Re: non-gui usage of Gtk2::MozEmbed

["Nickolay Platonov" <nickolay8 gmail com>]

Ups, seems I was replying to each interlocutor personally, and not via mailing list, sorry..

Currently my progress is: I have a small separate perl script (http://rafb.net/p/IRsq5r59.html) which I'm using to receive an innerHTML of the particularly URL.  
This script works only in presence of X server (you were right Tadej), so I'm using Xvfb (many thanks to Dave for this clue).

But it works differently on my development machine (which is making requests to remote DB) and my production server (on which requests to DB are local).
It seems that for production server the "net_stop" event occurs a bit early - when the page is not fully complete yet.

It seems I'll need to replace the "net_stop" event to some kind of custom _javascript_ event, like described here:
https://developer.mozilla.org/En/Mozilla_Embedding_FAQ/How_do_I...
( "I need the _javascript_ inside the browser window to talk to my embedding client. How do I do it?" section)

Many thanks to everyone for the help already provided..

Regards, Nickolay

Hi.

I'm guessing now, but what happens if you call realize method on your
embed object?
