Re: how to style one particular treeview

The trick is to use the headings, not the tree itself :

set _names { ABC DEF GHI }

ttk::treeview .mytree -columns ignored -show headings -yscrollcommand { .scrY set }

.mytree heading ignored -text "Names"

foreach _item $_names {

  .mytree insert {} end -values $_item

}

ttk::scrollbar .scrY -command { .mytree yview }

pack .mytree -side left ; pack .scrY -side right -fill y

I am using one particular ttk::treeview as a listbox:
 
    ttk::frame .ignoresForm.ignoresListFrame
    set ignoresList [ttk::treeview \
        .ignoresForm.ignoresListFrame.ignoresList -striped true \
        -yscrollcommand {.ignoresForm.ignoresListFrame.scrolly set}]
    ttk::style configure List.Treeview -indent 0
    #ttk::style map List.Treeview -indent [list disabled 0 active 0]
    $ignoresList configure -show tree -selectmode browse \
        -style List.Treeview
    $ignoresList column #0 -anchor w -stretch true
    ttk::scrollbar .ignoresForm.ignoresListFrame.scrolly -orient vertical \
        -command {.ignoresForm.ignoresListFrame.ignoresList yview}
 
By default a ttk::treeview has an -indent of 20 pixels which makes sense
for trees but is not needed for lists.
 
In the code above I've tried to create a custom style to apply to one
treeview but it has no effect whether I use ttk::style configure or
ttk::style map.
 
What is the correct way to do this?
