  For input elements, I would just tune the QStyle of the view.

  I would know if I can do the web-based application with Qt-WebKit and detect when connection fall down, then launch automatically, and transparent for the user, the client application made with Qt too.
  [/quote]

  Yep, it is possible. You might have to detect the disconnection yourself and propagate it to the web sandbox but that is not a big deal.

  Quite a few application for embedded are made just like that actually.

  Is it easy or could be expensive/hard?
  [/quote]

  It is easy if you know C++.

  The one thing I don't know is the state of the port for Windows Mobile, especially now that Microsoft is killing the product. I work mainly on Linux embedded.

  You should ask on the forum "Mobile and Embedded" if Windows Mobile support is still active.

  [quote author="ndovp04" date="1290014931"]Sorry for not being cleared. During the NPAPI windowless plugin process which eventually the NPP_SetWindow(NPP instance, NPWindow* window) will be invoked (in this case WebKit backend) to pass to the client plugin the window object. I like to know the NPWindow* should be casted to which QT object? I can't find any documentation about this.[/quote]

  It looks like its null, and the rendering surface is passed via the expose events. You can check PluginViewQt.cpp to get the details, I don't know much about the implementation.

  QtWebKit plugins: Deletion and hiding

  Here is a code example.
  @QObject *WebPage::createPlugin(
  const QString &classid,
  const QUrl &url,
  const QStringList &paramNames,
  const QStringList & paramValues)
  {
  QWebView *view = new QWebView();
  view->load(QUrl("http://developer.qt.nokia.com/"));
  mainFrame()->addToJavaScriptWindowObject("renderer", view);
  return view;
  }@
  With a complex workaround embedding QWebViews into iframes I get the QWebView not to be deleted, but now the QWebViews shown in first plane, so them overlap and I cannot view all the QWebViews, only the last inserted.
  I cannot refuse to use a QWebView because an iframe does not offer the isolation that I want.
  Thanks for paying attention on my problem :)

  Alright tested out this morning on Mac OS X.

  Using Cocoa: flash does not run at all. As expected after reading your blog post.

  Using Carbon: it works fine in both QWebView / QGraphicsWebView. So it appears to be something specific to Windows (Vista ?).

  Using Carbon on HTML 5: I get the exact same issues than on Windows PC, so I guess Phonon behave consistently :).

  Anyone can try running a simple QGraphicsWebView + "this url":http://www.happyworm.com/jquery/jplayer/latest/demo-02-nativeSupportFalse.htm on a Windows platform to double check it does not work ?

  Thanks.

  Please check the bug report, I asked you a question there. :)

  [quote author="HaykG" date="1287321858"]Also if possible could you please give some example/documentation of using that "platform plugin interface", because it would be the ideal case for me:)[/quote]

  There is not doc yet, this is still a feature in development. The idea is that platforms could provide some very specific implementations of features. In the case of combobox for example, you typically don't want them with touch interfaces, you want a fullscreen selection box for a better user interface (like on Maemo 5).

  You'll find the platform plugin interfaces here: "http://gitorious.org/webkit/webkit/blobs/master/WebKit/qt/Api/qwebkitplatformplugin.h":http://gitorious.org/webkit/webkit/blobs/master/WebKit/qt/Api/qwebkitplatformplugin.h

  The flag QPainter::SmoothPixmapTransform only affects the way QGraphicsItem are transformed. For WebKit, this applies for AcceleratedCompositing, but not for regular transformed layers.

  QtWebKit 2.0 did not have antialiasing for transform. This has been enabled in QtWebKit 2.1. I suggest you to try with the branch 2.1 of WebKit to have high quality transforms.

  bq. it’s better to find how Qt now supports conversion between some build-in types, for example – QString – I don’t know how it was done.

  Here is the code:

  You should not use QWebView, and especially not the zoomFactor() for touch based browsing.

  We have not had the time to do proper documentation about it but touch-based browsing is quite different from the regular browsing.

  For touch-based browsing, you generally use this:

  QGraphicsWebView Frame flattening Tiling zoom by scaling the QGraphicsWebView

  Some more info there:

  "http://gitorious.org/light":http://gitorious.org/light : basic browser for touch screen "http://gitorious.org/yberbrowser":http://gitorious.org/yberbrowser : an interesting browser for the N900 "https://bugs.webkit.org/show_bug.cgi?id=41465":https://bugs.webkit.org/show_bug.cgi?id=41465 the bug report about improving the documentation regarding those feature. A first patch is already available.

  Feel free to comment on bugzilla if you have ideas to improve the documentation further. If you have more questions, do not hesitate to ask them here on the forum.

  If the flash players sends any kind of event you can get from JavaScript, you could add a C++ object to the context and add an event listener calling that object.

  bq. WebBrowser’s (C#) WebBrowserProgressChangedEvent sends to me the signal (-1), when the flash player has just finished his job

  How does that work? You receive the event when the content has finished playing? or finished loading? I guess you could subclass QNetworkAccessManager and wait for all request to be finished.

  Cool, I am glad to know it is fixed. :)

  Thinking about it, if you have linking error with WebKit but you don't use WebKit in your project, you can add -no-webkit to configure. That will speed-up the build, and avoid you the problems.

  The issue has been solved after analysis the network packet.

  The server ONLY redirects exe link to other address and I didn't check the reply code.

  Now the reply code from server has been checked in case of any redirection and the exe file could be downloaded as well as other types.

  But I still has the question, I didn't handle redirection before, why it worked on some machines?

  I don't see any reason why the style isn't called.

  Here is the code coding the style from WebKit: p.drawComplexControl(QStyle::CC_ComboBox, opt); (RenderThemeQt::paintMenuList() in RenderThemeQt.cpp).

  Try setting a breakpoint there to investigate.

  The property -webkit-font-smoothing is a very special case. It has been introduced by Apple and is only used by them (for both their Mac and Windows port). All the other ports ignore this parameter.

  They are obviously not exported by default but you can expose any QObject to WebKit.

  For non-gui object, you simply add them with QWebFrame::addToJavaScriptWindowObject(). There are some great hybrid applications (WebKit + C++) build like that.

  To embed graphical content, it is a bit more tricky, you need to make you own QWebPluginFactory.

  I don't think you can do that directly. A work around would be to extract the content with QWebElement, but then the matching between plugins and content becomes tricky.

  Altough 4.7 compiles with VS2010, I can only advice against VS2010 at the time, especially on 64 bits. This compiler has some serious bugs like the missalignment of SSE vectors. Microsoft should fix them in the coming weeks, it is safer to use vs2008 for now.
