=head1 METHODS

=head2 boolean = Gtk2-E<gt>B<alternative_dialog_button_order> ($screen=undef)

=over

=item * $screen (Gtk2::Gdk::Screen or undef) 

=back

Since: gtk+ 2.6

=head2 event or undef = Gtk2-E<gt>B<get_current_event> 

=head2 modifiertype = Gtk2-E<gt>B<get_current_event_state> 

=head2 unsigned = Gtk2-E<gt>B<get_current_event_time> 

=head2 language = Gtk2-E<gt>B<get_default_language> 

=head2 Gtk2-E<gt>B<disable_setlocale> 

=head2 widget or undef = Gtk2-E<gt>B<get_event_widget> ($event)

=over

=item * $event (Gtk2::Gdk::Event or undef) 

=back

=head2 integer = Gtk2-E<gt>B<events_pending> 

=head2 Gtk2-E<gt>B<grab_add> ($widget)

=over

=item * $widget (Gtk2::Widget) 

=back

=head2 widget or undef = Gtk2-E<gt>B<grab_get_current> 

=head2 Gtk2-E<gt>B<grab_remove> ($widget)

=over

=item * $widget (Gtk2::Widget) 

=back

=head2 boolean = Gtk2-E<gt>B<init> 

Initialize Gtk+.  This must be called before any other Gtk2 functions in a 
GUI application; the Gtk2 module's import method allows you to pass C<-init>
in the C<use> statement to do this automatically.  This function also scans
I<@ARGV> for any options it knows, and will remove them automagically.

Note: this function will terminate your program if it is unable to initialize
the gui for any reason.  If you want your program to fall back to some other
interface, you want to use C<< Gtk2->init_check >> instead.

=head2 Gtk2-E<gt>B<init_add> ($function, $data=undef)

=over

=item * $function (scalar) 

=item * $data (scalar) 

=back

=head2 boolean = Gtk2-E<gt>B<init_check> 

This is the non-fatal version of C<< Gtk2->init >>; instead of calling C<exit>
if Gtk+ initialization fails, C<< Gtk2->init_check >> returns false.  This
allows your application to fall back on some other means of communication with
the user - for example a curses or command-line interface.

=head2 integer = Gtk2-E<gt>B<key_snooper_install> ($snooper, $func_data=undef)

=over

=item * $snooper (subroutine) function to call on every event

=item * $func_data (scalar) 

=back

Install a key "snooper" function which will get called on all key
events before those events are delivered normally.  These snoopers can
be used to implement custom key event handling.

C<key_snooper_install> returns an id that may be used with
C<key_snooper_remove> (below).  I<snooper> is called as

    stopbool = &snooper ($widget, $event, $func_data);

It should return true to stop event propagation, the same as
C<Gtk2::Widget> event signal handlers.  The C<Gtk2::EVENT_STOP> and
C<Gtk2::EVENT_PROPAGATE> constants can be used for the return (see
L<Gtk2::Widget>).

=head2 Gtk2-E<gt>B<key_snooper_remove> ($snooper_handler_id)

=over

=item * $snooper_handler_id (integer) 

=back

=head2 string = Gtk2-E<gt>B<set_locale> 

=head2 Gtk2-E<gt>B<main> 

=head2 Gtk2-E<gt>B<main_do_event> ($event)

=over

=item * $event (Gtk2::Gdk::Event) 

=back

This is the event handler that GTK+ registers with GDK.  GTK+ exposes it to
allow filtering of events between GDK and GTK+; it is rare that you would
need this, except if you are using C<Gtk2::Gdk::Event::handler_set>.

=head2 boolean = Gtk2-E<gt>B<main_iteration>

=item * $open_default_display (boolean) 

=back

Since: gtk+ 2.6

=head2 boolean = Gtk2-E<gt>B<parse_args> 

Since: gtk+ 2.4
