tkinter ttk themed widgets
The tkinter.ttk module provides access to the Tk themed widget set, introduced in Tk 8.5. Using the Ttk widgets gives the application an improved look and feel.
1) Platform-specific appearance
Your application can look like a Windows application under Windows, like a Linux app under Linux, and so on, without any change to your program.
2) Simplication of the widgets behaviour
The ttk module collapses a lot of the special cases into a simple system.
3) 6 new widgets
Combobox, Notebook, Progressbar, Separator, Sizegrip and Treeview.
from tkinter import ttk
