Heres a function to get a string from a specific window and return it on ENTER.
// Dynamic String Input (converts INT ASCII to CHAR)
function ncurses_wgetstr($win){
$strlen = 1;
for ($sx=0;$sx<$strlen;$sx++){
$strlen++;
$ch = ncurses_wgetch($win);
if ($ch == 13){
return $str;
break 2;
}
$str .= chr($ch);
}
}
Example:
$ncurse = ncurses_init();
$fullscreen = ncurses_newwin (0,0, 0,0);
ncurses_border(0,0, 0,0, 0,0, 0,0);
ncurses_refresh();
while (1){
$keyPressed = ncurses_wgetstr($fullscreen);
ncurses_wrefresh($fullscreen);
}
By default ncurses_wgetch does not return keypad keys. If you need to use function or arrow keys in a sub window, simply do this first.
ncurses_keypad($win, TRUE);
Something worth noting here; I noticed that with ncurses_wgetch function keys are broken into multiple codes while ncurses_getch returns only one attributed code.
For example, with ncurses_wgetch pressing an up arrow results in three codes 27 91 65 (an ascii escape sequence). The problem is subsequent calls to ncurses_wgetch are required to acquire all three codes. Unfortunately, pressing an “A” key for example would result in only a single code of 65. This makes it hard to trap for both function keys and regular keys.
However, with ncurses_getch an up arrow results in a single attributed code of 259 or the “NCURSES_KEY_UP” key constant. An “A” key is still 65.
