Is there a way for the NPAPI plugin to fire an event on the homepage side? that is, the page containing the tag <embed> that instantiates the plugin.
<embed>
Disclaimer: I am an NPAPI newbie.
A way has been found: from the plugin's side, set the "addEventListener" method and use the JS interface to register "listeners".
When the event happens on the plugin side, pass through the "listeners".
