Re: Embedding Gecko/XULRunner

I think am able to initialise the browser by QI-ing for nsBaseWindow
and then init and then create. I think it s initialised properly
because the return code on loading a URL through nsIWebNavigation is
OK.
I am not displaying anything since I am trying to run offscreen and I
only have the codes to work with. However, I cannot get to the
nsIDOMWindow (I get null) by doing:

nsCOMPtr<nsIDOMWindow> mDomWin;
mWebBrowser->GetContentDOMWindow(getter_AddRefs(mDomWin));

Any suggestions??
Here is a snippet with all the initialisations going on:


nsCOMPtr<nsIWebBrowser> mWebBrowser =
do_CreateInstance(NS_WEBBROWSER_CONTRACTID, &rv);
    if (NS_FAILED(rv)) {
        std::cout << "Couldn't create Web Browser" << std::endl;
        exit(1);
    }

    nsCOMPtr<nsIWebNavigation> mWebNav =
do_QueryInterface(mWebBrowser, &rv);
    if (NS_FAILED(rv)) {
        std::cout << "Couldn't create Web Nav" << std::endl;
        exit(1);
    }

    nsCOMPtr<nsIBaseWindow> baseWindow =
do_QueryInterface(mWebBrowser, &rv);
    if (NS_FAILED(rv)) {
        std::cout << "Couldn't QI base win" << std::endl;
        exit(1);
    }

    WebBrowserChrome *cw = new WebBrowserChrome();
    mWebBrowser->SetContainerWindow(static_cast<nsIWebBrowserChrome*>
(cw));

    WebBrowserChromeUI *nw = new WebBrowserChromeUI(); //empty - I
dont want to display stuff
    rv = baseWindow->InitWindow(nw, nsnull, 0, 0, 0, 0);
    if (NS_FAILED(rv)) {
        std::cout << "Couldn't init base win" << std::endl;
        exit(1);
    }

    rv = baseWindow->Create();
    if (NS_FAILED(rv)) {
        std::cout << "Couldn't create base win" << std::endl;
        exit(1);
    }

    rv = mWebNav->LoadURI(
            NS_ConvertASCIItoUTF16("http://www.google.com/").get(),
            nsIWebNavigation::LOAD_FLAGS_NONE,
            nsnull,
            nsnull,
            nsnull);
    if (NS_FAILED(rv)) {
        std::cout << "Couldn't load URL: " << std::endl;
        exit(1);
    } else {
        std::cout << "Maybe loaded url" << std::endl; //reaches
here :) :) :)
    }



    nsCOMPtr<nsIDOMDocument> mDomDoc;
    nsCOMPtr<nsIDOMWindow> mDomWin;
    rv = mWebBrowser->GetContentDOMWindow(getter_AddRefs(mDomWin));
    if(mDomWin) { // mDomWin is NULL here :( :( :(
        mDomWin->GetDocument(getter_AddRefs(mDomDoc));
        if(!mDomDoc)
            std::cout << "Cannot get DOM doc" << std::endl;
    } else {
        std::cout << "Cannot get dom win " << std::endl;
    }
