Tk 8.5 you may still use this module as long as you have Tile installed, but

rendering under X11, window transparency (on X11 you will need a composition

+Writing new tests
+=================
+
+Precaution
+----------
+
+ New tests should always use only one Tk window at once, like all the
+ current tests do. This means that you have to destroy the current window
+ before creating another one, and clean up after the test. The motivation
+ behind this is that some tests may depend on having its window focused
+ while it is running to work properly, and it may be hard to force focus
+ on your window across platforms (right now only test_traversal at
+ test_ttk.test_widgets.NotebookTest depends on this).

+This module provides classes to allow using Tk themed widget set.

+Ttk is based on a revised and enhanced version of

+
+Its basic idea is to separate, to the extent possible, the code
+implementing a widget's behavior from the code implementing its
+appearance. Widget class bindings are primarily responsible for
+maintaining the widget state and invoking callbacks, all aspects
+of the widgets appearance lies at Themes.

+- Added the ttk module. See issue #2983: Ttk support for Tkinter.
+
- Removed isSequenceType(), isMappingType, and isNumberType() from the
operator module; use the abstract base classes instead. Also removed
the repeat() function; use mul() instead.
