One of the widgets it includes is a tree widget, which can be configured to display multiple columns of informational data without displaying the tree itself. This is a simple way to build a listbox that has multiple columns. Clicking on the heading for a column will sort the data by that column. You can also change the width of the columns by dragging the boundary between them."

## Code to insert the data nicely
set font [ttk::style lookup [$w.tree cget -style] -font]

}
}
}
## Code to do the sorting of the tree contents when clicked on
proc SortBy {tree col direction} {
# Build something we can sort
set data {}
foreach row [$tree children {}] {
lappend data [list [$tree set $row $col] $row]
}
set dir [expr {$direction ? "-decreasing" : "-increasing"}]
set r -1
# Now reshuffle the rows into the sorted order
foreach info [lsort -dictionary -index 0 $dir $data] {
$tree move [lindex $info 1] {} [incr r]
}
# Switch the heading so that it will sort in the opposite direction
$tree heading $col -command [list SortBy $tree $col [expr {!$direction}]]
}
