note 40198 added to ref.ncurses

What if you want to draw a new window and after removing it, showing the pervious screen again? Unfortunately, there is no such a thing in php/ncurses as there is in original curses library (touchwin if I'm not mistaken - It has been a long time!). However, you can do this by a simple trick! You can dump the screen to a temp file and then restore it back again! Take a look at this function: # Function: show_a_win() # - Displays a small window and writes something in it. # - waits for a key # - shows the pervious screen again function show_a_win() { # Dump the current screen into a temp file: $tmpfile = tempnam("/tmp", "dump."); # Create a new window. $newwin = ncurses_newwin(4, 60, 10, 10); # Write something and then refresh it ncurses_mvwaddstr($newwin, 1, 1, "This is a test."); ncurses_wrefresh($newwin); # Wait for a key ncurses_wgetch($newwin); ncurses_delwin($newwin); /* delete the window */ /* Restore the screen the same way it was before entering * into the function: */ ncurses_scr_restore($tmpfile); unlink($tmpfile); /* Remove temp file */ } ---- Manual Page -- http://www.php.net/manual/en/ref.ncurses.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+40198 Delete -- http://master.php.net/manage/user-notes.php?action=delete+40198&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+40198&report=yes Search -- http://master.php.net/manage/user-notes.php
