Tkinter - can't find package treectrl

问题

Well I wanted to try using multi-column ListBox in Tkinter, and I came to find "TkTreectrl" which was suggested here, but the problem is, when I try using it and creating a MultiListbox, I'm getting this error:

"_tkinter.TclError: can't find package treectrl"

Any ideas what to do? thanks!

回答1:

Download 64 or x86 bit tktreectrl (depending upon system arch) from this below link :

https://sourceforge.net/projects/tktreectrl/files/tktreectrl/tktreectrl-2.4.1/

Put it in tcl folder (e.g your conda directory where you get this error --C:\Users\<username>\AppData\Local\Continuum\miniconda3\tcl\)

You will get rid of two types of of error:

1. Can't find package error
2. Invalid argument Error
