PgLayoutIter

atLastLine bool atLastLine(): Determines whether @iter is on the last line of the layout.
copy PgLayoutIter copy(): Copies a #PangoLayoutIter.
free void free(): Frees an iterator that's no longer in use.
getBaseline int getBaseline(): Gets the Y position of the current line's baseline, in layout coordinates (origin at top left of the entire layout).
getCharExtents void getCharExtents(PangoRectangle logicalRect): 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.
getClusterExtents void getClusterExtents(PangoRectangle inkRect, PangoRectangle logicalRect): Gets the extents of the current cluster, in layout coordinates (origin is the top left of the entire layout).
getIndex int getIndex(): 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()).
getLayout PgLayout getLayout(): Gets the layout associated with a #PangoLayoutIter.
getLayoutExtents void getLayoutExtents(PangoRectangle inkRect, PangoRectangle logicalRect): Obtains the extents of the #PangoLayout being iterated over. @ink_rect or @logical_rect can be %NULL if you aren't interested in them.
getLine PgLayoutLine getLine(): Gets the current line.
getLineExtents void getLineExtents(PangoRectangle inkRect, PangoRectangle logicalRect): 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().
getLineReadonly PgLayoutLine getLineReadonly(): Gets the current line for read-only access.
getLineYrange void getLineYrange(int y0, int y1): 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).
getPgLayoutIterStruct PangoLayoutIter* getPgLayoutIterStruct(bool transferOwnership): Get the main Gtk struct
getRun PangoLayoutRun* getRun(): Gets the current run. When iterating by run, at the end of each line, there's a position with a %NULL run, so this function can return %NULL. The %NULL run at the end of each line ensures that all lines have at least one run, even lines consisting of only a newline.
getRunExtents void getRunExtents(PangoRectangle inkRect, PangoRectangle logicalRect): Gets the extents of the current run in layout coordinates (origin is the top left of the entire layout).
getRunReadonly PangoLayoutRun* getRunReadonly(): Gets the current run. When iterating by run, at the end of each line, there's a position with a %NULL run, so this function can return %NULL. The %NULL run at the end of each line ensures that all lines have at least one run, even lines consisting of only a newline.
getStruct void* getStruct(): the main Gtk struct as a void*
nextChar bool nextChar(): Moves @iter forward to the next character in visual order. If @iter was already at the end of the layout, returns %FALSE.
nextCluster bool nextCluster(): Moves @iter forward to the next cluster in visual order. If @iter was already at the end of the layout, returns %FALSE.
nextLine bool nextLine(): Moves @iter forward to the start of the next line. If @iter is already on the last line, returns %FALSE.
nextRun bool nextRun(): Moves @iter forward to the next run in visual order. If @iter was already at the end of the layout, returns %FALSE.
