Hello,

I need to execute JavaScript code in my app that hosts Gecko. This code
needs to be executed in the browser's context. Looking at the code, I
could use it by using nsIScriptContext interface, but it doesn't look
like something acceptable for me. It's a very internal interface itself,
and it's even worse with ways to get it. I've found that I could get it
from nsIGlobalObject gotten from QI nsIDOMWindow (how to get it? content
window doesn't seem to work here) or nsIDocument. Whole this needs
definitely too much internal stuff to be acceptable for me (these
interface are not even declared in IDLs).

So my question is: is there any good way to do it?

I already started writing a patch to add such API to Gecko. My idea is
adding a wrapper interface exported by the document object that would
hide nsIScriptContext internals. Do you thing it's a good way to go? Or
should it be implemented in an other place?

Thanks,
    Jacek Caban
