[webkit-dev] How does webkit keep track of co-ordinates/dimension of each line of text in a Paragraph tag?
Hi, Can you please tell me how does webkit keep track of co-ordinates/dimension of each line of text in a Paragraph tag? For example, if I have a Paragraph of text. Web kit will split it up into multiple lines of text. How does webkit (what data-structure it uses) to keep track of each line of text within that Paragraph? Thank you. ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

Check out InlineTextBox in the rendering directory. dave On Mar 29, 2009, at 5:40 PM, ying lcs wrote: Hi, Can you please tell me how does webkit keep track of co-ordinates/dimension of each line of text in a Paragraph tag?

[webkit-dev] Cocoa WebView and the Web Inspector
I've seen references indicating that it is possible to use the web inspector from WebView instances in Cocoa apps. How does one go about instantiating the web inspector on a WebView instance from a Cocoa app? The reference I'm referring to is here: http://lists.macosforge.org/pipermail/webkit-dev/2007-December/003043.html ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] ［GTK］Scroll deficiency
Brent, I just start to resolve the problem. The debug build and background color hack you mentioned, i also need time to try. Please wait a reply. I hope the member in the mail-list to join in the work, when see the subject if you have the same symptom. Thanks. -Xiong On Fri, Mar 27, 2009 at 1:54 PM, Brent Fulgham bfulg...@gmail.com wrote: Xiong, I'm sorry you are encountering the problem, but I must admit I am glad someone else is seeing this issue as now we can pool our efforts to resolve it. Since you are using directfb stuff, and I am on top of Windows, it seems the culprit is somewhere in the Cairo logic. Perhaps the dirty regions are not being computed properly (I have encountered a few places where the coordinate systems in Cairo and Windows don't agree). However, the kludge of setting a background color (does this work for you as well?) does not fit into the 'bad coordinate' theory, as I don't see how the presence of a background color in the rendering instructions would affect this. The fact that it does not happen for me in Debug builds makes me wonder if maybe there is some kind of improper initialization or buffer overrun that is involved. -Brent On Mar 26, 2009, at 10:48 PM, xiong wrote: Webkit r40777 Release builds for me.

If you have questions about a version of WebKit that is not built directly from the webkit.org sources, such as that Android uses, you'll have much better luck asking the maintainers of that port questions about it since they're the ones that know exactly which version of WebKit they have and what modifications they may have made. Failing that, it would be polite to at least mention that you're not asking about the mainstream version of WebKit in order to avoid wasting people's time.

Brent, In my platform, all the hack as you metioned are valueless. Bad news to me. Now, i only have a clue on cario for the scroll problem.
