after-delete in color:text-mixin
Called after a given range is deleted from the editor
(and after the display is refreshed; use
on-delete and
begin-edit-sequence to avoid extra refreshes when
after-delete modifies the editor).
See also
can-delete? and
on-edit-sequence.
No internals locks are set when this method is called.
( -> voidsend a-color:text-mixin after-delete)
The start argument specifies the starting position of the
deleted range. The len argument specifies number of deleted
items (so start + len is the ending position of the
deleted range).
