C++ (Cpp) nsRegion::RectIter Exemples

Exemple #1

Fichier : nsRegion.cpp Projet : ajkerrigan/gecko-dev

bool nsRegion::Contains(const nsRegion& aRgn) const
{
  // XXX this could be made faster by iterating over
  // both regions at the same time some how
  for (auto iter = aRgn.RectIter(); !iter.Done(); iter.Next()) {
    if (!Contains(iter.Get())) {
      return false;
    }
  }
  return true;
}

Exemple #2

Fichier : TestRegion.cpp Projet : carriercomm/gecko-dev

 void set(nsRegion &region) {
   clear();
   for (auto iter = region.RectIter(); !iter.Done(); iter.Next()) {
     const nsRect& r = iter.Get();
     for (int y = r.y; y < r.YMost(); y++) {
       for (int x = r.x; x < r.XMost(); x++) {
         bitmap[x + y * width] = REGION_VALUE;
       }
     }
   }
 }

Exemple #3

Fichier : PositionedEventTargeting.cpp Projet : rnd-user/gecko-dev

static float

{
  MOZ_ASSERT(!aRegion.IsEmpty(), "can't compute distance between point and empty region");
  float minDist = -1;
  for (auto iter = aRegion.RectIter(); !iter.Done(); iter.Next()) {
    float dist = ComputeDistanceFromRect(aPoint, iter.Get());
    if (dist < minDist || minDist < 0) {
      minDist = dist;
    }
  }
  return minDist;
}
