, the title and the body are drawn at the first layer, and the photo is at the last layer. L Jun and I also followed the process from parsing this HTML text file to generating domtree and rendering tree to understand the specific components of DOM tree and renderingtree, and the construction steps. Let's talk about domtree in the lower left corner of figure 1. Basically, each tag in an HTML text file corresponds to a class in WebKit, WebCore, and HTML

and rendering tree, aims to understand domThe specific structure and construction process of tree and rendering tree. First, let's talk about the DOM in the lower left corner of figure 1.Tree. Basically, each tag in an HTML text file corresponds to a class in WebKit, WebCore, and HTML. For example, Tag corresponds to htmlhtmlelement, Tags correspond to htmlstyleelement and so on. What's special is Dom.Tree root node, htmldocument, which does not corr

Horizon is a subproject of OpenStack that provides a Web front-end console (called a dashboard) to demonstrate the functionality of OpenStack. Usually, we start from horizon, Dashboard to understand the OpenStack.

Figure 1, a simple HTML text file is displayed on the upper left and a page drawn by WebKit rendering engine on the upper right. The page contains a title, "AI", a line of text, "ape's intelligence", and a photo. The entire page is divided into two layers, the title and the body are drawn at the first layer, and the photo is at the last layer. L Jun and I also followed the process from parsing this HTML text file to generating the DOM tree and rendering tree. The purpose is to understand the sp

2.2 Front buffers (Front buffer)drawing tiles through Qpinter is really about drawing the pixmap stored in the front buffer. A tile without a front buffer means that it does not need to be drawn.2.3 Back buffer (backend)the back buffer acts as a screen for tile content (off-screen)The back buffer and can be drawn to the QT widget using a qt brush. In the process of updating the buffer (In the process of Updatebackbuffer), for a dirty area caused by an invalid operation (invalidate), WebKit draws

. Of course, more modules can be divided if subdivided. As shown in Among them, WebCore is the core part of WebKit. It implements document modeling, including CSS, Dom, and render implementation. javasript core is obviously an implementation supported by javasript. The orange-labeled WebKit contains the implementation of WebKit encapsulation on many different platforms, that is, the implementation of some concepts that correspond directly to the

Dom is a language-independent API, its browser in the pretext is to use JS to achieve.Browsers usually implement the DOM and JS independently.In IE, the implementation name of JS is JScript, located in the Jscript.dll file, the DOM implementation is Mshtml.dll;The DOM and rendering in Safari are implemented using the WebCore in WebKit, and JS is implemented with an independent javascriptcore engine;Google Browser, also use WebKit in the
