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: [email protected] 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!!

There isn't really much high-level documentation available. There are some basic diagrams of WebKit overall layout and WebKit/GTK+ class design in these slides: http://www.atoker.com/blog/2008/02/26/developing-hybrid-web-gtk-applications/ > > Thank you in advance!! > > Seokbae > > * P.S.

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.
