| tab-snip% : class? |
superclass: string-snip% |
An instance of tab-snip% is created automatically when a
tab is inserted into an editor.
Creates a snip for a single tab, though the tab is initially empty.
Normally, a single tab is inserted into a tab-snip% object using the insert method.
The tab’s content is not drawn, through it is used when determining
the size of a single character in editors where tabbing is determined
by the character width (see set-tabs); if the content
is a single tab character (the normal case), then the average
character width of snip’s font is used as the tab’s width.
