gtk event handling in plugins question

Hey all,

I have a question WRT event handling in plugins with GTK. I'm trying to 
expose some native GUI controls in a XUL app on linux by using a 
scriptable plugin as an adapter. I want to wrap the use of this plugin 
in an XBL widget.

I want the XBL widget to catch all the events so that app level accel 
keys and context menus get handled by the XUL part of the dialog and 
have the XBL widget hand off the things I want the native control to get 
via the scriptable interface. My problem is my gtk knowledge is lacking 
in how to configure the plugin widget/window to not catch events and let 
the XBL binding handle it. If I replace the <html:embed> element in my 
binding with a regular XUL element, the handlers pick up events ok, but 
with the embedded object they always go to the plugin.

I've been through the code to the simple events test, checked out the 
abimoz plugin, and looked at the docs for gtk. I suspect that the answer 
has been staring me in the face and I'm just missing it. Any pointers to 
where specifically I should look to find out what I'm doing wrong would 
be appreciated.

Thanks
