Gtk2::main(3)

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)
