Friday is "free pizza day" at my place. Of course this script will only get you "part way there", about as worthy as a $5.00 pizza. :-) You will need to add scrolling(hint: add a frame first, then add a Scrolled Text to the frame), and you will need to devise bindings to return the line number selected. But I will leave that to you, what do you expect for $5.00?, you won't get a full load of toppings.
#!/usr/bin/perl
use Tk;
use Tk::DialogBox;
my $file = shift || $0;
my $mw = MainWindow->new;
my $dialog = $mw->DialogBox(
-buttons => [qw/Ok Cancel/],
-title => "Enter New Value"
);
my $dialogT = $dialog->add("Text");
$dialogT->pack(qw/-padx 10 -pady 10/);
my $button = $mw->Button(
-text => "Get new value...",
-command => [ \&getNewValue, $file ]
)->pack(qw/-side left -padx 10/);
MainLoop;
sub getNewValue {
my $filein = shift;
open(FH,"<$filein") or warn "$!\n";
my $text = do {local $/; <FH>};
$dialogT->insert('end',$text);
## Determine whether or not the user hit "Ok"
my $button = $dialog->Show();
if ( $button eq "Ok" ) {
my $letters = $dialogT->get( '1.0', 'end' );
print "$letters was submitted\n";
}
}
__END__
I'm not really a human, but I play one on earth.
