[webkit-dev] Can any one enlight me on this matter; linking problem?
Hi ! When building webkit(gtk) on the maemo platform (i.e. in then Scratchbox ARMEL ) I get the following linking problem: ./.libs/libWebCore.a(libWebCore_la-StyleTransformData.o):(.bss._ZZN7WebC ore11RenderStyle16initialTransformEvE4tops[*WebCore::RenderStyle::initia lTransform()::ops]+0x0): multiple definition of `WebCore::RenderStyle::initialTransform()::tops' ./.libs/libWebCore.a(libWebCore_la-CSSStyleSelector.o):(.bss._ZZN7WebCor e11RenderStyle16initialTransformEvE4tops[WebCore::RenderStyle::initialTr ansform()::ops]+0x0): first defined here When I build on my ubuntu for (gtk) it works fine The version is the latest, but I have had the problem at least last week as well. Does anyone knows the source of problem or could direct me in some direction (tool chain versions?)

[webkit-dev] Equivalent of WebKit/Qt's link delegation policy in WebKit/Gtk+?
Hi, I'm trying to work with the GTK+ WebKit from svn/trunk to do rendering for my application. Unfortunately, I'm having some troubles. Unlike the majority of users, I don't need WebKit to access URIs on the Internet. I need to be able to intercept them and display custom HTML content to allow navigation of some complex, in-memory data structures. I thought you might be able to do something with the navigation-requested signal, but this doesn't appear to allow you to substitute content for the URI. In digging around in the source tree, I discovered that the Qt port allows you to get the linkClicked signal, provided you've registered the appropriate link delegation policy with the WebView. Is this functionality planned for the GTK+ version? Is someone currently working on implementing it? If the answers to this are no, does anyone have any pointers for how to implement something similar for the Gtk+ version? I'm not used to the Qt syntax, so I can't find the code where it interacts with the core WebKit classes to accomplish this functionality. I'd be willing to give this a go or at least help someone who is working on this, as it is essential for what I'm doing and my only other alternative is to use the soon-to-be-unmaintained GtkHTML(3) from Gnome svn. Any information on how this sort of behavior can be accomplished with the existing GTK+ api would also be welcome. Thanks in advance, ast -- Andrew S.

Hi Dave, On Thu, Oct 16, 2008 at 7:26 AM, David Kilzer [EMAIL PROTECTED] wrote: How are you forcing layout? If you're calling a method on a WebView object, then you're using non-public API and, as I mentioned earlier, your application may crash or hang. If you just need a way to force layout in JavaScript, this may be done by executing this statement: document.body.offsetTop; It seems that solved the issue :-) Many thanks, and I applaud you.

Re: [webkit-dev] webkit core need to be cleanly separated from ports, behind a vector table
While a COM or similar interface may result in a library which makes
porting easiest for new platforms, it sometimes can be harder to
develop and maintain. We've been there and I can say that in some cases
a COM-like interface really is nice to work with; and in other cases it
is perhaps too problematic to maintain. The Mozilla people initially
went a little overboard with this and decided it would be better to
scale it back somewhat.
For me, while it would be nice if everything could fit into a plug-in
interface, in the short run I would be happy if platform-specific
functionality was sometimes handled less by ifdefs within the code and
more via some kind of platform or environment abstraction. Here's an
example; in _javascript_Core/kjs/Shell.cpp there is this:
void StopWatch::start()
{
#if PLATFORM(QT)
QDateTime t = QDateTime::currentDateTime();
m_startTime = t.toTime_t() * 1000 + t.time().msec();
#elif PLATFORM(WIN_OS)
m_startTime = timeGetTime();
#else
gettimeofday(m_startTime, 0);
#endif
}
For me to add a new platform I need to edit this file and do an
integration whenever the devline WebKit version of it changes. It would
be nice if the code instead looked like this:
void StopWatch::start()
{
m_startTime = platformTimeMs(); // The back-end of this is
specified per platform.
}
Yes you could call platformTimeMs() via a function table or COM
interface, but for a lot of people it would suffice if it was simply
implemented in a platform-specific source directory.

what is there about, for example, the apache2 vector table system,
where you fill in 28 or so functions in a vector table and hand it back
to the apache runtime, that makes refactoring and redesign difficult?
extensions to the table can be done by having a union of structs,
with an int at the beginning of the table saying "i'm a version 1"
or "i'm a version 2".
then, if you have a "version 1"-using-port that connects to a "version 2"
library, the extra functions that differ from version 1 and 2 will be NULL;
the version 2 webkit library will go "oh, these are NULL, so we're not
providing version 2 functionality".
You seem to be reinventing COM.
While there are certainly parts of WebCore and WebKit as a whole where
some well-chosen interfaces would indeed make it easier to develop and
maintain additional platforms and extensions (example: dave hyatt's
recent refactoring of ScrollView and friends), I'm not sure that a
large C-style vector of function pointers for all of WebKit is an
effective way to accomplish this.
far from making it _more_ difficult to do a redesign, such techniques
would make it _easier_ i believe.
Do you have a proof of concept? Comparing approaches is always easier
with a concrete example than with abstract descriptions.
If nothing else, that would help validate your assertion that it would
be easy to implement this way :-).

Re: [webkit-dev] how can I callback javascript function from webkit engine?
Hi Alp Toker I am involved in porting webkit. I was testing a .js file with some callback. The file parsing is success and the script is executing fine. But when I press some key the function in the .js file should be invoked. But it wasnt working.

Hi, If you're using a WebView-style port (Mac, Win, GTK+) you can access the the JSGlobalContextRef holding the global object/state and JSObjectRef representing the frame's JavaScript window object with the window-object-cleared signal/callback/event, which is raised in preparation for a new load. You can also access the JSGlobalContextRef at other times using webkit_web_frame_get_global_context() / WebFrame::globalContext() or similar. Once you have these objects, you can use the standard portable JavaScriptCore API documented here: http://developer.apple.com/documentation/Carbon/Reference/WebKit_JavaScriptC ore_Ref/index.html I'm planning to write a tutorial on this since it's a frequently asked question.
