Show multiple (2,3,4,…) images in the same window in OpenCV

Question

I want to show 2, 3 or more images in the same window.

My problem is how to put the second, third image just on the right side (above, left or upper) the main image.

The GUI included with OpenCV is pretty limited, if you need to do anything complicated, you really should use a GUi framework such as QT or VC++ on windows
