New submission from klappnase:
When trying to load third-party themes ttk.Style.theme_names() fails to list
available themes. For example if the themes from the tile-themes project are
installed one can do:
>>> from tkinter import *
>>> from tkinter import ttk
>>> root=Tk()
>>> s=ttk.Style()
>>> s.theme_names()
('clam', 'alt', 'default', 'classic')
>>> root.tk.call('ttk::themes')
('classic', 'default', 'clam', 'alt')
>>> root.tk.call('package', 'require', 'tile-themes')
'0.6'
>>> s.theme_names()
('clam', 'alt', 'default', 'classic')
>>> root.tk.call('ttk::themes')
('keramik', 'plastik', 'clam', 'winxpblue', 'alt', 'Aquativo', 'classic',
'default', 'keramik_alt')
>>>
This has been discussed in more detail at tkinter-discuss:
http://code.activestate.com/lists/python-tkinter-discuss/3373/
As ttk::themes is described as being part of the Public API inside ttk.tcl and
is also documented in the tcl wiki at http://wiki.tcl.tk/14796 resp.
http://wiki.tcl.tk/23676 it appears safe to add it to ttk.py.
Considering this I prepared a patch (against b10a9d4f08eb) that adds the
following method to ttk.Style():
def themes(self, pattern=None):
'''Returns a list of theme names available. It can be passed an
argument which is used as an lsearch glob pattern while looking
for the theme names.'''
return self.tk.splitlist(self.tk.call('ttk::themes', pattern))
