PangoUnderline
The PangoUnderline enumeration is used to specify whether text should be underlined, and if so, the type of underlining.
Value | Symbolic name | Description |
| 0 | Pango::UNDERLINE_NONE | no underline should be drawn. |
| 1 | Pango::UNDERLINE_SINGLE | a single underline should be drawn. |
| 2 | Pango::UNDERLINE_DOUBLE | a double underline should be drawn. |
| 3 | Pango::UNDERLINE_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. Pango::UNDERLINE_SINGLE should be used for extended portions of text. |
| 4 | Pango::UNDERLINE_ERROR | A wavy underline should be drawn below. This underline is typically used to indicate an error such as a possilble mispelling; in some cases an contrasting color may automatically be used. This type of underlining is available since Pango 1.4. |
