MatchEditor - StringEditor with string completion


#include <InterViews/compeditor.h>


CompletionEditor is a StringEditor subclass with the added ability to complete the current contents of the edit buffer against a specified set of strings. A CompletionEditor is often useful when a user must specify a selection from a large set of well-known strings--the user need only type the first few characters of the string; he types the completion character to fill out the remainder.

When the user types the completion character, CompletionEditor checks the current string against the list of possible completions. If the current string is a prefix of one or more completion strings, characters are appended so that the edit string contains the longest common prefix; if the current string does not match any completion string, trailing characters are removed until the string matches at least one completion. In any case, if there is more than one possible completion of a string, CompletionEditor rings the workstation bell.


Create a new CompletionEditor object. The ButtonState, sample string, and termination string are passed to the StringEditor constructor.
Specify the list of completion strings and the completion character. The initial completion list is empty, and the completion character defaults to a space. CompletionEditor does not copy the strings in the list.
