**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:: widgets.

**[ttk::treeview%|%treeview%|%]**

   -fieldbackground:   Configures the background color of the unused portion of a treeview widget (any area not covered by rows of data).<<br>><<br>>Example: ttk::style configure Treeview -fieldbackground color<<br>><<br>>

   -background:   Configures the background color of rows that contain data values when applied to a .Row style sub-selector.<<br>><<br>>Example: ttk::style configure Treeview.Row -background color<<br>><<br>>

   -foreground:   Configures  the  foreground color used to draw items in the tree column (#0) when applied to an .Item style sub-selector.<<br>><<br>>Configures the foreground color used to draw items in the tree column (#0) when applied to an .Item style sub-selector.<<br>><<br>>Configures the foreground color used to draw non-tree (-values list) columns when applied to a .Cell style sub-selector.<<br>><<br>>Examples:<<br>>ttk::style configure Treeview.Item -foreground color<<br>>ttk::style configure Treeview.Cell -foreground color<<br>><<br>>

   -rowheight:   Adjusts  the  rowheight  (spacing between rows) in the treeview, distance is in pixels.<<br>><<br>>Example: ttk::style configure Treeview -rowheight height<<br>><<br>>

   -indent:   Adjusts the indentation amount of child elements below parent elements within the tree column.<<br>><<br>>Example: ttk::style configure Treeview -indent distance

Adjustment  of  the  background color of selected items in the treeview uses the ttk::style map sub-command applied to the style  sub-selectors above:

ttk::style map Treeview.Row  -background [ list selected color ]<<br>>
ttk::style map Treeview.Cell -background [ list selected color ]<<br>>
ttk::style map Treeview.Item -background [ list selected color ]

Adjustment of the background color of the the column heading labels uses  the ttk::style map sub-commend applied to the .Heading style sub-selector:

ttk::style map Treeview.Heading -background [ list active  color !active color ]
