Maybe you simply confuse Button-2 (the button in the middle, under the
wheel) and Button-3 ? The following code works here just as expected:
from Tkinter import *
import ttk
root = Tk()
t = ttk.Treeview(root)
t.pack(fill='both', expand=1)
def test(event):
print 'hi'
t.bind('<3>', test)
root.mainloop()

I haven't used the treeview much yet, so maybe I am missing something,
but I do not see any way to do it. Maybe the problem is the way
ttk reports the widget width to the window manager, just a guess though.
For some reason you cannot configure the width of a treeview, maybe this
is related. I am not sure if this is intentional or a bug, but I am afraid
there is not much we can do here, the problem is apparently on the Tcl/Tk
side. Maybe you could file a bug report there?
Regards
Michael
