How to check if an opencv window is closed

Question

How do you check if an opencv window has been closed?

I would like to do:

cvNamedWindow(\"main\", 1);

while(!cvWindowIsClosed(\"main\"))
{
    cvSho         


        

Answer 1

This should do

#include 

std::string mTitle = "title of my window";

while (cvGetWindowHandle(mTitle.c_str()))
{
   // ...
}
