|
|

1191
|

1192 The position of this gutter is specified in the function

|

1193 `default-gutter-position'. If the corresponding position-specific
|
|
|
1194 gutter (e.g. `top-gutter' if `default-gutter-position' is 'top)
|
|
|
1195 does not specify a gutter in a particular domain (usually a window),
|
|
|
1196 then the value of `default-gutter' in that domain, if any, will be
|
|
|
1197 used instead.
|
|
|
1198
|
|
|
1199 Note that the gutter at any particular position will not be
|
|
|
1200 displayed unless its visibility flag is true and its thickness
|
|
|
1201 \(width or height, depending on orientation) is non-zero. The
|
|
|
1202 visibility is controlled by the specifiers `top-gutter-visible-p',
|
|
|
1203 `bottom-gutter-visible-p', `left-gutter-visible-p', and
|
|
|
1204 `right-gutter-visible-p', and the thickness is controlled by the
|
|
|
1205 specifiers `top-gutter-height', `bottom-gutter-height',
|
|
|
1206 `left-gutter-width', and `right-gutter-width'.
|
|
|
1207
|
|
|
1208 Note that one of the four visibility specifiers inherits from
|
|
|
1209 `default-gutter-visibility' and one of the four thickness
|
|
|
1210 specifiers inherits from either `default-gutter-width' or
|
|

1211 `default-gutter-height' (depending on orientation), just
|
|
|
1212 like for the gutter description specifiers (e.g. `top-gutter')
|
|
|
1213 mentioned above.
|
|
|
1214
|
|
|
1215 Therefore, if you are setting `default-gutter', you should control
|
|
|
1216 the visibility and thickness using `default-gutter-visible-p',
|
|
|
1217 `default-gutter-width', and `default-gutter-height', rather than
|
|
|
1218 using position-specific specifiers. That way, you will get sane
|
|
|
1219 behavior if the user changes the default gutter position.
|
|
|
1220
|
|
442
|
1221 The gutter value should be a string, a property list of strings or

|
|
1223 glyphs and text in other fonts in the gutter area. If the gutter value

1224 is a property list then the strings will be concatenated together
