friends, how idea to hide or remove cvNamedWindow on openCV
i want to show video on label, but i must insert code cvNamedWindows and waitkey
but this will show windows "X"...
i want show only windows "T" not window "X" if i remove cvNamedWindow --> video on label at windows "T" not show..
thanks, sorry. i just little english
It's simple: don't call cvNamedWindow(), cvShowImage() and cvDestroyWindow().
In other words, remove all those lines from your code, but leave the call to cvWaitKey(33). This function makes the loop sleep for 33ms before the next frame is retrieved.
mmmmm...
I am not an expert GUI programmer, but I think that this is not the best way to get what you want. You are hanging forever on the callback Dialog::on_showVIDEO_clicked() which probably will leave your GUI unresponsive.
IMHO, you should move the contents of that callback to a thread, remove the calls to cvNamedWindow(), cvShowImage() and cvDestroyWindow() and change the call to cvWaitKey(33) for a usleep(33). Then inside Dialog::on_showVIDEO_clicked(), start/stop the thread as needed.
It might seem like a lot of work, but I think it is the way to go.

In the future, post the code itself, not an image of it.
