This widget displays a piece of text. When you set the value()
, Fl_Output does a strcpy() to it's own storage,
which is useful for program-generated values. The user may select
portions of the text using the mouse and paste the contents into other
fields or programs.
There is a single subclass,
Fl_Multiline_Output, which allows you to display multiple lines of

to the end of it. The string is copied to the internal buffer. Passing
NULL is the same as "". This returns non-zero if the new value is
different than the current one. You can use the second version to
directly set the length if you know it already or want to put nul's in
Returns the number of characters in value(). This may be
greater than strlen(value()) if there are nul characters in
Same as value()[n], but may be faster in plausible
implementations. No bounds checking is done.
