NAME
       "IO::Async::Loop::Glib" - use "IO::Async" with Glib or GTK

SYNOPSIS
	use IO::Async::Loop::Glib;

	my $loop = IO::Async::Loop::Glib->new();

	$loop->add( ... );

	...
	# Rest of GLib/Gtk program that uses GLib

	Glib::MainLoop->new->run();

       Or

	$loop->loop_forever();

       Or

	while(1) {
	   $loop->loop_once();
	}

DESCRIPTION
       This subclass of "IO::Async::Loop" uses the "Glib::MainLoop" to perform read-ready and write-ready tests.

       The appropriate "Glib::IO" sources are added or removed from the "Glib::MainLoop" when notifiers are added or removed from the set, or when
       they change their "want_writeready" status. The callbacks are called automatically by Glib itself; no special methods on this loop object
       are required.

CONSTRUCTOR
   $loop = IO::Async::Loop::Glib->new()
       This function returns a new instance of a "IO::Async::Loop::Glib" object. It takes no special arguments.

METHODS
       There are no special methods in this subclass, other than those provided by the "IO::Async::Loop" base class.

   $count = $loop->loop_once( $timeout )
       This method calls the "iteration()" method on the underlying "Glib::MainContext". If a timeout value is supplied, then a Glib timeout will
       be installed, to interrupt the loop at that time. If Glib indicates that any callbacks were fired, then this method will return 1 (however,
       it does not mean that any "IO::Async" callbacks were invoked, as there may be other parts of code sharing the Glib main context. Otherwise,
       it will return 0.
