+/**
+ This is the FLTK text input widget. It displays a single line
+ of text and lets the user edit it. Normally it is drawn with an
+ inset box and a white background. The text may contain any
+ characters, and will correctly display any UTF text, using
+ ^X notation for unprintable control characters. It assumes the
+ font can draw any characters of the used scripts, which is true
+ for standard fonts under MSWindows and Mac OS X.
+ Characters can be input using the keyboard or the character palette/map.
+ Character composition is done using dead keys and/or a compose
+ key as defined by the operating system.
