| 27 | Nothing much can be "imported" from this module right now. There are, |
29 | Nothing much can be "imported" from this module right now. |
| 28 | however, certain "import tags" that can be used to select the event model |
|
|
| 29 | to be used. |
|
|
| 30 | |
|
|
| 31 | Event models are implemented as modules under the C<Net::FCP::Event::xyz> |
|
|
| 32 | class, where C<xyz> is the event model to use. The default is C<Event> (or |
|
|
| 33 | later C<Auto>). |
|
|
| 34 | |
|
|
| 35 | The import tag to use is named C<event=xyz>, e.g. C<event=Event>, |
|
|
| 36 | C<event=Glib> etc. |
|
|
| 37 | |
|
|
| 38 | You should specify the event module to use only in the main program. |
|
|
| 39 | |
|
|
| 40 | If no event model has been specified, FCP tries to autodetect it on first |
|
|
| 41 | use (e.g. first transaction), in this order: Coro, Event, Glib, Tk. |
