=head1 SYNOPSIS |
| 6 |
|
| 7 |
use Glib::Event; |
| 8 |
|
| 9 |
# example with Gtk2: |
| 10 |
use Gtk2 -init; |
| 11 |
use Glib::Event; |
| 12 |
use Event; # any order |
| 13 |
Event->timer (after => 1, interval => 1, cb => sub { print "I am here!\n" }); |
| 14 |
main Gtk2; |
| 15 |
# etc., it just works |
| 16 |
|
| 17 |
# You can even move the glib mainloop into a coroutine: |
| 18 |
use Gtk2 -init; |
| 19 |
use Coro; |
| 20 |
use Coro::Event; |
| 21 |
use Glib::Event; |
| 22 |
async { main Gtk2 }; |
| 23 |
# ... do other things |

=head1 DESCRIPTION |
| 26 |
|
| 27 |
This module coerces the Glib event loop to use the Event module as |
| 28 |
underlying event loop, i.e. Event will be used by Glib for all events. |
| 29 |
|
| 30 |
This makes Glib compatible to Event. Calls into the Glib main loop |
| 31 |
are more or less equivalent to calls to C<Event::loop>. |
| 32 |

=item * The Glib perl module is not used. |
| 36 |
|
| 37 |
This module has no dependency on the existing Glib perl interface, as it |
| 38 |
uses glib directly. The Glib module can, however, be used without any |
| 39 |
problems. |
| 40 |
|
| 41 |
=item * The default context will be changed when the module is loaded. |
| 42 |
|
| 43 |
Loading this module will automatically "patch" the default context of |
| 44 |
libglib, so normally nothing more is required. |
| 45 |
|
| 46 |
=item * Glib does not allow recursive invocations. |
| 47 |
|
| 48 |
This means that none of your event watchers might call into Glib |
| 49 |
functions or functions that might call glib functions (basically all Gtk2 |
| 50 |
functions). It might work, but that's your problem.... |

| 75 |
|
| 76 |
* No documented API to patch other main contexts. |
| 77 |
* Uses one_event, which is inefficient. |
