How to Install and Use TkDnD with Python Tkinter on OSX?

Question

I\'ve spent some time to search for workable solution to do Drag and Drop behavior with Python Tkinter on OSX platform, and the most possible solution found is TkDnD library

Answer 1

This is an update from 2020 for MacOS Catalina users.

Firstly, the tkdnd library project has been moved to github. The latest version is 2.9.3, and if you do not want to compile the library yourself the latest release is 2.9.2.

Secondly, placing the tkdnd lib on /Library/Tcl doesn't work anymore (you will get "error: tkdnd library not found"). With Catalina, python looks for the tkdnd lib in its own folder, that is /Library/Frameworks/Python.framework/Versions/.../lib. Placing the tkdnd2.9.3 folder in this path works just fine.

By the way, placing the TkinterDnD2 Python wrapper in /Library/Frameworks/Python.framework/Versions/.../lib/python/site-packages still works on Catalina.

Just to clarify, I only tested it for Python 3 (3.8.5), I do not know if for Python 2 the solution is the same but I suppose so.
