765 Specifier for a fallback gutter.
|

766 Use `set-specifier' to change this.
|
|
|
767
|
|
|
768 The position of this gutter is specified in the function
|
|
|
769 `default-gutter-position'. If the corresponding position-specific
|
|
|
770 gutter (e.g. `top-gutter' if `default-gutter-position' is 'top)
|
|
|
771 does not specify a gutter in a particular domain (usually a window),
|
|
|
772 then the value of `default-gutter' in that domain, if any, will be
|
|
|
773 used instead.
|
|
|
774
|
|
|
775 Note that the gutter at any particular position will not be
|
|
|
776 displayed unless its visibility flag is true and its thickness
|
|
|
777 \(width or height, depending on orientation) is non-zero. The
|
|
|
778 visibility is controlled by the specifiers `top-gutter-visible-p',
|
|
|
779 `bottom-gutter-visible-p', `left-gutter-visible-p', and
|
|
|
780 `right-gutter-visible-p', and the thickness is controlled by the
|
|
|
781 specifiers `top-gutter-height', `bottom-gutter-height',
|
|
|
782 `left-gutter-width', and `right-gutter-width'.
|
|
|
783
|
|
|
784 Note that one of the four visibility specifiers inherits from
|
|
|
785 `default-gutter-visibility' and one of the four thickness
|
|
|
786 specifiers inherits from either `default-gutter-width' or
|
|
|
787 `default-gutter-height' (depending on orientation), just
|
|
|
788 like for the gutter description specifiers (e.g. `top-gutter')
|
|
|
789 mentioned above.
|
|
|
790
|
|
|
791 Therefore, if you are setting `default-gutter', you should control
|
|
|
792 the visibility and thickness using `default-gutter-visible-p',
|
|
|
793 `default-gutter-width', and `default-gutter-height', rather than
|
|
|
794 using position-specific specifiers. That way, you will get sane
|
|
|
795 behavior if the user changes the default gutter position.
|
|
|
796
|
|
|
797 The gutter value should be a string or nil. You can attach extents and
|
|
|
798 glyphs to the string and hence display glyphs and text in other fonts
|
|
|
799 in the gutter area.
