| 1233 Specifier for a fallback gutter. | |
| 1234 Use `set-specifier' to change this. | |
| 1235 | |
| 1236 The position of this gutter is specified in the function | |
| 1237 `default-gutter-position'. If the corresponding position-specific | |
| 3025 | 1238 gutter (e.g. `top-gutter' if `default-gutter-position' is `top') |
| 428 | 1239 does not specify a gutter in a particular domain (usually a window), |
| 1240 then the value of `default-gutter' in that domain, if any, will be | |
| 1241 used instead. | |
| 1242 | |
| 1243 Note that the gutter at any particular position will not be | |
| 1244 displayed unless its visibility flag is true and its thickness | |
| 1245 \(width or height, depending on orientation) is non-zero. The | |
| 1246 visibility is controlled by the specifiers `top-gutter-visible-p', | |
| 1247 `bottom-gutter-visible-p', `left-gutter-visible-p', and | |
| 1248 `right-gutter-visible-p', and the thickness is controlled by the | |
| 1249 specifiers `top-gutter-height', `bottom-gutter-height', | |
| 1250 `left-gutter-width', and `right-gutter-width'. | |
| 1251 | |
| 1252 Note that one of the four visibility specifiers inherits from | |
| 1253 `default-gutter-visibility' and one of the four thickness | |
| 1254 specifiers inherits from either `default-gutter-width' or | |
| 1255 `default-gutter-height' (depending on orientation), just | |
| 1256 like for the gutter description specifiers (e.g. `top-gutter') | |
| 1257 mentioned above. | |
| 1258 | |
| 1259 Therefore, if you are setting `default-gutter', you should control | |
| 1260 the visibility and thickness using `default-gutter-visible-p', | |
| 1261 `default-gutter-width', and `default-gutter-height', rather than | |
| 1262 using position-specific specifiers. That way, you will get sane | |
| 1263 behavior if the user changes the default gutter position. | |
| 1264 | |
| 442 | 1265 The gutter value should be a string, a property list of strings or |
| 1266 nil. You can attach extents and glyphs to the string and hence display | |
| 1267 glyphs and text in other fonts in the gutter area. If the gutter value | |
| 1268 is a property list then the strings will be concatenated together | |
