Happens on
Python 2.7.2 (default, Jul 18 2011, 14:33:20)
[GCC 4.4.4 20100726 (Red Hat 4.4.4-13)] on linux2
TclVersion 8.5 TkVersion 8.5
with the program running on the above and the output being X'ed to an OSX
Mountain Lion iMac.
I just have to mouse over the ttk button and it changes (even if, for example,
Mail.app has the display focus). When I mouse over the buttons they get
slightly lighter color while the cursor is on them (the 'activebackground'
color?)
Same with
Python 2.7.2 (default, Jun 20 2012, 16:23:33)
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
>>> import Tkinter
>>> Tkinter.TclVersion
8.5
>>> Tkinter.TkVersion
8.5
on my iMac. Just running the mouse cursor over the button makes it change. No
activebackground color change on Mac.
