Make sure you have read part three of this series about NPObjects so that you understand how it works. You're going to implement the addEventListener method on your NPObject that expects three parameters, just like any element. the function when it gets to you will be an NPObject*. Read up on the npapi memory management post on this site for information on how retainobject works. Save the NPObject* to the function, which is your event handler, and call NPN_Invoke when you want to "fire" the event. Make sure it's on the main thread. Keep in mind, this is not a simple topic.

I could n`t create and fire event in my npruntime plugin .I did try to see your framework code that firebreat code.But i could n`t understand because i am new in this area .Your code is have a lot of line .I need just create one event and fire from firefox plugin.Can you explain or share that limit of code or your post link about event ? I saw your reply to sleepy about event. "When they call addEventListener, the parameter that is a function gets passed in as an NPObject *; NPN_RetainObject this and store it in a multimap or similar with the name of the event as the key. When they call removeEventListener, search through and see if you have a saved pointer to the passed-in npobject; if so, NPN_ReleaseObject it and delete your saved pointer. When you need to fire an event, marshall the arguments you want as an array of NPObjects and loop through all of the saved npobjects for that event and call NPN_InvokeDefault on each of them. " I couldn`t understand ,function gets passed in as an NPObject *; NPN_RetainObject and invoke NPN function.

“When they call addEventListener, the parameter that is a function gets passed in as an NPObject *; NPN_RetainObject this and store it in a multimap or similar with the name of the event as the key.

When they call removeEventListener, search through and see if you have a saved pointer to the passed-in npobject; if so, NPN_ReleaseObject it and delete your saved pointer.

I couldn`t understand ,function gets passed in as an NPObject *; NPN_RetainObject and invoke NPN function.

Please read my other posts, and particularly look at using FireBreath, which simplifies a lot of things, particularly if you are new in the area.
