Digg  ncurses_wrefresh
Refresh window on terminal screen
(PHP 4 >= 4.2.0, PHP 5, PECL ncurses:1.0.0)
Code Examples / Notes » ncurses_wrefreshphp
Keep in mind, you need to do a ncurses_refresh before any window drawing options to display the window correctly. for example ncurses_wclear($window); ncurses_wborder($window, 0, 0, 0, 0, 0, 0, 0, 0); ncurses_wrefresh($window); won't work correctly the first time though the loop (not sure why), but throw on a ncruses_refresh at the top and it displays correctly joeldegan
Here is a functional example of drawing dynamic windows and refreshing them using ncurses_wrefresh. This draws the main window, borders it, creates a small window borders it, creates a lower window and borders it as well. it also shows an example of doing a little backgrounding.. <?php /* the window will look somewhat like this... +--------------------------------------+ |+---+ | || | | |+---+ | | | |+------------------------------------+| || || |+------------------------------------+| +--------------------------------------+ */ $n=0; $a = ncurses_init(); ncurses_border(0,0, 0,0, 0,0, 0,0); $z = ncurses_newwin ( 15, 15, 10, 10); if(ncurses_has_colors()){ ncurses_start_color(); ncurses_init_pair(1,NCURSES_COLOR_RED,NCURSES_COLOR_BLACK); ncurses_init_pair(2,NCURSES_COLOR_BLUE,NCURSES_COLOR_BLACK); ncurses_init_pair(3,NCURSES_COLOR_YELLOW,NCURSES_COLOR_BLACK); ncurses_init_pair(4,NCURSES_COLOR_BLUE,NCURSES_COLOR_BLACK); ncurses_init_pair(5,NCURSES_COLOR_MAGENTA,NCURSES_COLOR_BLACK); ncurses_init_pair(6,NCURSES_COLOR_CYAN,NCURSES_COLOR_BLACK); ncurses_init_pair(7,NCURSES_COLOR_WHITE,NCURSES_COLOR_BLACK); }//fi while(1){ for ($x=1; $x<80; $x++) { for ($y=1; $y<24; $y++) { $n++; ncurses_move($y,$x); ncurses_addch($n+64); ncurses_color_set($n%8); if($n>26)$n=0; }//rof }//rof // border the main window ncurses_border(0,0, 0,0, 0,0, 0,0); ncurses_refresh(); // create a new little window and border it. $z = ncurses_newwin ( 10, 10, 2, 2); ncurses_wborder($z,0,0, 0,0, 0,0, 0,0); // undocumented function, border the window ncurses_wrefresh($z); // show it // get our maximum y and x values $current = getmaxxy(); $lines = $current[1]; $cols = $current[0]; // create a lower window which is dynamically sized... $c = ncurses_newwin (10, $cols-4, $lines-11, 2); ncurses_wborder($c,0,0, 0,0, 0,0, 0,0); // border it ncurses_wrefresh($c); // show it ncurses_getch(); // wait for user to press key ncurses_clear();// clear and then redraw.. }//wend function getmaxxy(){ $rez = `/usr/X11R6/bin/resize`; $rez = explode("\n",$rez); while(list($key,$val)=each($rez)){ $a=explode("=",$val); if(trim($a[0])=="COLUMNS"){ $COLUMNS = $a[1]; } if(trim($a[0])=="LINES"){ $LINES = $a[1]; } }// $retval[0]=$COLUMNS; $retval[1]=$LINES; return $retval; } ?> |
