python怎么更改主题_如何更改tkinter应用程序的整体主题？

A number of operations related to themes require that you have

available an instance of the ttk.Style() class (in the Python sense of

class). For example, to obtain a list of the available themes in your

installation:

>>> import ttk # import tkinter.ttk as ttk for Python 3

>>> s=ttk.Style()

>>> s.theme_names()

('clam', 'alt', 'default', 'classic')

The .theme_names() method returns a tuple containing the names of the

available styles. The 'classic' theme gives you the original, pre-ttk

appearance.

To determine which theme you get by default, use the .theme_use()

method with no arguments. To change the current theme, call this same

method with the desired theme name as the argument:

>>> s.theme_use()

'default'

>>> s.theme_use('alt')

>>> s.theme_use()

'alt'
