NAME

       Gtk2::main

METHODS

   boolean = Gtk2->alternative_dialog_button_order ($screen=undef)
       •   $screen (Gtk2::Gdk::Screen or undef)

       Since: gtk+ 2.6

   event or undef = Gtk2->get_current_event
   modifiertype = Gtk2->get_current_event_state
   unsigned = Gtk2->get_current_event_time
   language = Gtk2->get_default_language
   Gtk2->disable_setlocale
   widget or undef = Gtk2->get_event_widget ($event)
       •   $event (Gtk2::Gdk::Event or undef)

   integer = Gtk2->events_pending
   Gtk2->grab_add ($widget)
       •   $widget (Gtk2::Widget)

   widget or undef = Gtk2->grab_get_current
   Gtk2->grab_remove ($widget)
       •   $widget (Gtk2::Widget)

   boolean = Gtk2->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 "-init" in the "use"
       statement to do this automatically.  This function also scans @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 "Gtk2->init_check" instead.

   Gtk2->init_add ($function, $data=undef)
       •   $function (scalar)

       •   $data (scalar)

   boolean = Gtk2->init_check
       This is the non-fatal version of "Gtk2->init"; instead of calling "exit" if Gtk+
       initialization fails, "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.

   integer = Gtk2->key_snooper_install ($snooper, $func_data=undef)
       •   $snooper (subroutine) function to call on every event

       •   $func_data (scalar)

       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.

       "key_snooper_install" returns an id that may be used with "key_snooper_remove" (below).
       snooper is called as

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

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

   Gtk2->key_snooper_remove ($snooper_handler_id)
       •   $snooper_handler_id (integer)

   string = Gtk2->set_locale
   Gtk2->main
   Gtk2->main_do_event ($event)
       •   $event (Gtk2::Gdk::Event)

       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 "Gtk2::Gdk::Event::handler_set".

   boolean = Gtk2->main_iteration
   boolean = Gtk2->main_iteration_do ($blocking)
       •   $blocking (boolean)

   integer = Gtk2->main_level
   Gtk2->main_quit
   optiongroup = Gtk2->get_option_group ($open_default_display)
       •   $open_default_display (boolean)

       Since: gtk+ 2.6

   boolean = Gtk2->parse_args
       Since: gtk+ 2.4

   integer = Gtk2->quit_add ($main_level, $function, $data=undef)
       •   $main_level (integer)

       •   $function (scalar)

       •   $data (scalar)

   Gtk2->quit_add_destroy ($main_level, $object)
       •   $main_level (integer)

       •   $object (Gtk2::Object)

   Gtk2->quit_remove ($quit_handler_id)
       •   $quit_handler_id (integer)

   Gtk2::show_uri ($screen, $uri, $timestamp=GDK_CURRENT_TIME)
       •   $screen (Gtk2::Gdk::Screen or undef)

       •   $uri (string)

       •   $timestamp (unsigned)
