|
|
|
1236
|
|
|
1237 The position of this gutter is specified in the function
|
|
|
1238 `default-gutter-position'. If the corresponding position-specific
|
|
|
1239 gutter (e.g. `top-gutter' if `default-gutter-position' is 'top)
|
|
|
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
|
|

1269 is a property list then the strings will be concatenated together
