Method / Constructor		Defined By
	new Pango.GlyphItem () Create a new Pango.GlyphItem Create a new Pango.GlyphItem
	copy () : Pango.GlyphItem Make a deep copy of an existing PangoGlyphItem structure. Make a deep copy of an existing PangoGlyphItem structure. be freed with pango_glyph_item_free(), or NULL if orig was NULL. Returns: Pango.GlyphItem the newly allocated PangoGlyphItem, which should	Pango.GlyphItem
	free () : none Frees a PangoGlyphItem and resources to which it points. Frees a PangoGlyphItem and resources to which it points. Returns: none	Pango.GlyphItem
	get_logical_widths (String *text, gint32 logical_widths) : none Given a PangoGlyphItem* and the corresponding text, determine the screen width corresponding to each character. Given a PangoGlyphItem 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_string_get_logical_widths(). Parameters: String text Required (not null) text that glyph_item corresponds to (glyph_item->item->offset is an offset from the start of text) gint32 logical_widths Required (not null) an array whose length is the number of characters in glyph_item (equal to glyph_item->item->num_chars) to be filled in with the resulting character widths. Returns: none	Pango.GlyphItem
	letter_space (String *text, LogAttr log_attrs, gint32 letter_spacing) : none Adds spacing between the graphemes of glyph_item* to give the effect of typographic letter spacing. Adds spacing between the graphemes of glyph_item to give the effect of typographic letter spacing. Parameters: String text Required (not null) text that glyph_item corresponds to (glyph_item->item->offset is an offset from the start of text) Pango.LogAttr log_attrs Required (not null) logical attributes for the item (the first logical attribute refers to the position before the first character in the item) gint32 letter_spacing Required (not null) amount of letter spacing to add in Pango units. May be negative, though too large negative values will give ugly results. Returns: none	Pango.GlyphItem
	split (String *text, gint32 split_index) : Pango.GlyphItem Modifies orig* to cover only the text after split_index, and returns a new item that covers the text before split_index that used to be in orig. Modifies orig to cover only the text after split_index, and returns a new item that covers the text before split_index that used to be in orig. You can think of split_index as the length of the returned item. split_index may not be 0, and it may not be greater than or equal to the length of orig (that is, there must be at least one byte assigned to each item, you can't create a zero-length item). This function is similar in function to pango_item_split() (and uses it internally.) with pango_glyph_item_free(). Parameters: String text Required (not null) text to which positions in orig apply gint32 split_index Required (not null) byte index of position to split item, relative to the start of the item Returns: Pango.GlyphItem the newly allocated item representing text before	Pango.GlyphItem

Events
None

Used by These Methods / Signals / Properties
Class / Namespace	Method / Signal / Properties
Pango.GlyphItemIter Method	init_end (GlyphItem *glyph_item, String text) : gboolean Initializes a PangoGlyphItemIter* structure to point to the last cluster in a glyph item.
Pango.GlyphItemIter Method	init_start (GlyphItem *glyph_item, String text) : gboolean Initializes a PangoGlyphItemIter* structure to point to the first cluster in a glyph item.
Pango.Renderer Method	draw_glyph_item (String *text, GlyphItem glyph_item, gint32 x, gint32 y) : none Draws the glyphs in glyph_item* with the specified PangoRenderer, embedding the text associated with the glyphs in the output if the output format supports it (PDF for example).
PangoCairo Method	PangoCairo.show_glyph_item (Context cr, String *text, GlyphItem glyph_item) : none Draws the glyphs in glyph_item* in the specified cairo context, embedding the text associated with the glyphs in the output if the output format supports it (PDF for example), otherwise it acts similar to pango_cairo_show_glyph_string().
