=head1 DESCRIPTION |
| 10 |
|
|
|
| 11 |
|
|
If you want to use EV in a glib/gtk+ program, then you need to look at |
| 12 |
|
|
the Glib::EV module, not this one, as this module requires you to run EV |
| 13 |
|
|
in your main program. |
| 14 |
|
|
|
| 15 |
|
|
If you want to use glib/gtk+ in an EV program, you are at the right place |
| 16 |
|
|
here. |
| 17 |
|
|
|
| 18 |
|
|
This module embed the glib main loop into EV, that is, EV will also handle |
| 19 |
|
|
Glib events. |
| 20 |
|
|
|
| 21 |
|
|
This makes Glib compatible to EV. Calls into the EV main loop are more |
| 22 |
|
|
or less equivalent to calls to Glib::MainLoop (but not vice versa, you |
| 23 |
|
|
I<have> to use the EV loop functions). |

=item * The Glib perl module is not used. |
| 28 |
|
|
|
| 29 |
|
|
This module has no dependency on the existing Glib perl interface, as it |
| 30 |
|
|
uses glib directly. The Glib module can, however, be used without any |
| 31 |
|
|
problems (as long as evereybody uses shared libraries to keep everybody |
| 32 |
|
|
else happy). |
| 33 |
|
|
|
| 34 |
|
|
=item * The default context will be added to EV when the module is loaded. |
| 35 |
|
|
|
| 36 |
|
|
Loading this module will automatically integrate the default context into |
| 37 |
|
|
EV, so normally nothing else is required. |
| 38 |
|
|
|
| 39 |

=item * There will be no g_main_loop or gtk_main loop available. |
| 40 |
|
|
|
| 41 |
|
|
The EV event loop is not the gtk+ main loop. That means that things like |
| 42 |
root |
1.4 |
C<gtk_main_quit> will not work at all, as there is no glib mainloop. You |
| 43 |
|
|
I<have> to use EV's equivalents, i.e. C<EV::unloop>. |
| 44 |
root |
1.2 |
|
| 45 |
root |
1.3 |
=item * You cannot call any glib loop functions while its context is active. |
| 46 |
|
|
|
| 47 |
|
|
This module uses a prepare watcher at lowest priority to dispatch glib |
| 48 |
|
|
events and activate the main context. The context will be deactivates in a |
| 49 |
|
|
check watcher of highest priority. |
| 50 |
|
|
|
| 51 |
|
|
That means that glib events will be dispatched with lowest priority, and |
| 52 |
|
|
that you cannot call any glib main functions (or functions calling it) on |
| 53 |
|
|
the default mainloop in highest-priority watchers and in lowest-priority |
| 54 |
|
|
prepare watchers. |
| 55 |
|
|
|
| 56 |
root |
1.4 |
=item * EV::Glib watchers will (currently) keep the mainloop alive. |
| 57 |
|
|
|
| 58 |
|
|
That means that, after loading this module, C<EV::loop> calls will never |
| 59 |
|
|
return unless you call C<EV::unloop> explicitly. Future versions might fix |
| 60 |
|
|
this problem so that Glib keeps the EV loop alive only when it has active |
| 61 |
|
|
events waiting. |
