Silly question of the day:

I am writing a relatively simple perl program to show a graphical menu of source, exclusions, and destination directory. When the user clicks the Sync button, it copies everything from source to destination.

I would like to display a progress bar for the process . . perhaps refreshing itself each time it starts a new directory. As it stands I don't have a bloody clue how to do this (I am assuming the use of Tk::ProgressBar).

Here is the relevant section where the code should go:

    foreach my $dir (@SOURCE) {
        next if ($dir eq any(@exclusion_list));
        my $mw = MainWindow->new; # Don't use existing window.
        my $cmd = "cp -a $home_value\/$dir $storage";
        while (system($cmd)) {
         my $progress = $mw->ProgressBar(
        -width => 200,
        -height => 20,
        -from => 0,
        -to => 100,
        -blocks => 10,
        -colors => [0, 'green', 50, 'yellow' , 80, 'red'],
        -variable => \$percent_done
    );
    }
}

Obviously this is rudimentary and wrong. i.e I know I somehow need feedback from the system call, and I need to use it to feed the $percent_done, and I also need to know how to "refresh" when the next directory is started. Can anyone provide me with a pointer in the right direction?


What does this little button do . .<Click>; "USER HAS SIGNED OFF FOR THE DAY"
