New submission from Christopher Caputo <mookie...@gmail.com>:
The default installation of Python3.7 on all my Win10 machines has a ttk theme
file that disables treeview alternating row colors. The specific file for me is
"vistaTheme.tcl" located at "C:\Program Files\Python37\tcl\tk8.6\ttk". In the
#Treeview section of the file the "ttk::style map Treeview" line needed to be
changed from:
ttk::style map Treeview \
-background [list disabled $colors(-frame)\
{!disabled !selected} $colors(-window) \
selected SystemHighlight] \
-foreground [list disabled $colors(-disabledfg) \
{!disabled !selected} black \
selected SystemHighlightText]
Changed to:
ttk::style map Treeview
-background [list selected SystemHighlight]
-foreground [list selected SystemHighlightText]
Essentially all the "disabled" parts needed to be removed.
