Boolean
Determines whether iter is on the last line of the layout.
Determines whether iter is on the last line of the layout.

Pango.LayoutIter
Copies a PangLayoutIter.
Copies a PangLayoutIter. be freed with pango_layout_iter_free(), or NULL if

get_baseline
()
:
Number
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).
|
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.
|
Pango.LayoutIter | |
|
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).
|
Pango.LayoutIter | |
|
get_index
()
:
Number
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()).

Pango.LayoutIter | |

get_layout
()
:
Pango.Layout
Gets the layout associated with a PangoLayoutIter.
Gets the layout associated with a PangoLayoutIter.
|
Pango.LayoutIter | |
|
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.
|
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.).
|
Pango.LayoutIter | |
|
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().
|
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.).
|
Pango.LayoutIter | |
|
get_line_yrange
()
:
Object
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).

Pango.LayoutIter | |
|
get_run
()
:
Pango.GlyphItem
Gets the current run.
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. Use the faster pango_layout_iter_get_run_readonly() if you do not plan to modify the contents of the run (glyphs, glyph widths, etc.).
|

get_run_readonly
()
:
Pango.GlyphItem
Gets the current run.
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. This is a faster alternative to pango_layout_iter_get_run(), but the user is not expected to modify the contents of the run (glyphs, glyph widths, etc.).

next_char
()
:
Boolean
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.
|
Pango.LayoutIter | |
|
next_cluster
()
:
Boolean
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.
|
Pango.LayoutIter | |
|
next_line
()
:
Boolean
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.

Pango.LayoutIter | |

next_run
()
:
Boolean
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.
