Expand description

The Underline enumeration is used to specify whether text should be underlined, and if so, the type of underlining.

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

no underline should be drawn

Single

a single underline should be drawn

Double

a double underline should be drawn

Low

a single underline should be drawn at a position beneath the ink extents of the text being underlined. This should be used only for underlining single characters, such as for keyboard accelerators. Single should be used for extended portions of text.

Error

an underline indicating an error should be drawn below. The exact style of rendering is up to the Renderer in use, but typical styles include wavy or dotted lines. This underline is typically used to indicate an error such as a possible mispelling; in some cases a contrasting color may automatically be used. This type of underlining is available since Pango 1.4.

SingleLine

Like @PANGO_UNDERLINE_SINGLE, but drawn continuously across multiple runs. This type of underlining is available since Pango 1.46.

DoubleLine

Like @PANGO_UNDERLINE_DOUBLE, but drawn continuously across multiple runs. This type of underlining is available since Pango 1.46.

ErrorLine

Like @PANGO_UNDERLINE_ERROR, but drawn continuously across multiple runs. This type of underlining is available since Pango 1.46.
