I assume you mean that you don't want it to clear after the end of
your window on the current line.  Again, you can fool it:

        a) make ncurses think that the screen does not extend past your
           window's right margin, and
        b) remove the "el" capability (so it will be forced to use blanks
           to fill the line).

See use_env() for the first part.
