|
|
|
1118
|
|
|
1119 The position of this gutter is specified in the function
|
|
|
1120 `default-gutter-position'. If the corresponding position-specific
|
|
|
1121 gutter (e.g. `top-gutter' if `default-gutter-position' is 'top)
|
|
|
1122 does not specify a gutter in a particular domain (usually a window),
|
|
|
1123 then the value of `default-gutter' in that domain, if any, will be
|
|
|
1124 used instead.
|
|
|
1125
|
|
|
1126 Note that the gutter at any particular position will not be
|
|
|
1127 displayed unless its visibility flag is true and its thickness
|
|
|
1128 \(width or height, depending on orientation) is non-zero. The
|
|
|
1129 visibility is controlled by the specifiers `top-gutter-visible-p',
|
|
|
1130 `bottom-gutter-visible-p', `left-gutter-visible-p', and
|
|
|
1131 `right-gutter-visible-p', and the thickness is controlled by the
|
|
|
1132 specifiers `top-gutter-height', `bottom-gutter-height',
|
|
|
1133 `left-gutter-width', and `right-gutter-width'.
|
|
|
1134
|
|
|
1135 Note that one of the four visibility specifiers inherits from
|
|
|
1136 `default-gutter-visibility' and one of the four thickness
|
|
|
1137 specifiers inherits from either `default-gutter-width' or
|
|
|
1138 `default-gutter-height' (depending on orientation), just
|
|
|
1139 like for the gutter description specifiers (e.g. `top-gutter')
|
|
|
1140 mentioned above.
|
|
|
1141
|
|
|
1142 Therefore, if you are setting `default-gutter', you should control
|
|
|
1143 the visibility and thickness using `default-gutter-visible-p',
|
|
|
1144 `default-gutter-width', and `default-gutter-height', rather than
|
|
|
1145 using position-specific specifiers. That way, you will get sane
|
|
|
1146 behavior if the user changes the default gutter position.
|
|
|
1147
|
|
404
|
1148 The gutter value should be a string, a property list of strings or

1149 nil. You can attach extents and glyphs to the string and hence display
|
|
|
1150 glyphs and text in other fonts in the gutter area. If the gutter value
|
|
|
1151 is a property list then the strings will be concatenated together
