Hi Sorin, thanks for giving ttk a try.

I will answer in the reverse order.

The easier way to know what defines the actual TkDefaultFont is to use
the tkFont module (it is included with tkinter):

import Tkinter
import tkFont
Tkinter.Tk()
print tkFont.Font(font='TkDefaultFont').configure()

Now, to change the selection colors in a ttk.Entry, simply do:

import ttk
style = ttk.Style()
style.map('TEntry', selectbackground=[('!disabled', 'white')],
selectforeground=[('!disabled', 'grey')])

And to change the ttk.Entry font to italics you don't use themes
actually. There is an option named 'font' for this widget, so you just
have to change it. Follows the correct way to do what you are after:

import ttk
import tkFont

entry = ttk.Entry()
myfont = tkFont.Font(font=str(entry['font']))
myfont['slant'] = 'italic'
entry['font'] = myfont
entry.pack()
