NAME

       UI::Dialog - wrapper for various dialog applications.

SYNOPSIS

         use UI::Dialog;
         my $d = new UI::Dialog ( backtitle => 'Demo', title => 'Default',
                                  height => 20, width => 65 , listheight => 5,
                                  order => [ 'zenity', 'xdialog' ] );

         # Either a Zenity or Xdialog msgbox widget should popup,
         # with a preference for Zenity.
         $d->msgbox( title => 'Welcome!', text => 'Welcome one and all!' );

ABSTRACT

       UI::Dialog is a OOPerl wrapper for the various dialog applications. These dialog backends
       are currently supported: Zenity, XDialog, GDialog, KDialog, CDialog, and Whiptail. There
       is also an ASCII backend provided as a last resort interface for the console based dialog
       variants. UI::Dialog is a class that provides a strict interface to these various backend
       modules.  By using UI:Dialog (with it's imposed limitations on the widgets) you can ensure
       that your Perl program will function with any available interfaces.

DESCRIPTION

       UI::Dialog supports priority ordering of the backend detection process. So if you'd prefer
       that Xdialog should be used first if available, simply designate the desired order when
       creating the new object. The default order for detecting and utilization of the backends
       are as follows:
         (with DISPLAY env): Zenity, GDialog, XDialog, KDialog
         (without DISPLAY): CDialog, Whiptail, ASCII

       UI::Dialog is the result of a complete re-write of the UDPM CPAN module. This was done to
       break away from the bad choice of name (UserDialogPerlModule) and to implement a cleaner,
       more detached, OOPerl interface.

CONSTRUCTOR

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

       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 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.

           debug = 0,1,2 (0)
           order = [ zenity, xdialog, gdialog, kdialog, cdialog, whiptail, ascii ] (as indicated)
           PATH = [ /bin, /usr/bin, /usr/local/bin, /opt/bin ] (as indicated)
           backtitle = "backtitle" ('') *
           title = "title" ('') *
           beepbefore = 0,1 (0) *
           beepafter = 0,1 (0) *
           height = \d+ (20) *
           width = \d+ (65) *
           listheight = \d+ (5) *

       RETURNS
                 a SCALAR.

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.

   inputbox( )
       EXAMPLE
            my $string = $d->inputbox( text => 'Please enter some text...',
                                       entry => 'this is the input field' );

       DESCRIPTION
                 Present the end user with a text input field and a message.

       RETURNS
                 a SCALAR if the response is OK and FALSE (0) for anything else.

   password( )
       EXAMPLE
            my $string = $d->password( text => 'Enter some hidden text.' );

       DESCRIPTION
                 Present the end user with a text input field, that has hidden input, and a
                 message.

                 Note that the GDialog backend will provide a regular inputbox instead of a
                 password box because gdialog doesn't support passwords. GDialog is on it's way
                 to the proverbial software heaven so this isn't a real problem. Use Zenity
                 instead :)
