Methods / Constructors
Method / Constructor		Defined By
	at_last_line () : gboolean Determines whether iter is on the last line of the layout. Determines whether iter is on the last line of the layout. Returns: gboolean TRUE if iter is on the last line.	Pango.LayoutIter
	copy () : Pango.LayoutIter Copies a PangLayoutIter. Copies a PangLayoutIter. be freed with pango_layout_iter_free(), or NULL if Returns: Pango.LayoutIter the newly allocated PangoLayoutIter, which should	Pango.LayoutIter
	free () : none Frees an iterator that's no longer in use. Frees an iterator that's no longer in use. Returns: none	Pango.LayoutIter
	get_baseline () : gint32 Gets the Y position of the current line's baseline, in layout coordinates (origin at top left of the entire layout). Gets the Y position of the current line's baseline, in layout coordinates (origin at top left of the entire layout). Returns: gint32 baseline of current line.	Pango.LayoutIter
	get_char_extents (Rectangle *logical_rect) : none Gets the extents of the current character, in layout coordinates (origin is the top left of the entire layout). Gets the extents of the current character, in layout coordinates (origin is the top left of the entire layout). Only logical extents can sensibly be obtained for characters; ink extents make sense only down to the level of clusters. Parameters: Pango.Rectangle logical_rect* Required (not null) rectangle to fill with logical extents Returns: none	Pango.LayoutIter
	get_cluster_extents (Rectangle *ink_rect, Rectangle logical_rect) : none Gets the extents of the current cluster, in layout coordinates (origin is the top left of the entire layout). Gets the extents of the current cluster, in layout coordinates (origin is the top left of the entire layout). Parameters: Pango.Rectangle ink_rect* Required (not null) rectangle to fill with ink extents, or NULL Pango.Rectangle logical_rect Required (not null) rectangle to fill with logical extents, or NULL Returns: none	Pango.LayoutIter
	get_index () : gint32 Gets the current byte index. Gets the current byte index. Note that iterating forward by char moves in visual order, not logical order, so indexes may not be sequential. Also, the index may be equal to the length of the text in the layout, if on the NULL run (see pango_layout_iter_get_run()). Returns: gint32 current byte index.	Pango.LayoutIter
	get_layout_extents (Rectangle *ink_rect, Rectangle logical_rect) : none Obtains the extents of the PangoLayout* being iterated over. Obtains the extents of the PangoLayout being iterated over. ink_rect or logical_rect can be NULL if you aren't interested in them. Parameters: Pango.Rectangle ink_rect Required (not null) rectangle to fill with ink extents, or NULL Pango.Rectangle logical_rect Required (not null) rectangle to fill with logical extents, or NULL Returns: none	Pango.LayoutIter
	get_line () : Pango.LayoutLine Gets the current line. Gets the current line. Use the faster pango_layout_iter_get_line_readonly() if you do not plan to modify the contents of the line (glyphs, glyph widths, etc.). Returns: Pango.LayoutLine the current line.	Pango.LayoutIter
	get_line_extents (Rectangle *ink_rect, Rectangle logical_rect) : none Obtains the extents of the current line. Obtains the extents of the current line. ink_rect* or logical_rect can be NULL if you aren't interested in them. Extents are in layout coordinates (origin is the top-left corner of the entire PangoLayout). Thus the extents returned by this function will be the same width/height but not at the same x/y as the extents returned from pango_layout_line_get_extents(). Parameters: Pango.Rectangle ink_rect Required (not null) rectangle to fill with ink extents, or NULL Pango.Rectangle logical_rect Required (not null) rectangle to fill with logical extents, or NULL Returns: none	Pango.LayoutIter
	get_line_readonly () : Pango.LayoutLine Gets the current line for read-only access. Gets the current line for read-only access. This is a faster alternative to pango_layout_iter_get_line(), but the user is not expected to modify the contents of the line (glyphs, glyph widths, etc.). Returns: Pango.LayoutLine the current line, that should not be modified.	Pango.LayoutIter
	get_line_yrange (gint32 *y0_, gint32 y1_) : none Divides the vertical space in the PangoLayout* being iterated over between the lines in the layout, and returns the space belonging to the current line. Divides the vertical space in the PangoLayout being iterated over between the lines in the layout, and returns the space belonging to the current line. A line's range includes the line's logical extents, plus half of the spacing above and below the line, if pango_layout_set_spacing() has been called to set layout spacing. The Y positions are in layout coordinates (origin at top left of the entire layout). Parameters: gint32 y0_ Required (not null) start of line gint32 y1_ Required (not null) end of line Returns: none	Pango.LayoutIter
	get_run_extents (Rectangle *ink_rect, Rectangle logical_rect) : none Gets the extents of the current run in layout coordinates (origin is the top left of the entire layout). Gets the extents of the current run in layout coordinates (origin is the top left of the entire layout). Parameters: Pango.Rectangle ink_rect* Required (not null) rectangle to fill with ink extents, or NULL Pango.Rectangle logical_rect Required (not null) rectangle to fill with logical extents, or NULL Returns: none	Pango.LayoutIter
	next_char () : gboolean Moves iter forward to the next character in visual order. Moves iter forward to the next character in visual order. If iter was already at the end of the layout, returns FALSE. Returns: gboolean whether motion was possible.	Pango.LayoutIter
	next_cluster () : gboolean Moves iter forward to the next cluster in visual order. Moves iter forward to the next cluster in visual order. If iter was already at the end of the layout, returns FALSE. Returns: gboolean whether motion was possible.	Pango.LayoutIter
	next_line () : gboolean Moves iter forward to the start of the next line. Moves iter forward to the start of the next line. If iter is already on the last line, returns FALSE. Returns: gboolean whether motion was possible.	Pango.LayoutIter
	next_run () : gboolean Moves iter forward to the next run in visual order. Moves iter forward to the next run in visual order. If iter was already at the end of the layout, returns FALSE. Returns: gboolean whether motion was possible.	Pango.LayoutIter
