Description:
An event triggering feedback to the user
Event represents an event that should trigger audio, haptic and/or visual feedback to the user by triggering feedback on a feedback daemon. Valid event names are specified in the [Event naming specification](Event-naming-spec-0.0.0.html).
One event can trigger multiple feedbacks at once (e.g. audio and haptic feedback). This is determined by the feedback theme in use (which is not under the appliction's control) and the active feedback profile (see [func@Lfb.set_feedback_profile].
After initializing the library via [func@Lfb.init] feedback can be triggered like:
```c g_autoptr (GError) err = NULL; LfbEvent *event = lfb_event_new ("message-new-instant"); lfb_event_set_timeout (event, 0); if (! lfb_event_trigger_feedback (event, &err)) g_warning ("Failed to trigger feedback: s", err-> message); ```
When all feedback for this event has ended the [signal@LfbEvent:LfbEvent:feedback-ended] signal is emitted. If you want to
end the feedback ahead of time use [method@LfbEvent.end_feedback]:
```c if (!lfb_event_end_feedback (event, &err)) g_warning ("Failed to end feedback: s", err-> message); ```
Since these methods involve DBus calls there are asynchronous variants available, e.g. [method@LfbEvent.trigger_feedback_async]:
```c static void on_feedback_triggered (LfbEvent *event, GAsyncResult *res, gpointer unused) { g_autoptr (GError) err = NULL; if ( !lfb_event_trigger_feedback_finish (event, res, &err)) { g_warning ("Failed to trigger feedback for s : s", lfb_event_get_event (event), err->message); } }
static void my_function () { LfbEvent *event = lfb_event_new ("message-new-instant"); lfb_event_trigger_feedback_async (event, NULL, (GAsyncReadyCallback)on_feedback_triggered, NULL); } ```
