# example with Gtk2: |

|
|
use Gtk2 -init; |

|
|
use Glib::EV; |
| 12 |
|
|
use EV; # any order |

|
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; |

use Coro; |

|
|
use Coro::EV; |

=head1 DESCRIPTION |

1.3 |
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 |

1.1 |
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). |

|
=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 |
root |
1.4 |
problems (as long as everybody uses shared libraries to keep everybody |
| 49 |
root |
1.1 |
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.... |
