Re: [webkit-dev] Questions of WebKit Architecture
Hi, Seokbae. I think there is no official graphic engine. Moreover there is no generic WebKit or general porting layer. There are only real ports for specific platform/environments. Your choice of a port as the base depends the characteristics of your platform, I think. (Do you mean some kind of Linux? or WIPI? ^^) For API documents, you can see official documentation of Apple. It's very helpful. Of course you can see relavant sources of each ports. - joonwon - - Original Message - From: 손석배[단말개발담당] To: Alp Toker Cc: webkit-dev@lists.webkit.org Sent: Wednesday, March 26, 2008 1:31 PM Subject: Re: [webkit-dev] Questions of WebKit Architecture Thank you for your answer. It is really helpful for me. Thank you. Well, however, I still have some questions on the role of Cairo backend. As you described, Cairo is the official graphic backend of WebKit/GTK+. That means, without Cairo backend, you cannot make WebKit/GTK+ port as it is, if I understand it corrrectly. (Well, if you change the porting part, you might be able to, though) Well, however, I still have some questions on the role of Cairo backend in generic WebKit. Can we call cairo is the official graphic engine for the generic WebKit or is it just one of the options of graphic backends for WebKit? I mean, let's say I want to port generic WebKit on a platform. (A platform is not well-known platform such as windwos, linux or Mac OS. Let's say it's a proprietary, but has enough features for WebKit porting.) Then, if I port Cairo on that platform as well, does it mean I don't need to change WebKit code(or chage very little) of rendering part? In addtion to that, I have 2 more, irrelavant questions with Cairo. # Question 1 If I port WebKit on a proprietary platform, which port would you recommand for me to choose as a base? # Question 2 Are there any WebKit APIs documents available? Official one will be better, but seems like there's no officail documents on APIs, so if you can share your own notes, that would be very much appreciated. (Well, I think \WebKit has APIs. For example, Files in \WebKit\win\Interfaces are APIs for Windows port and \WebKit\mac has APIs for Mac OS, it seems. But, the numbers of APIs for each platform are not the same. And some of them look like internal APIs, not public APIs. Am I right?) Thank you for reading and answers in advance!!

Seokbae * P.S. BTW, Is cairo engine included in the WebKit? It doesn't look like so, but someone told me it is so and I'm confused.. (Well, GTK+ port assumes cairo engine, but still it is not included in the WebKit and cairo's not the official graphic engine for WebKit expcept for SVG, isn't it?) The Cairo graphics backend used for all rendering including HTML content, SVG and Canvas in the GTK+ port is in WebKit SVN. We have a summary of the code modules (complete with links to the sources) in the wiki: http://trac.webkit.org/projects/webkit/wiki/HackingGtk The actual Cairo library isn't bundled with WebKit. You can download and install this separately from http://www.cairographics.org/ You need Cairo 1.4 or newer and should ideally use the latest release.

Re: [webkit-dev] Cairo WebKit with Windows XP
Hi, Brent. I'm trying to build on Windows now. I applied your patch 17442. I failed to build Project WebKit because CGContextRef could not be converted to PlatformGraphicsContext * in the following files. ..\WebDragClient.cpp(235) : error C2664: 'WebCore::GraphicsContext::GraphicsContext(PlatformGraphicsContext *)' : ..\WebFrame.cpp(2696) : error C2664: 'CGContextSaveGState' : Did I miss something?

I have another set of patches that need to be landed as well that re- enable the Windows Theme support and provides a rudimentary scroll bar. I hope to get that posted today or tomorrow.

[webkit-dev] build problem on Windows
Hi, all. I'm trying to build the webkit on Windows(XP) and I have trouble. 1. First, I tried to follow instructions on the website. After installing Visual Studio 2005, (re-installing)Cygwin and QuickTime SDK, I checked out the code. Until now fine. But after that I can't build, because I don't have qmake. With qmake (which I got after building the whole Qt), it is said that WebKit.pro file cannot be found. -- $ WebKit/WebKitTools/Scripts/build-webkit Subroutine main::tmpfile redefined at /usr/lib/perl5/5.8/Exporter.pm line 65. at /usr/lib/perl5/5.8/cygwin/POSIX.pm line 19 Subroutine main::tmpnam redefined at /usr/lib/perl5/5.8/Exporter.pm line 65. at /usr/lib/perl5/5.8/cygwin/POSIX.pm line 19 Checking mod-date of WebKitSupportLibrary.zip...
