=head1 NAME

UI::Dialog::Backend::KDialog

=head1 SYNOPSIS

  use UI::Dialog::Backend::KDialog;
  my $d = new UI::Dialog::Backend::KDialog ( backtitle => 'Demo',
                                             title => 'Default' );

  $d->msgbox( title => 'Welcome!', text => 'Welcome one and all!' );

=head1 ABSTRACT

UI::Dialog::Backend::KDialog is the UI::Dialog backend for the KDE dialog
variant. While this module is used through UI::Dialog or any other loader
module only the compatible methods are ever accessible. However, when using
this module directly in your application (as in the SYNOPSIS example) you are
given access to all the options and features of the real kdialog(1) application.

=head1 DESCRIPTION

Although this dialog variant doesn't have any progress meters, it does have the
benefits of many different file/uri/directory widgets. It's a shame that this is
the only dialog variant for KDE.
