Python OpenCV - remove title bar, toolbar, and status bar

Question

I\'ve found documentation regarding C ++, but not much with python.

The basic code to display in python is:

import numpy as np
import cv2

# Load an          


        

Answer 1

Did a little more looking around:

using these flags is how to do it with QT backend.

CV_GUI_NORMAL or CV_GUI_EXPANDED: CV_GUI_NORMAL is the old way to draw the window without statusbar and toolbar, whereas CV_GUI_EXPANDED is a new enhanced GUI.

unfortunetly, cv2.namedWindow('image', flags=cv2.CV_GUI_EXPANDED) does not work, even though I'm pretty sure I have QT backend (actually I'm positive I do).

After looking up help(cv2), I found similar flags WINDOW_GUI_EXPANDED and WINDOW_GUI_NORMAL. So use those.

img = cv2.imread('messi.jpg',0)

# Removes toolbar and status bar
cv2.namedWindow('image', flags=cv2.WINDOW_GUI_NORMAL)

cv2.imshow('image',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

But still having trouble trying to remove the title bar.
