Fullscreen Causes AttributeError in Python OpenCV

Question

This is an odd little thing. I'm using OpenCV 2.4.2 (brew build on OSX 10.7), cv2 bindings, and going by the OpenCV documentation, I've tried both:

cv2.setWindowProperty("Image", cv2.WND_PROP_FULLSCREEN, cv2.WINDOW_FULLSCREEN)
cv2.setWindowProperty("Image", cv2.CV_WND_PROP_FULLSCREEN, cv2.CV_WINDOW_FULLSCREEN)

Both return that cv2 doesn't have this attribute. I assume they just haven't been added to the cv2 bindings yet. Is there a way to get around this?

As you can see there's only cv2.CV_WINDOW_AUTOSIZE attribute available. To use FULLSIZE attribute, you need to use cv2.cvmodule.

cv2.setWindowProperty("Image", cv2.WND_PROP_FULLSCREEN, cv2.cv.CV_WINDOW_FULLSCREEN)

Mostly right, though there was one small edit to your answer. Instead of cv2.cv.WINDOW_FULLSCREEN, I needed cv2.cv.CV_WINDOW_FULLSCREEN. Where in the documentation did you find this and how do you see which attributes are actually available?

I use IPython, so when you press tab button, it shows all the available attributes.
