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.
