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.

Also have a look at the gtk2-perl website and sourceforge project page, http://gtk2-perl.sourceforge.net

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.
