~ Abstract

This TIP allows Tk widgets which have a configurable ''-state'' option
to accept ''enabled'' as a synonym for ''normal''.

~ Rationale

Tk widgets which have a configurable ''-state'' option have (at a
minimum) ''normal'' and ''disabled'' states.  In common usage,
however, the antonym of ''disabled'' is ''enabled'', not ''normal''.

Even experienced Tcl/Tk programmers sometimes forget, though they
usually won't come out and admit it explicitly.  (Cf.
http://groups.google.com/groups?th=66e286d7efc3bbb6)

~ Proposed Changes

Modify all Tk widgets which have a configurable ''-state'' option to
accept ''enabled'' as a synonym for ''normal''.  The value returned by
a widget's ''cget'' method would continue to be ''normal''.  The
appropriate man pages and test suite will be updated to document and
test the use of ''enabled'' as a synonym.

|% $w configure -state enabled
|% puts [$w cget -state]
|normal

~ Implementation

A reference implementation will be provided shortly.
