示例1: nodeFromPoint
Node* nodeFromPoint(Document* document, int x, int y, LayoutPoint* localPoint)
{
Frame* frame = document->frame();
if (!frame)
return nullptr;
FrameView* frameView = frame->view();
if (!frameView)
return nullptr;
float scaleFactor = frame->pageZoomFactor() * frame->frameScaleFactor();
IntPoint scrollPosition = frameView->contentsScrollPosition();
IntPoint point = roundedIntPoint(FloatPoint(x * scaleFactor + scrollPosition.x(), y * scaleFactor + scrollPosition.y()));
IntRect visibleRect;
#if PLATFORM(IOS)
visibleRect = frameView->unobscuredContentRect();
#else
visibleRect = frameView->visibleContentRect();
#endif
if (!visibleRect.contains(point))
return nullptr;
HitTestRequest request(HitTestRequest::ReadOnly | HitTestRequest::Active | HitTestRequest::DisallowShadowContent);
HitTestResult result(point);
document->renderView()->hitTest(request, result);
if (localPoint)
*localPoint = result.localPoint();
return result.innerNode();
