C++ (Cpp) UpdateAreas Examples

Example #1

void
nsImageMap::MaybeUpdateAreas(nsIContent *aContent)
{
  if (aContent == mMap || mContainsBlockContents) {
    UpdateAreas();
  }
}

Example #2

File: nsImageMap.cpp Project: BrunoReX/palemoon

nsresult
nsImageMap::Init(nsImageFrame* aImageFrame, nsIContent* aMap)
{
  NS_PRECONDITION(aMap, "null ptr");
  if (!aMap) {
    return NS_ERROR_NULL_POINTER;
  }
  mImageFrame = aImageFrame;

  mMap = aMap;
  mMap->AddMutationObserver(this);

  // "Compile" the areas in the map into faster access versions
  return UpdateAreas();
}

Example #3

nsresult
nsImageMap::Init(nsIPresShell* aPresShell, nsIFrame* aImageFrame, nsIDOMHTMLMapElement* aMap)
{
  NS_PRECONDITION(nsnull != aMap, "null ptr");
  if (nsnull == aMap) {
    return NS_ERROR_NULL_POINTER;
  }
  mPresShell = aPresShell;
  mImageFrame = aImageFrame;

  mMap = do_QueryInterface(aMap);
  NS_ASSERTION(mMap, "aMap is not an nsIContent!");
  mMap->AddMutationObserver(this);

  // "Compile" the areas in the map into faster access versions
  return UpdateAreas();
}
