NAME

UI::Dialog::Backend::Zenity

SYNOPSIS

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

ABSTRACT

Zenity is the speedy, slick, and ultimately cool GTK2 dialog variant that is destined to obselete the current GNOME dialog variant; GDialog. This is an OOPerl wrapper of the Zenity application.

DESCRIPTION

UI::Dialog::Backend::Zenity is the UI::Dialog backend for the new GNOME 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 zenity(1) application.
