Tkinter look (theme) in Linux

Question

I know that Tkinter is not so modern, not so cool and maybe better to use PyQt or etc.

But it is interesting for me can Tkinter look not so ugly in Ubuntu (Linux). Looks that brew version (in OS X) of python's Tkinter compiled with built-in theme and looks good:

But Ubuntu's Tkinter makes me cry:

I've read that for good theme I need to use ttk, but I dont know exactly how. My code looks as follow:

from Tkinter import *

class App():
  def __init__(self, master):
    frame = Frame(master)
    frame.pack()

    master.title("Just my example")
    self.label = Label(frame, text="Type very long text:")

    self.entry = Entry(frame)

    self.button = Button(frame,
                         text="Quit", fg="red", width=20,
                         command=frame.quit)


    self.slogan = Button(frame,
                         text="Hello", width=20,
                         command=self.write_slogan)

    self.label.grid(row=0, column=0)
    self.entry.grid(row=0, column=1)
    self.slogan.grid(row=1, column=0)
    self.button.grid(row=1, column=1)

  def write_slogan(self):
    print "Tkinter is easy to use!"

root = Tk()
app = App(root)
root.mainloop()

How to apply standard ubuntu theme or at least better theme?

Thanks.

All available themes of ttk can be seen with such commands:

$ python
>>> import ttk
>>> s=ttk.Style()
>>> s.theme_names()
('clam', 'alt', 'default', 'classic')

So you can use 'clam', 'alt', 'default', 'classic' themes with your version of Tkinter.

After trying all of them I think the best one is 'clam'. You can use this one or any other in following way:

from Tkinter import *
from ttk import *

class App():
  def __init__(self, master):
    frame = Frame(master)
    frame.pack()

    master.title("Just my example")
    self.label = Label(frame, text="Type very long text:")

    self.entry = Entry(frame)

    self.button = Button(frame,
                         text="Quit", width=15,
                         command=frame.quit)


    self.slogan = Button(frame,
                         text="Hello", width=15,
                         command=self.write_slogan)

    self.label.grid(row=0, column=0)
    self.entry.grid(row=0, column=1)
    self.slogan.grid(row=1, column=0, sticky='e')
    self.button.grid(row=1, column=1, sticky='e')

  def write_slogan(self):
    print "Tkinter is easy to use!"

root = Tk()
root.style = Style()
#('clam', 'alt', 'default', 'classic')
root.style.theme_use("clam")

app = App(root)
root.mainloop()

Result:

OS X uses precompiled theme "aqua" so widgets are looking better.

Also Ttk widgets do not support all option which pure Tkinter does.
