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->run;

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

new

   $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.

loop_once

   $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.
