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.

UI::Dialog::Backend

CONSTRUCTOR

new( @options )

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

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

DESCRIPTION
Pesent the end user with a message box that has an OK button.
TRUE (1) for a response of OK or FALSE (0) for anything else.

infobox( )

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

 $d->gauge_start( text => 'gauge...', percentage => 1 );
 $d->progress_start( text => 'progres...', percentage => 1 );
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. 

 #
 # Progressive Duality :)
