HitTest can also help here, probably. APIs for it are port dependent, iirc. On Wed, Aug 12, 2009 at 3:41 AM, Eric Seidel<eric@webkit.org> wrote:

Hi:

I'm trying to figure out the DOM element at a certain (x,y) point. To do this I'm using Document::prepareMouseEvent() which seems to return what I expect - most of the time. Specifically <input type="text"> nodes are returned as <div>#text</div>. It appears to me as though I'm getting the internal representation of the text input element. How can I get the "real" element at a given location?

Thanks.

This is really a question for the webkit-help list. The solution is to call getComputedStyle(). Simon On Aug 12, 2009, at 8:52 AM, TianShijun wrote:

How can i get the background-image url of an element node?

Usually, I can read the "background-image" attribute of the node. But if it is written in the style sheet, there is no explicit "background-image" attribute in the element's attributes list. Instead, there is a "class" attribute.

I have also tried to get some information from RenderStyle. But it can only provide an interface hasBackgroundImage() .

How can I get it? It seems not to be an elegant way that we firstly read the style class abtribute and then parse the style sheet file. Could WebKit provides an expandedAttributes() interface which can return all the attributes by simply expanding the class attribute with those written in the style sheet?

Hi Simon, I cannot find this method in either Node.h or RenderStyle.h. I wonder that why we cannot get the attribute of an element node just by invoking some member function of the node?

Line 440 of Node.h virtual RenderStyle* computedStyle(); This gives you renderStyle. If you do position.computedStyle(), you'll obtain CSSComputedStyleDeclaration. A node could be anything, so you need to first check whether it's an HTML element or not. You can do so by calling node->isElementNode(). Once node->isElementNode() returned, true, you cast the node into Element and call getAttribute there as in: static_cast<Element*>(node)->getAttribute(qualifiedName) *Please post the questions like this on webkit-help.* Ryosuke
