What screen are you trying to clear?
If you are trying to clear a tty (e.g. xterm) screen then try either of the following within your script:
system "clear"; or print `clear`;(where the choice between these two depends on the rest of the script: the first is fast - but proceeds via fork and may not occur at exactly the time that you want it to in the script).
David and Rachel Weintraub <davidw@cnj.digex.net> recommend using the old termcap.pl p4 library. You might also consider the perl 5 equivalents: Term.pm (especially the Term::Control module), Curses.pm, Perlmenu.pm, PV.
If you are trying to eliminate a TopLevel or a MainWindow then try:
$main -> destroy;If you would rather not destroy then try:
$main->withdraw; # remove $main->deiconify; # put backIf $w is a sub-window (sub-widget) then
$w->pack('forget'); # remove if packed (newer Tk-b9.01++) $w->packForget; # remove if packed (older versions) $w->pack(...); # put backThere are also ways to call low level C-ish versions:
$w->UnmapWindow;but that is for special purposed only....
If you are trying to erase an $item on a Canvas then try:
delete($item);
