[Tkinter-discuss] Tix question [possibly off-topic]

[Jeff Epler]

Tix support in Python comes in two parts:  First, the Tix Python module,
which is just an object-oriented wrapper.  Second, the Tix package for
tcl.  The error you got indicates that the Tix package for tcl is not
installed.

On my system (Ubuntu 5.10), installing the debian package 'tix8.1'
allowed your example script to execute successfully.
