Please provide a complete but short example script.

sorry.....
initialize, create window, set color
// the window was create with 20 lines and 60 colums...so
//$nr_linhas=20; $nr_colunas=60;

ncurses_wborder($win, 0,0,0,0,0,0,0,0);
$l = 1;
while($l < $nr_linhas - 1) {
$c = 1;
   ncurses_wmove($win, $l, 1);
   while($c++ < $nr_colunas - 1) {
      ncurses_waddch($win, 65);
      //ncurses_wrefresh($win); // only here attribute is set
   }
   $l++;
   // using wrefresh here nothing change
}
// using wrefresh here nothing change

using waddstr seems the same thing.
if you trie to use waddch once the attribute is set ok.
but using routine to put more than 13 charachters its necessery use wrefresh (after 13 characters).
