Description

 
Synopsis

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.

Constructors

AlignmentCenter

Center the line within the available space

AlignmentRight

Put all available space on the left

BidiType

data BidiType Source #

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

Constructors

AnotherBidiType Int

Catch-all for unknown values

CoverageLevel

data CoverageLevel Source #

Used to indicate how well a font can represent a particular Unicode character point for a particular script.

Constructors

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

Direction

data Direction Source #

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.

Constructors

DirectionLtr

A strong left-to-right direction

DirectionRtl

A strong right-to-left direction

DirectionTtbLtr

Deprecated value; treated the same as DirectionRtl.

DirectionTtbRtl

Deprecated value; treated the same as DirectionLtr

DirectionWeakLtr

A weak left-to-right direction

DirectionWeakRtl

A weak right-to-left direction

DirectionNeutral

No direction specified

AnotherDirection Int

Catch-all for unknown values

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.

Constructors

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

Gravity

data Gravity Source #

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

Constructors

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

Constructors

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

RenderPart

data RenderPart Source #

RenderPart defines different items to render for such purposes as setting colors.

Since: 1.8

Constructors

RenderPartForeground

RenderPartBackground

RenderPartUnderline

underlines

RenderPartStrikethrough

strikethrough lines

Catch-all for unknown values

Script

data Script Source #

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 url="http://www.unicode.org/reports/tr24/">Unicode Standard Annex 24: Script names</ulink>.
