示例1: computeRelativePosition
void MouseRelatedEvent::computeRelativePosition()
{
Node* targetNode = target() ? target()->toNode() : nullptr;
if (!targetNode)
return;
// Compute coordinates that are based on the target.
m_layerLocation = m_pageLocation;
m_offsetLocation = m_pageLocation;
// Must have an updated layout tree for this math to work correctly.
targetNode->document().updateLayoutIgnorePendingStylesheets();
// Adjust offsetLocation to be relative to the target's padding box.
if (LayoutObject* r = targetNode->layoutObject()) {
FloatPoint localPos = r->absoluteToLocal(FloatPoint(absoluteLocation()), UseTransforms);
// Adding this here to address crbug.com/570666. Basically we'd like to
// find the local coordinates relative to the padding box not the border box.
if (r->isBoxModelObject()) {
LayoutBoxModelObject* layoutBox = toLayoutBoxModelObject(r);
localPos.move(-layoutBox->borderLeft(), -layoutBox->borderTop());
}
m_offsetLocation = roundedLayoutPoint(localPos);
float scaleFactor = 1 / pageZoomFactor(this);
if (scaleFactor != 1.0f)
m_offsetLocation.scale(scaleFactor, scaleFactor);
}
// Adjust layerLocation to be relative to the layer.
// FIXME: event.layerX and event.layerY are poorly defined,
// and probably don't always correspond to PaintLayer offsets.
