: none	Pango.GlyphString
	x_to_index (String *text, gint32 length, Analysis analysis, gint32 x_pos, gint32 index_, gint32 trailing) : none Convert from x offset to character position. 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. Parameters: String text* Required (not null) the text for the run gint32 length Required (not null) the number of bytes (not characters) in text. Pango.Analysis analysis Required (not null) the analysis information return from pango_itemize() gint32 x_pos Required (not null) the x offset (in Pango units) gint32 index_ Required (not null) location to store calculated byte index within text gint32 trailing Required (not null) location to store a boolean indicating whether the user clicked on the leading or trailing edge of the character. Returns: none	Pango.GlyphString
