[webkit-dev] RenderObject hasLayer method
Hi, Can someone please tell me what does the 'layer' in a RenderObject means? in other words, what does hasLayer method returns or purpose of that method? Thank you. ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
[webkit-dev] Frame layout size
Hi: I want to scale the frame size to fit different window size. In my way , I used layoutWidth() to get the displaying size and used contentsWidth() to get the web contents truly size, but both of this values sometims are same. For example, I launch GtkLauncher to browse google, I got the correct layoutWidth and contentsWidth value at the first time. Ater then, I click on the url entry and press enter key, the page will be reloaded, but this two function will return a same value. Is it right? I'm curious about what meaning of these three functions: 1. visibleWidth() 2. layoutWidth() 3. contentsWidth() I think layoutWidth() just the visiable area width of whole window, it isn't including title, toolbar, scrollbar, border, and other things, and I think contentsWidth() is the width of web page contents. If this is right, I have a weird case. I make the window size of GtkLauncher is 480x272, but the layoutWidth() will return 510 when I browse google. It looks like not the true visiable area width. Besides, the visableWidth() is the same as layoutWidth(). If I want to get the width and height of visiable area and web page contents, does any function I can use?

RenderLayers are responsible for painting and hit testing some subset of the render tree that shares a common coordinate space, to put it simply. RenderLayers hang off of the tree of RenderObjects, and are themselves parented in parallel with their associated RenderObjects. However, we build a painting order tree of RenderObjects via their z- order lists, which controls the back-to-front painting order between RenderLayers. When painting happens, we start painting with the root RenderLayer, which paints tells any RLs behind it to paint, then paints its enclosing RenderObjects, and then tells any RLs in front of it to paint, and this continues down the RL tree. Hit testing all uses the z- order tree to do front-to-back hit testing. RenderLayers get created for elements with overflow, absolute or relative position, transforms, masks, opacity 1 and various other reasons. RenderLayers are used on all platforms, and have no platform- specific behavior. Now we do have some support in the code for accelerated compositing, and that does involve RenderLayers indirectly, but there is a much more complex relationship between a RenderLayer and associated hardware-based layers than Scott alludes to above (see the RenderLayerCompositor/RenderLayerBacking/GraphicsLayer code for that stuff).
