Priority: Low
Type: Documentation issue

Some of the Tkinter documentation is incomplete. I've only checked it on the Listbox so far, but some of the valid keyword arguments are missing. The one I noticed was "disabledforeground" which changes how the foreground color of text when the Listbox is in the disabled state or has a selection mode of none. I've noticed this across multiple versions of python, including Python 2.7 and Python 3.6, both of which accepted "disabledforeground" as a valid keyword without it being in the list shown in the help for Listbox.__init__

I found the disabledforeground keyword argument when looking at the Listbox documentation here: https://www.tcl.tk/man/tcl8.4/TkCmd/listbox.htm
