 ##  from previous posts ###############
I have plenty of examples for Gtk2 windows, and capturing
keyboard events, but I hav'nt found anything for Glib alone,
for use in commandline loops.

I can put
Glib::IO->add_watch (fileno 'STDIN', [qw/in/], \&watch_callback);

and watch what is input on STDIN, but is that the best way?
Thanks,

Re: Does the Glib mainloop have the ability to capture keypresses?

I took that approach in gish, where i faked out the Tk portion of  
Readline.

But it is important that you set up STDIN properly to give you all  
the characters pressed, instead of using line-buffering.  Readline  
does that for you...  in your own app, you'll have to use the termios 
+ 
stuff from the POSIX module.

I came up with 2 different versions. The first will trigger the callba
+ck
on an enter press, to take whole line commands.

#!/usr/bin/perl
use warnings;
use strict;
use Glib;
use Glib qw/TRUE FALSE/;

use FileHandle;
#accepts enter to provide input
my $fh_in = FileHandle->new();
$fh_in = *STDIN{IO};                                                  
+                

my $main_loop = Glib::MainLoop->new;

Glib::IO->add_watch (fileno 'STDIN', [qw/in/], \&watch_callback);

$main_loop->run;
######################################
sub watch_callback {
  while (<$fh_in>) {                                                  
+                      
    my $line = $_;
    if (defined($line) and $line ne ''){
          print $line;
    }
  }
return 0;
}
__END__

The above waits for you to type, then press enter, to get a whole line
+.
Without the FileHandle module, you could still send commands to STDIN,
but you needed a Control-d to send it. It would however, allow multi-l
+ine
input.

This one will capture just a key-press, which you can process.

#!/usr/bin/perl
use warnings;
use strict;
use Glib;
use Glib qw/TRUE FALSE/;

use Term::ReadKey;
$|++;
ReadMode('cbreak');

my $main_loop = Glib::MainLoop->new;

Glib::Idle->add(
        sub{
            my $char;
            if (defined ($char = ReadKey(0)) ) {
            print "$char->", ord($char),"\n";    
            #process key presses here
            }
          return TRUE; #keep this going
          });
       
$main_loop->run;
ReadMode('normal'); # restore normal tty settings
__END__
