TkinterDnD is a python wrapper for George Petasis' tkDnD Tk extension.
tkDnD adds native drag and drop support for windows and (yet partially) unix and Mac OSX to Tk. TkinterDnD makes this functionality available for Python/Tkinter.
Thank you for providing TkinterDnD2. I tried to import TkinterDnD2 into python 3.3 on windows8. I used 2to3 script, and changed "Tkinter.StringType" to "bytes". Now, test.py looks like working on my python 3.3. Thank you.
