Matlab and cvNamedWindow of OpenCV

Question

I'm working with OpenCV programs in C++ and calling them in Matlab using calllib.

The thing is that when the program exits the cvNamedWindows does not close.

I've tried DestroyWindow and DestroyAllWindows but inside Matlab it won't close.

Here is some code

int main()
{
  int device = 0;
  vCap = VideoCapture( device );

  Mat img;
  vCap >> img;

  imshow("colour", img);
  cv::waitKey(1);

  namedWindow("colour",1);
  cv::destroyWindow("colour");
  return 0;
}

This is C++ code. I don't understand what you are trying to do with this and `calllib`. If you want to use opencv in Matlab, have a look to this [mexfile](https://github.com/kyamagu/mexopencv) — Vuwox, May 27 '14 at 20:21

`cvStartWindowThread();` works if I have only one named window opened. — SamuelNLP, May 28 '14 at 17:24
If you create multiple window, did you use `destroyWindow(Name)`? or `destroyAll()` ? — Vuwox, May 28 '14 at 17:44
