Hi group
'zenity' is a piece of comand line utility to provide GUI (Gtk)
for the basic input or static output operations on a script.
Like dialog, but in gtk.
I have found strange unexpected behavior in the progress option.
The page documenting its use is here:
https://help.gnome.org/users/zenity/3.8/progress.html.es
Here's a piece that don't works well, as if $|=1 does not
have effect. Another bug it's related with the use of $?
$|=1;
my @list = 0..10; # warning, do not increase!
progress ( "Se ha completado el 100 %", "# Progreso:" , \@list );
sub progress {
my ($title, $text, $percentage) = @_;
open ZEN, "|-", "zenity --progress title=\"$title\" text=\"$text\"
percentage=0" or
die "Cannot open zen";
for my $i (@$percentage) {
print ZEN "$i\n";
if ( $? == -1 ) {
error( "¡Cancelado!" );
exit -1;
}
sleep 1;
}
close ZEN;
}
sub error {
my ($text) = @_;
`zenity --error text="$text"`;
}
Note that in the help page there is a working bash example, which works
well.
Thanks in advance
