[New-bugs-announce] [issue37767] TTK Treeview alternating row color not working

[Christopher Caputo]

New submission from Christopher Caputo <mookiefer at 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.
