Ooh!  Ooh!  I know!

Treeviews now respond to onChange when the user clicks on an item.  Somehow
I'd overlooked this when I originally coded that nasty onEvent method.  If
you change onEvent_TV() in the demo to the code below, it will work fine (or
at least work as it was designed to :).

-- Start code
procedure TV_onChange( )
    atom ix
    if deleteItem( LV, -1 ) then end if
    lParams -= lParams
    current = getIndex( TV )

    -- show items

    ix = 1

    while ix <= length( location ) do
        if location[ix] = current then
            lParams[ix] = addLVItem( LV, lv[ix][3], lv[ix][1..2] )
        end if
        ix += 1
    end while
end procedure
onChange[TV] = routine_id( "TV_onChange" )
-- End Code
