This looks a bit odd this way. Maybe we should move the code in hideHighlight() to a new invalidateView(inspectedView) method and call this new function is both highlight() and hideHighlight()? This would be more understandable for me.

I would create this as late as possible, that is to say: after the NULL page check.

page->mainFrame()->view()->invalidateRect(WebCore::IntRect(0, 0, width, height)); ?

page->inspectorController() cannot return NULL so the first check is not needed. Use an ASSERT() instead if you want to be safe.

I will fix all things you mentioned. Thanks for reviewing.

I don't think invalidateView() needs to be public. I would have just used a static function in the cpp file.

EFL port has used ENABLE(...) below regular include list.

Please see ewk_view.cpp.

It makes sense.

The rest looks good.

I wonder if page always has inspector controller. If not, I think below condition is good to avoid crash.

if (WebCore::InspectorController* controller = page->inspectorController())
    if (controller->highlightedNode())
        controller->drawHighlight(*context->graphicContext);

It seems to me that page always has inspectorController.
