How to capture mouse click events in Python?

How to capture mouse click events in Python?

In this example we’ll click and drag a rectangular Region of Interest (ROI) and crop it from our image. This technique is especially helpful if you are labeling data as input to an image classification algorithm. So if you’re trying to understand how mouse click events work with Python and OpenCV, then look no further!

How to add a map to a Python toolbar?

Install the Python Add-in Wizard and start a project. Go through the wizard to create a new toolbar and a subsequent new tool. Open the Python script that is generated for the add-in and find the tool class that was added in Step 1. The function ‘onMouseDownMap’ passes the map’s coordinates to the add-in.
