**Introduction**

This page is intended to collect in one place various bits of knowledge gained through much trial, many errors, and some reading the [C] code of the [Tile] widget set.  The intent is to not have to repeat the trial, error, or reading in order to remember how to utilize the [ttk::style] command to style various [Ttk] [widget]s.  This initial version is quite incomplete, as it only documents those bits I've deduced so far.  This is for Tk 8.5.8.

[dzach] (2015-9-23) I changed the style to be similar to the [tklib], added a few more ''ttk::style'' configuration options for ''Treeview'' and ''Treeview.Heading'' styles, which I have confirmed working with wish8.6. The mappings for ''Treeview.Heading'' are also confirmed to work. However, I have not been able to configure the style of some of the rest of the elements that appear on this page, namely ''Treeview.Row, Treeview.Item, Treeview.Cell'' and I have marked them with a (?). Maybe someone else can confirm those too, hopefully with an example on this page, and delete this part of the note.

'''ttk::style configure Treeview.Row''' ''?options?''

   -'''background''' ''color'':     Configures the background color of rows that contain data values when applied to a .Row style sub-selector. (?)

   -'''padding''' ''[list pixels ...]'':   Additional padding to include inside the border of the cells (columns #1, #2, ...), but not of the tree items
   -''...'':    

'''ttk::style map Treeview.Heading''' ''?options?''

   -'''background''' ''[list active color !active color ...]'':   Configures the background color of the heading for various states
   -''...'':    

'''ttk::style map Treeview.Row''' ''?options?''

'''ttk::style map Treeview.Cell''' ''?options?''

'''ttk::style map Treeview.Item''' ''?options?''

'''ttk::style configure Horizontal.Sash''' ''?options?''

   -'''sashthickness pixels''':   Configures the thickness of the sash between the panes of the paned window. Thickness is in pixels. Note that the vertical sash is used for the '-orient horizontal' layout of the panedwindow and vice versa. Also note that the sash seems not accessible anymore if the thickness is set to 1 (this is with Tk 8.6b3 on a Mac). It would also be great, if the color of the sash could be altered, but see also the section on "Create a custom sash handle bar" on this page: [ttk::panedwindow].
