|

1092 Use `set-specifier' to change this.
|
|
1093
|
|
1094 The position of this gutter is specified in the function
|
|
1095 `default-gutter-position'. If the corresponding position-specific
|
|
1096 gutter (e.g. `top-gutter' if `default-gutter-position' is 'top)
|
|
1097 does not specify a gutter in a particular domain (usually a window),
|
|
1098 then the value of `default-gutter' in that domain, if any, will be
|
|
1099 used instead.
|
|
1100
|
|
1101 Note that the gutter at any particular position will not be
|
|
1102 displayed unless its visibility flag is true and its thickness
|
|
1103 \(width or height, depending on orientation) is non-zero. The
|
|
1104 visibility is controlled by the specifiers `top-gutter-visible-p',
|
|
1105 `bottom-gutter-visible-p', `left-gutter-visible-p', and
|
|
1106 `right-gutter-visible-p', and the thickness is controlled by the
|
|
1107 specifiers `top-gutter-height', `bottom-gutter-height',
|
|
1108 `left-gutter-width', and `right-gutter-width'.
|
|
1109
|
|
1110 Note that one of the four visibility specifiers inherits from
|
|
1111 `default-gutter-visibility' and one of the four thickness
|
|
1112 specifiers inherits from either `default-gutter-width' or
|
|
1113 `default-gutter-height' (depending on orientation), just
|
|
1114 like for the gutter description specifiers (e.g. `top-gutter')
|
|
1115 mentioned above.
|
|
1116
|
|
1117 Therefore, if you are setting `default-gutter', you should control
|
|
1118 the visibility and thickness using `default-gutter-visible-p',
|
|
1119 `default-gutter-width', and `default-gutter-height', rather than
|
|
1120 using position-specific specifiers. That way, you will get sane
|
|
1121 behavior if the user changes the default gutter position.
|
|
1122
|
404
|
1123 The gutter value should be a string, a property list of strings or
|
|
1124 nil. You can attach extents and glyphs to the string and hence display
|
|
1125 glyphs and text in other fonts in the gutter area. If the gutter value
