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.
-fieldbackground Configures the background color of the unused portion of a treeview widget (any area not covered by rows of data). Example: ttk::style configure Treeview -fieldbackground color -background Configures the background color of rows that contain data values when applied to a .Row style sub-selector. Example: ttk::style configure Treeview.Row -background color -foreground Configures the foreground color used to draw items in the tree column (#0) when applied to an .Item style sub-selector. Configures the foreground color used to draw items in the tree column (#0) when applied to an .Item style sub-selector. Configures the foreground color used to draw non-tree (-values list) columns when applied to a .Cell style sub-selector. Examples: ttk::style configure Treeview.Item -foreground color ttk::style configure Treeview.Cell -foreground color -rowheight Adjusts the rowheight (spacing between rows) in the treeview, distance is in pixels. Example: ttk::style configure Treeview -rowheight height -indent Adjusts the indentation amount of child elements below parent elements within the tree column. 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 ttk::style map Treeview.Cell -background list selected color 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
