According to the documentation for the Tcl version of Tix, it's possible to use selection_clear() to deselect individual entries, as opposed to the entire selection. The documentation says the following:
pathName selection clear ?from? ?to?
When no extra arguments are given, deselects all of the list entrie(s) in this HList widget. When only from is given, only the list entry identified by from is deselected. When both from and to are given, deselects all of the list entrie(s) between between from and to, inclusive, without affecting the selection state of entries outside that range.
However, I can't for the life of me figure out how to get this functionality in Python. You'd think that you could just pass in "from" and "to" as individual arguments, but you'd be wrong -- the Python version of selection_clear() has the form: selection_clear(self, cnf={}, **kw) . It expects a dictionary and/or a keyword list. And I can't figure out the right syntax for that "from-to" thing. Can anyone help please?
Because from is a reserved word in python the Tkinter spelling of it is usually _from (note the leading underscore) this is true of standard Tkinter widgets not sure about Tix (don't use it)
For more on keyword arguments see the online docs:-
