How do I make my ttk widgets look modern? - user-interface

Question

I am having a problem with tkinter.ttk on mac. I am using macports and python3.1. When I try to use tkinter.ttk I get very old looking gui elements.
eg: I get this
Instead of this:
The code I used is:
from tkinter import *
from tkinter import ttk
root = Tk()
button = ttk.Button(root, text="Hello World").grid()
root.mainloop()
I would be happy to provide any information from my computer needed to answer this question. As I am a novice programer please tell me where to find said information.
I have a Macbook 5,2 with Snow Leopard installed. Any help would be appreciated.
Thanks, Marlen
Question Update:
I installed tk #8.5.9_0+quartz as schlenk suggested only to get this error:
TclMacOSXNotifierAddRunLoopMode: Tcl not built with CoreFoundation support Abort trap
I fixed this error with the patch from https://trac.macports.org/ticket/22954. I followed the instructions to the letter(they are):
$ cd /opt/local/var/macports/sources/rsync.macports.org/release/ports/lang/tcl
$ sudo patch < ~/Downloads/tcl.2.patch
$ sudo port install tcl
This created a new error which is:
Traceback (most recent call last):

This probably means that tk wasn't installed properly.

Answer 1

The problem might be macports. There are three versions of Tk you could use as the basis for your ttk. The screenshot looks a lot like the older X11 Tk, not the aqua based Tk.
1. Tk via X11.
2. Tk compiled with Carbon 'windowingsystem -aqua'
3. Tk compiled with Cocoa
So you should try to either build a Tk variant 'quartz' via macports or you should get some prebuilt version (e.g. ActiveStates) that has the right version already built.
So try:
sudo port build tk #8.5.9+quartz
Have a look at tutorials here for some more guidance:

Answer 2

try
style = ttk.Style()
print(style.theme_names())
style.theme_use('default') # change 'default' to something better

Answer 3

I haven't played with ttk, however I have a decent amount of experience with tkinter. I belive you have to fill out the style keyword argument.
I think it would look something like this.
from tkinter import *
from tkinter import ttk
root = Tk()
button = ttk.Button(root, text="Hello World", style="somestyle").grid()
root.mainloop()
