== Weekly Summaries Notice ==None yetThere is already an [http://developer.mozilla.org/en/docs/Mozilla_Embedding_FAQ embedding FAQ on mozilla] that probably wasn't properly linked in with Mozilla's FAQ page.

You can find a examples, FAQs, and the API from [http://www.mozilla.org/projects/embedding/ mozilla] itself. <br/>You can get more detailed information on what interfaces are required and which are optional to impelement [http://developer.mozilla.org/en/docs/Gecko_Embedding_Basics here]. Scroll down to "Initalization and Teardown. ===How to customize document retrieval===One method is to implement your own protocol method. You can find more information on adding new protocols [http://kb.mozillazine.org/Dev_:_Protocol_Handlers here] ===How to embedding mozilla inside of Java===There hasn't been any good code examples found. However, there is a stripped down, uncommented code with eclipse libraries in [http://groups.google.com/group/mozilla.dev.embedding/browse_thread/thread/46c259db088ee584/76f2073388eaffdd#76f2073388eaffdd this] thread.

Then pass the object to your XPCOM coded object and call it from C++.

You get no text and no functionality. There are two possible solutions to this error.#The Dialog is not handled by the prompt service. You must implement another interface (for example, nsIBadCertListener)#The original dialog does not work correctly because your application is not handling chrome correctly. Here are some things other people have used to solve their problems : #*This will get the text in the security popup and allow you to view the certificate : <br/> In the nsIWindowCreator::CreateChromeWindow() implementation, change the doc shell tree item's type to ''nsIDocShellTreeItem::typeChromeWrapper'' to ''nsIDocShellTreeItem::typeContentWrapper'' to view the certificate. You can nsIWebBrowserChrome::CHROME_OPENAS_CHROME to check when to use typeChromeWrapper and typeContentWrapper#*This will tell the browser to progress to the secure site <code> :nsCOMPtr<nsIJSContextStack> stack(do_GetService("@mozilla.org/js/xpc/ContextStack;1")); if (stack && NS_SUCCEEDED(stack->Push(nsnull))) { /* Display the modal window here */ JSContext* cx; stack->Pop(&cx); }</code> === How to control what is, and what is not, loaded ===Some people have complained that nsIURIContentListener::OnStartURIOpen() is not called for logos (images) and CSS.

The program and code is available [http://ubrowser.com/testapps.php here] === Why does TestGTKEmbed give an error message when I download something and 'save as/ open with' pops up? ===You have to implement your own download UI as gtkmozembed doesn't have one. Alternatively, you can download files using nsIWebBrowserPersist if UI isn't a concern. === How to rebuild tests in only part of the Mozilla Suite ===Go into the folder where the tests are found and issue make. If you built mozilla with an object directory, you must change into that directory into there first. === How do I render strings provided by the user? ===use the nsIWebBrowserStream. You can get it by a do_QueryInterface() on the nsIWebBrowser you use. Look at the file [http://lxr.mozilla.org/mozilla1.8.0/source/embedding/browser/gtk/src/EmbedPrivate.cpp embedding/browser/gtk/src/EmbedPrivate.cpp] and the methods OpenStream(), AppendToStream(), and CloseStream() to get sample implementations === Is there any support for the Firefox XPI extensions in gtkmozembed? ===No. It is not planned for the future. === Why does mfcembed crash when accessing secure sites? ===There may be multiple solutions to this problem. One possible solution is that you tried to use nss without probing it first to initialize itself.
