| 1195 Specifier for a fallback gutter. | |
| 1196 Use `set-specifier' to change this. | |
| 1197 | |
| 1198 The position of this gutter is specified in the function | |
| 1199 `default-gutter-position'. If the corresponding position-specific | |
| 3025 | 1200 gutter (e.g. `top-gutter' if `default-gutter-position' is `top') |
| 428 | 1201 does not specify a gutter in a particular domain (usually a window), |
| 1202 then the value of `default-gutter' in that domain, if any, will be | |
| 1203 used instead. | |
| 1204 | |
| 1205 Note that the gutter at any particular position will not be | |
| 1206 displayed unless its visibility flag is true and its thickness | |
| 1207 \(width or height, depending on orientation) is non-zero. The | |
| 1208 visibility is controlled by the specifiers `top-gutter-visible-p', | |
| 1209 `bottom-gutter-visible-p', `left-gutter-visible-p', and | |
| 1210 `right-gutter-visible-p', and the thickness is controlled by the | |
| 1211 specifiers `top-gutter-height', `bottom-gutter-height', | |
| 1212 `left-gutter-width', and `right-gutter-width'. | |
| 1213 | |
| 1214 Note that one of the four visibility specifiers inherits from | |
| 1215 `default-gutter-visibility' and one of the four thickness | |
| 1216 specifiers inherits from either `default-gutter-width' or | |
| 1217 `default-gutter-height' (depending on orientation), just | |
| 1218 like for the gutter description specifiers (e.g. `top-gutter') | |
| 1219 mentioned above. | |
| 1220 | |
| 1221 Therefore, if you are setting `default-gutter', you should control | |
| 1222 the visibility and thickness using `default-gutter-visible-p', | |
| 1223 `default-gutter-width', and `default-gutter-height', rather than | |
| 1224 using position-specific specifiers. That way, you will get sane | |
| 1225 behavior if the user changes the default gutter position. | |
| 1226 | |
| 442 | 1227 The gutter value should be a string, a property list of strings or |
| 1228 nil. You can attach extents and glyphs to the string and hence display | |
| 1229 glyphs and text in other fonts in the gutter area. If the gutter value | |
| 1230 is a property list then the strings will be concatenated together | |
| 1231 before being displayed. */ ); | |
