Gtk3 - Perl interface to the 3.x series of the gtk+ toolkit
SYNOPSIS
use Gtk3 -init;
my $window = Gtk3::Window->new ('toplevel');
my $button = Gtk3::Button->new ('Quit');
$button->signal_connect (clicked => sub { Gtk3::main_quit });
$window->add ($button);
$window->show_all;
Gtk3::main;
ABSTRACT
Perl bindings to the 3.x series of the gtk+ toolkit. 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 Gtk3 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 Gtk3 programs in Perl: <http://developer.gnome.org/gtk3/stable/>. The
Perl bindings follow the C API very closely, and the C reference documentation should be considered the canonical source.
To discuss Gtk3 and ask questions join gtk-perl-list@gnome.org at http://mail.gnome.org/mailman/listinfo/gtk-perl-list

Porting from Gtk2 to Gtk3
The majority of the API has not changed, so as a first approximation you can run "s/Gtk2/Gtk3/" on your application. A big exception to
this rule is APIs that were deprecated in gtk+ 2.x -- these were all removed from gtk+ 3.0 and thus from Gtk3. The migration guide at
<http://developer.gnome.org/gtk3/stable/migrating.html> describes what to use instead. Apart from this, here is a list of some other
incompatible differences between Gtk2 and Gtk3:
o The call syntax for class-static methods is now always "Gtk3::Stock::lookup" instead of "Gtk3::Stock->lookup".
o The %Gtk2::Gdk::Keysyms hash is gone; instead of "Gtk2::Gdk::Keysyms{XYZ}", use "Gtk3::Gdk::KEY_XYZ".
o The Gtk2::Pango compatibility wrapper was not carried over; simply use the namespace "Pango" everywhere. It gets set up automatically
when loading Gtk3.
o The Gtk3::Menu menu position callback passed to popup() does not receive x and y parameters anymore.
Note also that Gtk3::CHECK_VERSION will always fail when passed 2.y.z, so if you have any existing version checks in your code, you will
most likely need to remove them.

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.

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.
