NAME¶

 UI::Dialog::Backend::Whiptail - Backend for the Whiptail dialog variant

SYNOPSIS¶

  use UI::Dialog::Backend::Whiptail;
  my $d = new UI::Dialog::Backend::Whiptail ( backtitle => 'Demo',
                                              title => 'Default' );
  $d->msgbox( title => 'Welcome!', text => 'Welcome one and all!' );

ABSTRACT¶

UI::Dialog::Backend::Whiptail is the UI::Dialog backend for the Whiptail 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 whiptail(1) application.

DESCRIPTION¶

This dialog variant is the staple of the Debian console apt/dpkg interface. There isn't very much interesting about this particular backend. This is very much a basic dialog variant in comparison to things like Xdialog and cDialog.

EXPORT¶
