-===== Throwing Events ===== +
-You can also throw events, by using the function **qa_report_event()** which is defined in **qa-base.php**. This is a good way to create interaction between plugins, without having to worry if both plugins are installed. If any of them aren't, the event just will never get thrown and the programmer don't need to check if it's installed+
-To throw an event, just do like the code below: +
-<code php> +
-qa_report_event("u_pm_sent", qa_get_logged_in_userid(), qa_get_logged_in_handle(), qa_cookie_get_create(), array( +
- "param1" => $var1, +
- "param2" => $var2 +
- )); +
-</code> +
-The first param is the name of the event. When catching events, this is gonna be the content of the **$event** var. +
-The second one is the id of the logged user, the third is the handle/username of the user and the third is the cookie. +
-The last is an ''array'' with custom parameters you may want to pass regarding to your eventThey may be how many you want and have the names you want.  +
