Re: Tk Tutorial, Featuring Your Very Own "Perl Sig/OBFU Decoder Ring"

Hi there.

I hope you can help me. There's an extremely simple thing I just can't understand: How can I get the value typed by a user in an Entry widget???

I've tried a very simple program that should take the user entry and put it into a file, so the code snippets would look like this:

#This creates the widget and place it:
my $Entry2 = $mw->Entry( 
                        -relief => "sunken"
                       );
$Entry2->place( -x => 88, -y => 33, -height => 16, -width => 120);

# And I have a button that calls the sub that does the trick:

my $Button3 = $mw->Button( 
                           -text => "Cadastrar",
                           -relief => "raised",
                           -command => \&add
                           );
$Button3->place( -x => 218, -y => 33, -height => 16, -width => 56);

# The above parts works as expected, my problem lies below (notice tha
+t the snippet below is, obviously, after the MainLoop):

sub add
{
    my $name = $Entry2->get(0.1, 'end');
    my $file = "data.dat";

    open(CLIST, "+>>$file");
    flock(CLIST,2);
    print CLIST $name."\n";
    flock(CLIST,8);
    close($file);
}

I just can't capture the Entry value. Please help me.

Thanks in advance,
