NAME

       Gtk2 - Perl interface to the 2.x series of the Gimp Toolkit library

SYNOPSIS

         use Gtk2 -init;
         # Gtk2->init; works if you didn't use -init on use
         my $window = Gtk2::Window->new ('toplevel');
         my $button = Gtk2::Button->new ('Quit');
         $button->signal_connect (clicked => sub { Gtk2->main_quit });
         $window->add ($button);
         $window->show_all;
         Gtk2->main;

ABSTRACT

       Perl bindings to the 2.x series of the Gtk+ widget set.  This module allows you to write graphical user
       interfaces in a Perlish and object-oriented way, freeing you from the casting and memory management in C,
       yet remaining very close in spirit to original API.

DESCRIPTION

       The Gtk2 module allows a Perl developer to use the Gtk+ graphical user interface library.  Find out more
       about Gtk+ at http://www.gtk.org.

       The GTK+ Reference Manual is also a handy companion when writing Gtk programs in any language.
       http://developer.gnome.org/doc/API/2.0/gtk/ The Perl bindings follow the C API very closely, and the C
       reference documentation should be considered the canonical source.

       To discuss gtk2-perl, ask questions and flame/praise the authors, join gtk-perl-list@gnome.org at
       lists.gnome.org.

INITIALIZATION

         use Gtk2 qw/-init/;
         use Gtk2 qw/-init -threads-init/;

       -init
           Equivalent  to  Gtk2->init,  called  to  initialize  GLIB and GTK+. Just about every Gtk2-Perl script
           should do "use Gtk2 -init"; This initialization  should  take  place  before  using  any  other  Gtk2
           functions  in  your GUI applications. It will initialize everything needed to operate the toolkit and
           parses some standard command line options. @ARGV is adjusted accordingly so your own code will  never
           see those standard arguments.

       -threads-init
           Equivalent  to Gtk2::Gdk::Threads->init, called to initialze/enable gdk's thread safety mechanisms so
           that   gdk   can   be   accessed   from   multiple   threads   when   used   in   conjunction    with
           Gtk2::Gdk::Threads->enter  and  Gtk2::Gdk::Threads->leave.  If invoked as Gtk2::Gdk::Threads->init it
           should be done before Gtk2->init is called, if done by "use Gtk2 -init -threads-init" order does  not
           matter.

EXPORTS

       Gtk2 exports nothing by default, but some constants are available upon request.

       Tag: constants
             GTK_PRIORITY_RESIZE

             GTK_PATH_PRIO_LOWEST
             GTK_PATH_PRIO_GTK
             GTK_PATH_PRIO_APPLICATION
             GTK_PATH_PRIO_THEME
             GTK_PATH_PRIO_RC
             GTK_PATH_PRIO_HIGHEST

             GDK_PRIORITY_EVENTS
             GDK_PRIORITY_REDRAW
             GDK_CURRENT_TIME

       See Glib for other standard priority levels.

SEE ALSO

       perl(1), Glib(3pm), Pango(3pm).

       Gtk2::Gdk::Keysyms(3pm) contains a hash of key codes, culled from gdk/gdkkeysyms.h

       Gtk2::api(3pm)  describes  how  to  map the C API into Perl, and some of the important differences in the
       Perl bindings.

       Gtk2::Helper(3pm) contains stuff that makes writing Gtk2 programs a little easier.

       Gtk2::SimpleList(3pm) makes the GtkListStore and GtkTreeModel a lot easier to use.

       Gtk2::Pango(3pm) exports various little-used but important constants you may  need  to  work  with  pango
       directly.

       Gtk2::index(3pm) lists the autogenerated api documentation pod files for Gtk2.

       Gtk2  also  provides code to make it relatively painless to create Perl wrappers for other GLib/Gtk-based
       libraries.  See Gtk2::CodeGen, ExtUtils::PkgConfig, and ExtUtils::Depends.  If you're  writing  bindings,
       you'll  probably also be interested in Gtk2::devel, which is a supplement to Glib::devel and Glib::xsapi.
       The Binding Howto, at http://gtk2-perl.sourceforge.net/doc/binding_howto.pod.html, ties it all together.
