ttk Treeview selection_set can't accept spaces

python, treeview, ttk

Solution

You might try the following:

tree.selection_set('"Sunset Grill"')

I'm guessing this based on the code for `ttk.py` and my limited understanding of Tcl. The call to `tree.selection_set()` calls `self.selection("set", items)`, which in turn calls `self.tk.call(self._w, "selection", selop, items)` where `selop` is `'set'` and items is the string initially passed to `selection_set()`.

I'm not sure if the `self.tk.call()` is doing any massaging of the arguments before passing them to Tcl as it's a call into the `_tkinter.c module` and I don't know enough about the Python/C interface to grok that code. `;)`

Problem

I'm building a gui using tkk in python and I'm having trouble with the `Treeview` command `selection_set()`. I'm trying to use it to set the default selection when my program starts but it seems that it can't accept a string with spaces in it. ``` tree.selection_set("Sunset Grill") ``` Causes: ``` return self.tk.call(self._w, "selection", selop, items) _tkinter.TclError: Item Sunset not found ``` Can anyone give any suggestions?
