NAME

       Gtk2::Ex::PrintDialog - a simple, pure Perl dialog for printing PostScript data in GTK+
       applications.

SYNOPSIS

               use Gtk2::Ex::PrintDialog;

               my $dialog = Gtk2::Ex::PrintDialog->new;        # a new dialog

               $dialog->set_data($postscript_data);            # supply some postscript data

               $dialog->set_filename($postscript_file);        # get postscript from a file

               $dialog->run;                                   # show the dialog to the user

DESCRIPTION

       This module implements a dialog widget that can be used to print PostScript data. It is
       intended to be a lightweight and pure-perl alternative to the Gnome2::Print libraries.

       This module uses a simple system of operating-system specific backends that are used to do
       the job of printing. Currently, only a generic Linux/Unix backend (implemented using
       Net::CUPS) is available, more will be added in the future.

       The dialog itself is intended to comply with the GNOME Human Interface Guidelines (HIG).
       It allows the user to print to any printer installed on the system, or to an external
       command such as "lpr", or to print a PostScript or PDF file.

       This module is UNSTABLE, the behaviour and API of its components may change in the future.

OBJECT HIERARCHY

         Glib::Object
         +----Gtk2::Object
              +----Gtk2::Widget
                   +----Gtk2::Container
                        +----Gtk2::Bin
                             +----Gtk2::Window
                                  +----Gtk2::Dialog
                                       +----Gtk2::Ex::PrintDialog

METHODS

               my $dialog = Gtk2::Ex::PrintDialog->new;

       Returns an instance of "Gtk2::Ex::PrintDialog". These dialogs are subclasse of
       "Gtk2::Dialog" so all corresponding methods, signals and properties from that class are
       also available.

       The dialog will handle user actions itself so you will probably not need to connect to any
       signals.

               $dialog->set_data($data);

       This tells the dialog to use the PostScript data in $data. This might be PostScript data
       you create yourself, or from another application. This data can subsequently retrieved
       using "get_data()".

               $dialog->set_filename($file);

       This tells the dialog to use the PostScript data in $file. The file name can be
       subsequently retrieved using "get_filename()". The contents of the file are read into
       memory when "set_filename()" is called, so any subequent calls to "get_data()" will return
       the contents of $file.

LOCALISATION ISSUES

       If the "Locale::gettext" module is available on the system, and your application uses it,
       all the strings used in the dialog will be automagically translated, as long as these
       default values are translated in your .mo files.

WRITING BACKENDS

       Backends are Perl modules with names of the form

               C<Gtk2::Ex::PrintDialog::$^O>

       See perlvar for details of the $^O variable. The module must have the following methods:

       "$backend = Gtk2::Ex::PrintDialog::$^O->new"
           The constructor.

       "$backend->get_printers"
           Returns an array of printer names.

       "$backend->print_file($printer, $file)"
           Prints the contents of $file to the printer named $file

       "$backend->get_default_print_command"
           Returns the path to the default print command, if applicable (eg '"lpr"')

       "$backend->can_print_pdf"
           Returns a true value if PDF printing is supported, "undef" otherwise.

       "$backend->print_to_pdf($data, $file)"
           Prints the PostScript data in $data to the PDF file named $file.

           Consult Gtk2::Ex::PrintDialog::Unix for an example. Please note that this interface
           may change in the future.

PREREQUISITES

       Gtk2
       Locale::gettext (recommended)
       Net::CUPS (for the Unix/Linux backend)
       Ghostscript, for the "ps2pdf" command (recommended)

SEE ALSO

       Gnome2::Print provides Perl bindings to the "offical" GNOME printing library. If you want
       a simple way to generate PostScript data, consider PostScript::Simple.

TO DO

       Implement a "Print Preview" function, maybe using Poppler.
       More backends.
