Enumerations
Alignment
A Alignment
describes how to align the lines of a Layout
within the
available space. If the Layout
is set to justify
using layoutSetJustify
, this only has effect for partial lines.
AlignmentLeft | Put all available space on the right |
AlignmentCenter | Center the line within the available space |
AlignmentRight | Put all available space on the left |
AnotherAlignment Int | Catch-all for unknown values |

AttrType
The AttrType
distinguishes between different types of attributes. Along with the
predefined values, it is possible to allocate additional values
for custom attributes using attrTypeRegister
. The predefined
values are given below. The type of structure used to store the
attribute is listed in parentheses after the description.

BidiType
Deprecated: (Since version 1.44)Use fribidi for this information
The BidiType
type represents the bidirectional character
type of a Unicode character as specified by the
<ulink url="http://www.unicode.org/reports/tr9/">Unicode bidirectional algorithm</ulink>.
Since: 1.22
BidiTypeL | Left-to-Right |
BidiTypeLre | Left-to-Right Embedding |

CoverageLevel
data CoverageLevel Source #
Used to indicate how well a font can represent a particular Unicode character point for a particular script.
CoverageLevelNone | The character is not representable with the font. |
CoverageLevelFallback | The character is represented in a way that may be comprehensible but is not the correct graphical form. For instance, a Hangul character represented as a a sequence of Jamos, or a Latin transliteration of a Cyrillic word. |
CoverageLevelApproximate | The character is represented as basically the correct graphical form, but with a stylistic variant inappropriate for the current script. |
CoverageLevelExact | The character is represented as the correct graphical form. |
AnotherCoverageLevel Int | Catch-all for unknown values |
Instances
Direction
The Direction
type represents a direction in the
Unicode bidirectional algorithm; not every value in this
enumeration makes sense for every usage of Direction
;
for example, the return value of unicharDirection
and findBaseDir
cannot be DirectionWeakLtr
or DirectionWeakRtl
, since every character is either
neutral or has a strong direction; on the other hand
DirectionNeutral
doesn't make sense to pass
to itemizeWithBaseDir
.
The DirectionTtbLtr
, DirectionTtbRtl
values come from an earlier interpretation of this
enumeration as the writing direction of a block of
text and are no longer used; See Gravity
for how
vertical text is handled in Pango.
If you are interested in text direction, you should really use fribidi directly. PangoDirection is only retained because it is used in some public apis.
DirectionLtr | A strong left-to-right direction |
DirectionRtl | A strong right-to-left direction |
DirectionTtbLtr | Deprecated value; treated the
same as |
DirectionTtbRtl | Deprecated value; treated the
same as |
DirectionWeakLtr | A weak left-to-right direction |
DirectionWeakRtl | A weak right-to-left direction |
DirectionNeutral | No direction specified |

EllipsizeMode
data EllipsizeMode Source #
The EllipsizeMode
type describes what sort of (if any)
ellipsization should be applied to a line of text. In
the ellipsization process characters are removed from the
text in order to make it fit to a given width and replaced
with an ellipsis.
EllipsizeModeNone | No ellipsization |
EllipsizeModeStart | Omit characters at the start of the text |
EllipsizeModeMiddle | Omit characters in the middle of the text |
EllipsizeModeEnd | Omit characters at the end of the text |
AnotherEllipsizeMode Int | Catch-all for unknown values |
Instances
Gravity
The Gravity
type represents the orientation of glyphs in a segment
of text. This is useful when rendering vertical text layouts. In
those situations, the layout is rotated using a non-identity PangoMatrix,
and then glyph orientation is controlled using Gravity
.
Not every value in this enumeration makes sense for every usage of
Gravity
; for example, GravityAuto
only can be passed to
contextSetBaseGravity
and can only be returned by
contextGetBaseGravity
.
See also: GravityHint
Since: 1.16
GravitySouth | Glyphs stand upright (default) |
GravityEast | Glyphs are rotated 90 degrees clockwise |
GravityNorth | Glyphs are upside-down |
GravityWest | Glyphs are rotated 90 degrees counter-clockwise |
GravityAuto | Gravity is resolved from the context matrix |

GravityHint
data GravityHint Source #
The GravityHint
defines how horizontal scripts should behave in a
vertical context. That is, English excerpt in a vertical paragraph for
example.
See Gravity
.
Since: 1.16
GravityHintNatural | scripts will take their natural gravity based on the base gravity and the script. This is the default. |
GravityHintStrong | always use the base gravity set, regardless of the script. |
GravityHintLine | for scripts not in their natural direction (eg. Latin in East gravity), choose per-script gravity such that every script respects the line progression. This means, Latin and Arabic will take opposite gravities and both flow top-to-bottom for example. |
AnotherGravityHint Int | Catch-all for unknown values |
Instances
RenderPart
data RenderPart Source #
RenderPart
defines different items to render for such
purposes as setting colors.
Since: 1.8
RenderPartForeground | the text itself |
RenderPartBackground | the area behind the text |
RenderPartUnderline | underlines |
RenderPartStrikethrough | strikethrough lines |
AnotherRenderPart Int | Catch-all for unknown values |
Instances
Script
The Script
enumeration identifies different writing
systems. The values correspond to the names as defined in the
Unicode standard.
Note that new types may be added in the future. Applications should be ready
to handle unknown values. This enumeration is interchangeable with
UnicodeScript
. See <ulink

24
