there seems to be no "post()" method or something like that for the
ttk.Combobox, but what you want can be done with a little trickery:
from Tkinter import *
import ttk
class ComboBox(ttk.Combobox):
def __init__(self, *args, **kw):
ttk.Combobox.__init__(self, *args, **kw)
def post(self, event=None):
self.update_idletasks()
x, y = self.winfo_x(), self.winfo_y()
self.event_generate('<1>', x=x+self.winfo_width()-3, y=y+3)
root = Tk()
c = ComboBox(root, values=('foo', 'bar', 'baz'))
c.set('foo')
c.pack(padx=50, pady=50)
e = Entry(root)
e.pack(pady=(0,50))
e.focus()
root.bind('<F1>', c.post)
root.mainloop()
I hope this helps
Michael
