Report

Python OpenCV setWindowTitle() method used for giving the title of the windows. It takes 2 parameters that are windows name and the title that needs to be given. Both the parameters are expected to be of string type.

Syntax: cv2.setWindowTitle( winname, title ) 

Parameters:

  • winname: windows name
  • title: title we want to set for the window with the above name.

Example of Python OpenCV setWindowTitle() methods

Here we will see an example code. We have a png image of gfg logo with the name "gfg_logo.png" and for this example, we will display it on a window using imread() and imshow() methods of OpenCV. We will change the Windows title from the default name to "Hello!" using the setWindowTitle() method. We will pass the parameters windows name which is "gfg" and the title we want to set as parameters.

Python 
# importing cv2 module import cv2  # read the image img = cv2.imread("gfg_logo.png")  # showing the image cv2.imshow('gfg', img)  # Setting the windows title to "Hello!" # using setWindowTitle method cv2.setWindowTitle('gfg', 'Hello!')  # waiting using waitKey method cv2.waitKey(0)

Output:
