how to create a ttk::treeview without a border?

| How can I create a ttk::treeview widget without a border? The following
yields unsatisfactory results on windows but the following is my best
guess so far (emphasis on "guess"). I've tried several variations of
layouts but none seem to work. This, with tile 0.8 and tk 8.5b3.
package require Tk 8.5
proc main {} {
ttk::style layout FlatTree {
Treeview.padding -sticky nsew -border 0 -children {
Treeview.treearea -sticky nswe -border 0 -expand true
}
}
ttk::frame .f
pack .f -side top -fill both -expand true -padx 10 -pady 10
ttk::treeview .tree \
-style FlatTree \
-show tree
pack .tree -in .f -side top -fill both -expand true
set parent [.tree insert {} end -text Root -open true]
.tree insert $parent end -text One
.tree insert $parent end -text Two
.tree insert $parent end -text Three
}
main

What do you find unsatisfactory about it?
It looks to me like it does what you want (no border),
the only thing I see wrong is that the fill color behind
items doesn't match that of the blank region below.
Haven't tested on Windows, is it only a problem there?
I'd also suggest using "Flat.Treeview" as the style name
instead of "FlatTree"; the former will inherit all the
other Treeview settings (and there are plenty) defined
in the theme.

When there aren't enough items in the treeview to fill the widget, the
area below the last item takes a different background color.

Bingo. Oddly, with the border, the border fills the whole region and the
background looks fine. When I turn the border off, that's when I get the
blank region below which is highly undesireable.

I think so. Last I recall, it looked find on my mac when I was creating
it. A w or two passed, I tried running it on windows, and that's when
I noticed it didn't look right. I haven't tried it on *nix.

Thanks for the hint.
