=head1 SYNOPSIS |
| 6 |
|
| 7 |
use Glib::EV; |
| 8 |
|
| 9 |
# example with Gtk2: |
| 10 |
use Gtk2 -init; |
| 11 |
use Glib::EV; |
| 12 |
use EV; # any order |
| 13 |
my $timer = EV::timer 1, 1, 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::EV; |
| 21 |
use Glib::EV; |
| 22 |
async { main Gtk2 }; |
| 23 |
# ... do other things |

=head1 DESCRIPTION |
| 26 |
|
| 27 |
If you want to use glib/gtk+ in an EV program, then you need to look at |
| 28 |
the EV::Glib module, not this one, as this module requires you to run a |
| 29 |
Glib or Gtk+ main loop in your program. |
| 30 |
|
| 31 |
If you want to use EV in an Glib/Gtk+ program, you are at the right place |
| 32 |
here. |
| 33 |
|
| 34 |
This module coerces the Glib event loop to use the EV high performance |
| 35 |
event loop as underlying event loop, i.e. EV will be used by Glib for all |
| 36 |
events. |
| 37 |
|
| 38 |
This makes Glib compatible to EV. Calls into the Glib main loop are more |
| 39 |
or less equivalent to calls to C<EV::loop> (but not vice versa, you |
| 40 |
I<have> to use the Glib mainloop functions). |
| 41 |

=item * The Glib perl module is not used. |
| 45 |
|
| 46 |
This module has no dependency on the existing Glib perl interface, as it |
| 47 |
uses glib directly. The Glib module can, however, be used without any |
| 48 |
problems (as long as everybody uses shared libraries to keep everybody |
| 49 |
else happy). |
| 50 |
|
| 51 |
=item * The default context will be changed when the module is loaded. |
| 52 |
|
| 53 |
Loading this module will automatically "patch" the default context of |
| 54 |
libglib, so normally nothing more is required. |
| 55 |
|
| 56 |
=item * Glib does not allow recursive invocations. |
| 57 |
|
| 58 |
This means that none of your event watchers might call into Glib |
| 59 |
functions or functions that might call glib functions (basically all Gtk2 |
| 60 |
functions). It might work, but that's your problem.... |
