| 1234 Specifier for a fallback gutter. | |
| 1235 Use `set-specifier' to change this. | |
| 1236 | |
| 1237 The position of this gutter is specified in the function | |
| 1238 `default-gutter-position'. If the corresponding position-specific | |
| 3025 | 1239 gutter (e.g. `top-gutter' if `default-gutter-position' is `top') |
| 428 | 1240 does not specify a gutter in a particular domain (usually a window), |
| 1241 then the value of `default-gutter' in that domain, if any, will be | |
| 1242 used instead. | |
| 1243 | |
| 1244 Note that the gutter at any particular position will not be | |
| 1245 displayed unless its visibility flag is true and its thickness | |
| 1246 \(width or height, depending on orientation) is non-zero. The | |
| 1247 visibility is controlled by the specifiers `top-gutter-visible-p', | |
| 1248 `bottom-gutter-visible-p', `left-gutter-visible-p', and | |
| 1249 `right-gutter-visible-p', and the thickness is controlled by the | |
| 1250 specifiers `top-gutter-height', `bottom-gutter-height', | |
| 1251 `left-gutter-width', and `right-gutter-width'. | |
| 1252 | |
| 1253 Note that one of the four visibility specifiers inherits from | |
| 1254 `default-gutter-visibility' and one of the four thickness | |
| 1255 specifiers inherits from either `default-gutter-width' or | |
| 1256 `default-gutter-height' (depending on orientation), just | |
| 1257 like for the gutter description specifiers (e.g. `top-gutter') | |
| 1258 mentioned above. | |
| 1259 | |
| 1260 Therefore, if you are setting `default-gutter', you should control | |
| 1261 the visibility and thickness using `default-gutter-visible-p', | |
| 1262 `default-gutter-width', and `default-gutter-height', rather than | |
| 1263 using position-specific specifiers. That way, you will get sane | |
| 1264 behavior if the user changes the default gutter position. | |
| 1265 | |
| 442 | 1266 The gutter value should be a string, a property list of strings or |
| 1267 nil. You can attach extents and glyphs to the string and hence display | |
| 1268 glyphs and text in other fonts in the gutter area. If the gutter value | |
