NAME

       UI::Dialog::Backend::XDialog - backend for the Xdialog(1)

SYNOPSIS

         use UI::Dialog::Backend::XDialog;
         my $d = new UI::Dialog::Backend::XDialog ( backtitle => 'Demo',
                                                    title => 'Default',
                                                    height => 20, width=>65,
                                                    listheight => 5 );

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

ABSTRACT

       UI::Dialog::Backend::XDialog is the UI::Dialog backend for the Xdialog(1) application.
       While this module is used through UI::Dialog or any other meta 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 Xdialog(1) application.

DESCRIPTION

       This backend is a wrapper for the Xdialog(1) application and as such attempts to extend
       every facet of Xdialog(1) to you the Perl programmer. The best reference for finding out
       about the various widgets, please read the fine Xdialog(1) manual as it's got the
       definitive details on the Xdialog application itself. This perldoc simply briefly
       describes all the supported options and widgets.

       Note that XDialog supports newlines (\n) within it's message text area, UI::Dialog strips
       the newlines in order to not break all the other backends. If you're using XDialog
       specifically, you can set the literal option to 1 and the message text will be left as it
       was literally given.

EXPORT

         None

INHERITS

         UI::Dialog::Backend

CONSTRUCTOR

   new( @options )
       EXAMPLE
            my $d = new( title => 'Default Title', backtitle => 'Backtitle',
                         width => 65, height => 20, listheight => 5 );

       DESCRIPTION
                 This is the Class Constructor method. It accepts a list of key => value pairs
                 and uses them as the defaults when interacting with the various widgets.

       RETURNS
                 A blessed object reference of the UI::Dialog::Backend::XDialog class.

       OPTIONS
           The (...)'s after each option indicate the default for the option. An * denotes
           support by all the widget methods on a per-use policy defaulting to the values decided
           during object creation.

WIDGET METHODS

   yesno( )
       EXAMPLE
              if ($d->yesno( text => 'A binary type question?') ) {
                  # user pressed yes
              } else {
                  # user pressed no or cancel
              }

       DESCRIPTION
             Present the end user with a message box that has two buttons, yes and no.

       RETURNS
             TRUE (1) for a response of YES or FALSE (0) for anything else.

   msgbox( )
       EXAMPLE
              $d->msgbox( text => 'A simple message' );

       DESCRIPTION
             Pesent the end user with a message box that has an OK button.

       RETURNS
             TRUE (1) for a response of OK or FALSE (0) for anything else.

   infobox( )
       EXAMPLE
              $d->infobox( text => 'Information to convey.', timeout => 5000 );

       DESCRIPTION
             Present the end user with a message box that disappears after a certain length of
             time. The 'timeout' argument is representative of milliseconds. The default timeout
             is 5000 milliseconds (5 seconds). Yes this message will self destruct!  You can also
             use the alternate timeout option of 'wait' in which is interpreted in seconds
             instead of milliseconds

       RETURNS
             TRUE (1) for a response of OK / normal timeout or FALSE (0) for anything else.

   gauge_start( ) progress_start( )
       EXAMPLE

       DESCRIPTION
                 Display a meter bar to the user. This get's the widget realized but requires the
                 use of the other gauge_*() methods for functionality. There are two such meter
                 bars provided by Xdialog(1) and both are handled independantly of each other.
                 This allows for an interesting situation... two progress meters up at the same
                 time, both fully functional.
