A step is made up of a name/description, a list of interactive fields (see interactive documentation), a "complete", "pre" and "post" callbacks, an help id, ... The "pre" callback is run first. Its only argument is the actual step hash. Then, if the "name" fiels is a code reference, that callback is run and its actual result is used as the description of the step. At this stage, the interactive layer is used to display the actual step. The "post" callback is only run if the user has steped forward. Alternatively, you can call safe_process() rather than process(). safe_process() will handle for you the "wizcancel" exception while running the wizard. Actually, it should be used everywhere but where the wizard is not the main path (eg "mail alert wizard" in logdrake, ...), ie when you may need to do extra exception managment such as destroying the wizard window and the like. =cut sub new { my ($class, $o) = @_; bless $o, $class; } sub check_rpm { my ($in, $rpms) = @_; foreach my $rpm (@$rpms) { next if $in->do_pkgs->is_installed($rpm); if ($in->ask_okcancel(N("Error"), N("%s is not installed\nClick \"Next\" to install or \"Cancel\" to quit", $rpm))) { $::testing and next; if (!$in->do_pkgs->install($rpm)) { local $::Wizard_finished = 1; $in->ask_okcancel(N("Error"), N("Installation failed")); $in->exit; } } else { $in->exit } } } # sync me with interactive::ask_from_normalize() if needed: my %default_callback = (complete => sub { 0 }); sub process { my ($o, $in) = @_; local $::isWizard = 1; local $::Wizard_title = $o->{name} || $::Wizard_title; local $::Wizard_pix_up = $o->{defaultimage} || $::Wizard_pix_up; #require_root_capability() if $> && !$o->{allow_user} && !$::testing; check_rpm($in, $o->{needed_rpm}) if ref($o->{needed_rpm}); if (defined $o->{init}) { my ($res, $msg) = &{$o->{init}}; if (!$res) { $in->ask_okcancel(N("Error"), $msg); die "wizard failed" if !$::testing; } } my @steps; # steps stack # initial step: my $next = 'welcome'; my $page = $o->{pages}{welcome}; while ($next) { local $::Wizard_no_previous = $page->{no_back}; local $::Wizard_no_cancel = $page->{no_cancel} || $page->{end}; local $::Wizard_finished = $page->{end}; defined $page->{pre} and $page->{pre}($page); die qq(inexistant "$next" wizard step) if is_empty_hash_ref($page); # FIXME or the displaying fails my $data = defined $page->{data} ?
