There is a method on RenderObject to get the correct absolute coordinates of
the renderer, which correctly takes transforms, scrolling etc into account:
RenderObject::localToAbsolute(). This is not a trivial problem.
localToAbsolute() is only fragile because if you are querying for
the position of a renderobject inside an iframe, it is not relative to
mainFrame but to the currentFrame. I've done it like below:
static inline IntRect absoluteRenderRect(RenderObject* render)
{
ASSERT(render);
// FIXME: This function is flawed because it doesn't consider the
effects of CSS or SVG transforms.
IntRect rect(render-absoluteClippedOverflowRect());
// handle nested frames.
for (Frame* frame = render-document()-frame(); frame; frame =
frame-tree()-parent())
if(HTMLFrameOwnerElement* ownerElement = frame-ownerElement())
rect.move(ownerElement-renderer()-offsetLeft(),
ownerElement-renderer()-offsetTop());
return rect;
}
maybe there is a better way , but ...
Hi, I have tried using the dumpRenderTree to dump out the absolute
co-ordinates of the
Render Tree of www.google.com. I put the absolute x, y result at the
end marked by { and }.
And www.google.com, the first text is 'Web followed by Images
followed by Video followed by Maps.
But what I don't understand is (from the output below) is all the
absolute coordinates of those text are x = 8.0 and y = 3.0. But
visually, they are next to each other horizontally. So the y values
should be the same but the x values should be different. Can you
please help me understand the result? And there is no iframe problem
the like you described.
Thank you.
Here is the output:
