Re: [webkit-dev] Rendering for small screen
Hi xunxin: Thanks for your reply in first. Because of I adapt the GTK+/webkit, I couldn't find same functions in GTK+ port. I found a function named FrameView::adjustViewSize which use setContentSize to set the content size. If I alter the width and height parameters, the scroll bar won't shon in browser window. But the whole page contents still overflow the window size. For example, I set the window size is 800*400, and the web page contents are 781*488. In this case, we will have a vertical scroll bar. Now I want to render the web page contents in proportion to window size, and we can see the whole page contents in the browser window. To achieve this goal, what should I do? Do I need to set the width and height for different htnl tag or there is a global variable to control it in webkit? And I have another question. I found a function named Frame::createView which has a viewportSize parameter, but I didn't know where this function be called. Do you have any suggestions? Thanks, Graffine. xunxin ??: Hi, Graffine: In QtWebKit, you may use: page-mainFrame()-setScrollBarPolicy(Qt::Horizontal, Qt::ScrollBarAlwaysOff); page-mainFrame()-setScrollBarPolicy(Qt::Vertical, Qt::ScrollBarAlwaysOff); page-setViewportSize( mainFrame-contentsSize() ); On Mon, Apr 20, 2009 at 5:21 PM, Graffine graff...@gmail.com mailto:graff...@gmail.com wrote: Hello: I want to render the web page content to small screen size.

[webkit-dev] about hashmap staticDOMObjects
hi all:
I still don't understand the purpose of the HashMap:
static DOMObjectMap domObjects()
{
// Don't use malloc here. Calling malloc from a mark function can
deadlock.
static DOMObjectMap staticDOMObjects;
return staticDOMObjects;
}
what kind of DOMObjects should be stored in it? And why?
I searched the source codes and I found that these classes below will do
that:
Document, Event, HTMLCollection, XMLHttpRequest, CanvasGradient,
CanvasPattern, CanvasRenderingContext2D, DOMCoreException,
DOMImplementation, DOMParser, EventException, History, NamedNodeMap,
NodeFilter, NodeIterator, NodeList, Range, RangeException, TreeWalker,
XMLHttpRequestException, XMLSerializer, Clipboard
but what's the reason? Is it because these classes are essentially simple
and just acting as a tool?
thanks a lot

Re: [webkit-dev] about hashmap staticDOMObjects
oh, I got an idea:
Is it because these domobjects doesn't belong to a Document, so they can't
be

[webkit-dev] print file name and line number while executing javascript
Hi, I'm working a very specific platform built on top of Mac OS X. On my own platform I need to use WebKit. In order to have WebKit, I've redone my own webkit framework (in c++) and my own webkit uses webcore framework (almost unchanged) and javascxript core (totally unchanged). Everything works... almost... I can even display the google map in my own platform. I can zoom in, move the map. The only bug is as soon as I resize my window, the google map becomes gray. According to my tests (using innerHTML), the javascript from google doesn't produce the right html. So it doesn't seem to be a display problem. I suspect some javascript events are not triggered or may too much javascript events are triggered, and then the google map code is confused. So my question is : Is there a way to do printf in javascript core, somewhere, to display all the javascript command executed and also to display the file name and the line number where they are? To solve my problem I wish to compare a google map being resized using the regular webkit (in objective-c for appkit) with my own webkit (in c++ for my platform).

[webkit-dev] Writing a new interface, hit a snag
Greetings all... I have spent the last few weeks writing what is effectively a null interface, so I can use WebKit as a backend system for retrieving webpages on a headless X11-less gtk-less machine. This isnt for spamming, mail harvesting or other nefarious activities, dont worry :-) It's so we can process certain requests from our website so when people go there, it looks like an integrated system instead of a half dozen disparate packages! So, I have an issue that I have been pulling my hair out on for over a week now, Ive been single stepping through code for days trying to find what can cause this. The entire null interface works fine, as long as Javascript is turned off. It loads all the items it needs and I can access them. Great, just what I needed. As soon as Javascript is turned on, it blows up. Now, Ive been coding for a LONG time and Ive never seen an error from gdb quite like this... #0 0x00e6ee37 in ctiTrampoline () from /home/michael/webkit_rejig/webkit/.libs/libwebkit-1.0.so.1 #1 0xb7fd4b40 in ??

So, it seems that it crashes while loading ctiTrampoline, but this is an asm routine (I dont know asm) and so the error could be in the call() that it makes within this function. Now, I am assuming that the error is that I have stubbed or missed something in the GTK handler when porting to the null handler. Some initialisation call to something in the Javascript engine, I honestly don't know. I am hoping that this mail reaches someone who knows the js engine inside out and can say 'ohhh yeah thats cos you missed X' and then I can go do X :-) Crossed fingers Michael ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

I use MIPS32EL, VA_LIST call, MIPS pushes function argument
from left to right. I wrote a simple VA_LIST test it works
on my box.
BEGIN_STUB_FUNCTION() cause seg fault due to MIPS uses gp
reg to read sth.
I treied to rewrite the code like that:
JSObject* JITStubs::cti_op_new_func_exp(STUB_ARGS)
{
va_list vl_args;
va_start(vl_args, args);
StackHack stackHack(STUB_RETURN_ADDRESS_SLOT);
JSValuePtr dividendValue = va_arg(vl_args, JSC::JSCell*
);
JSValuePtr divisorValue = va_arg(vl_args, JSC::JSCell*
);
...
}
Still fail in stackHack(), if I comment out stackHack()
then fails at va_arg.
gp is a global register for common/public variables, the
same usage before I call cti_op_mod() works fine.
I also tried not use VA_LIST but REGISTER calling
convention, still fail:

That's an excellent point about HTTP auth.

[webkit-dev] Using DocLoader vs SubresourceLoader for loading a (worker) script
You're basically switching from DocLoader to SubresourceLoader for loading a script for workers. DocLoader uses CachedResource and SubresourceLoader doesn't. So another way to state your question is: - What benefit does one get from using the cache (CachedResource) for loading worker scripts? - If one switched to using SubresourceLoader, is it useful or necessary to add support (under a flag) for CachedResource to SubresourceLoader?

Following up on this - is using a dialog for HTTP auth for worker requests really such a bad thing? What if we only do this as a fallback, in the case that the initiating window is closed?

I use MIPS32EL, VA_LIST call, MIPS pushes function argument
from left to right. I wrote a simple VA_LIST test it works
on my box.
BEGIN_STUB_FUNCTION() cause seg fault due to MIPS uses gp
reg to read sth.
I treied to rewrite the code like that:
JSObject* JITStubs::cti_op_new_func_exp(STUB_ARGS)
{
va_list vl_args;
va_start(vl_args, args);
StackHack stackHack(STUB_RETURN_ADDRESS_SLOT);
JSValuePtr dividendValue = va_arg(vl_args, JSC::JSCell*
);
JSValuePtr divisorValue = va_arg(vl_args, JSC::JSCell*
);
...
}
Still fail in stackHack(), if I comment out stackHack()
then fails at va_arg.
gp is a global register for common/public variables, the
same usage before I call cti_op_mod() works fine.
I also tried not use VA_LIST but REGISTER calling
convention, still fail:

Re: [webkit-dev] drag'n'drop file uploads
Does anyone have any pointers on drag and drop files from the finder directly into a web page or section of a web page. I've got examples in Firefox for this but sadly lacking in WebKit knowledge. Maybe if you pointed to the examples “in Firefox” we could get a better idea of what you’re talking about. If they are based on web standards and don’t depend on Firefox-specific features, then there’s a good chance they can be made to work in WebKit-based browsers as well. Perhaps there are bugs getting in the way. -- Darin Unfortunately the Firefox version uses the XPConnect bridge to get permissions handling and the XPCOM for the low level stuff. Here is a link to the source: http://straxus.javadevelopersjournal.com/creating_a_mozillafirefox_drag_and_drop_file_upload_script_p.htm I'm looking to create web applications in HTML5 and CSS3.0 that allow a user to drag either individual files or a folder of files into the application and are then manipulated and stored with reference to the actual files in the database. Once completed all files are then fired off to the server to final composition. I remember looking into this a while ago and finally gave up, only now we actually could really do with the ease of use and was hoping the Webkit nightly builds could have helped to provide the goods.

hi all:
I still don't understand the purpose of the HashMap:
static DOMObjectMap domObjects()
{
// Don't use malloc here. Calling malloc from a mark function
can deadlock.
static DOMObjectMap staticDOMObjects;
return staticDOMObjects;
}
what kind of DOMObjects should be stored in it? And why?
I searched the source codes and I found that these classes below
will do that:
Document, Event, HTMLCollection, XMLHttpRequest, CanvasGradient,
CanvasPattern, CanvasRenderingContext2D, DOMCoreException,
DOMImplementation, DOMParser, EventException, History, NamedNodeMap,
NodeFilter, NodeIterator, NodeList, Range, RangeException,
TreeWalker, XMLHttpRequestException, XMLSerializer, Clipboard
but what's the reason? Is it because these classes are essentially
simple and just acting as a tool?
The hash map is to ensure that DOM wrappers are unique but created on
demand, without consuming a pointer in the underlying C++ object. For
DOM Nodes, we use a hash table in the Node's owner document, but in
the case of non-Node objects and the Document itself (which has no
owner document), we need this global hash table.

Re: [webkit-dev] SharedWorker design doc
That's also a reasonable option - so we'd just return a 401 error to the caller if the initiating window is unable to gather credentials. -atw 2009/4/22 Maciej Stachowiak m...@apple.com On Apr 22, 2009, at 11:54 AM, Drew Wilson wrote: Following up on this - is using a dialog for HTTP auth for worker requests really such a bad thing?

[webkit-dev] How to make the size of QtWebKit4.dll or libQtWetKit.so smaller?
Hi all: I found that the qt-win-opensource-4.5.0-mingw.exe source code to build qt with webkit under windows, and found the release version size is following: QtCore4.dll 2.61M QtGui4.dll 10.9M QtNetwork4.dll 1.32M QtWebKit4.dll 18.8M But I installed the qt-sdk-win-opensource-2009.01.1.exe provided by official site. And I found the dlls are smaller than that I builded. QtCore4.dll 1.97M QtGui4.dll 7.14M QtNetwork4.dll 852K QtWebKit4.dll 8M Why so different on the size, Whether there are some other compile options to be set? Anyone know how to get smaller WebKit library? We want to use it in a Embedded environment. -- alex ding Email:bupt...@163.com msn:bupt...@msn.com ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] drag'n'drop file uploads
You can drag and drop a file onto the file input control, which you can create using input type=file. I'm not sure if that addresses your use case.
