I've been trying to figure out a sane way to allow embeddors to do the force windows to open in tabs stuff that Firefox hacked in at some point. The current state of things is described at http://wiki.mozilla.org/DocShell:Window_targeting and what I think we want to do is at http://wiki.mozilla.org/DocShell:Window_targeting#Proposed_Changes. I was wondering what people think of the suggestion. I'm not sure whether a service is the right way to go or whether this is something that should live on the docshell tree owner... in particular, if we do a service-like thing then the callee will need to get from the nsIDOMWindow or nsIWebNavigation we pass in (one for some subframe) to something that would usefully allow them to open a tab in the same browser window, which might be nontrivial while sticking to frozen interfaces.

That's because there are several different things which all implement nsIWebProgress in different situations. For the embedding case, I believe http://www.mozilla.org/projects/embedding/PublicAPIs.html talks about nsIWebProgress and how to get one some. It seems I might use nsIWebBrowser-AddWebBrowserListener, where what it says is nsIWeakReference is really my nsIWebProgressListener. Yes, this would also work. Assuming the above is correct, to retrieve the HTTP status code (200, 302, 404, etc.), I think I would be concerned with OnStateChange in nsIWebProgressListener. Its documentation says NOTE: aStatus may be a success code even for server generated errors, such as the HTTP 404 error. In such cases, the request itself should be queried for extended error information (e.g., for HTTP requests see nsIHttpChannel). I'm apparently to use nsIHttpChannel somehow. Yes. How do I get one of those? I don't see anything in nsIRequest. You call QueryInterface on the request to nsIHttpChannel. If that succeeds, you're good to go. ;) If it fails, that wasn't an HTTP request. (I'm guessing that GetStatus method of nsIRequest will give me the same thing as aStatus in OnStateChange?) It should, yes. Grepping more, I see that in EmbedProgress.cpp, it do_QueryInterface an nsIRequest to an nsIChannel. Right. And annsIHttpChannel is an nsIChannel. Maybe I could do_QueryInterface to nsIHttpChannel, instead. Exactly. Then finally I call GetResponseStatus on the nsIHttpChannel object.

Sam Deane wrote: That answer seems to imply that on Windows at least, the content is double-buffered, including that rendered by plugins. Or did I misinterpret your answer? Well.. my answer was deliberately vague as to handling of plugins on Windows, because I simply don't know whether that ends up double-buffered or not for non-windowless plugins. If it's double buffered then I'm presuming everything is rendered into some sort of offscreen bitmap or drawing context which is then blitted to the screen. In which case it ought to be relatively easy to hook to the window update code and do something else with the buffer, instead of (or as well as) blitting it to the window. True. People who ask about rendering to memory usually want to do so without actually showing any windows on screen (and possibly without the ability to show such windows, eg a Unix box with no X server running). Which is a little more involved than what it sounds like you need. For our purposes we could probably hack things so that they are always in windowless mode, as long as the plugin supports it. I'm new to all this so I don't know - is it likely that most of the mainstream plugins will support it? The problem is that the plugin is what decides whether it's in windowless mode or not (and renders differently based on that). At least that's my understanding of the situation. That said, Flash and Java support windowless mode last I checked. Don't know about others. Would you have any idea who I could talk to about that floating code, or where I could find it?

Mac plugins apparently throw a fit when you try to double-buffer those pages...

References to children are now weak, so children only live as long as something outside the tree holds a reference to them. 2) When trying to add a child to an nsIDocShellTreeNode, it will actually have to be a docshell (there are other nsIDocShellTreeItems around, but they are no longer allowed in the docshell tree). 3) nsIDocumentLoader lost some methods (destroy() is gone, the container property is now read-only, createDocumentLoader() is gone). 4) nsIURILoader lost the getDocumentLoaderForContext method I plan to make other changes to docshell/webshell/docloader/uriloader in the near future, roughly as follows: A) Remove nsIWebShell (bug 273319) B) Remove most of what's left of nsIDocumentLoader (this is still not completely decided; see bug 273760).

Pretty much anything that's a layout/content/widget (and maybe gfx) header and is a .h instead of .idl is fair game. The actual criterion that's used is that if it's basically a private layout/content header (some of these interfaces shouldn't even be named nsIwhatever), it should be deCOMtaminated. Since i am using non-geko-sdk interfaces i need to modify my source for each release of Mozilla. Why do you need to use non-sdk interfaces? Especially ones subject to deCOMtamination? We should talk; perhaps we need to expose the functionality you need in some other way. -Boris ___ mozilla-embedding mailing list [EMAIL PROTECTED] http://mail.mozilla.org/listinfo/mozilla-embedding
