Tk::IO3pm
High level interface to tk's 'fileevent' mechanism
Usage
my $fh = Tk::IO->new(-linecommand => callback, -childcommand => callback);$fh->exec("command")$fh->wait$fh->kill
Warning
INTERFACES TO THIS MODULE MAY CHANGE AS PERL'S IO EVOLVES AND WITH PORT OF TK4.1
Overview
Tk::IO is now layered on perl's IO::Handle class. Interfaces have changed, and are still evolving.
In theory C methods which enable non-blocking IO as in earlier Tk-b* release(s) are still there. I have not changed them to use perl's additional Configure information, or tested them much.
Assumption is that exec is used to fork a child process and a callback is called each time a complete line arrives up the implied pipe.
"line" should probably be defined in terms of perl's input record separator but is not yet.
The -childcommand callback is called when end-of-file occurs.
$fh->wait can be used to wait for child process while processing other Tk events.
$fh->kill can be used to send signal to child process.
