Manually creating a qt label to display a video stream

[kcsin]

I have a multithreaded opencv/opengl project built in a qt envirionment NO GUI :(

I'm using the opengl idle process to drive when I grab the next video frame.
The problem I'm having is this is a command line project and I need to create a QLabel when I start the display thread.

I get the label being created but it's not being updated.
You might be able to tell I have very little qt experience.

Essentially I have a separate thread that picks up a copy of an image and displays it. However, when this thread is started it needs to create a new label to display the converted image.

videoDisplay.setPixmap(QPixmap::fromImage(videoIma ge));
