Hi,

I am able to change the layout of ttk::treeview so that the indicator is not shown (I just leave out the Treeitem.indicator):

ttk::style layout Item {Treeitem.padding -sticky nswe -children {Treeitem.image -side left -sticky {} Treeitem.text -side left -sticky {}}}

At the same time, I use a custom style for one of the treeviews:

ttk::style configure navigation.Treeview -rowheight [expr {[font metrics TkTextFont -linespace] + 10}]

So, I can build a custom treeview with

ttk::treeview .t -show tree -style navigation.Treeview -padding 5
set itemID [.t insert {} end -text "an item"]
..t insert $itemID end -text "a subitem"

This, however will still show the indicator. How can I apply a style that will use *both* the custom rowheight *and* leave out the indicator? So to say a custom style that has both changes in one style name so the indicator removal doesn't apply to all treeviews.

Thanks, Torsten
