I don't understand, Tk treats literal TAB escape sequence inside strings, passed in an AbstractString[] to TreeView, but only when not surrounded by spaces on either side. I red in the documentation that this widget can also be used to make grids/tables, but there is no example. Is it trying to make a grid with the tab separated values? It's always the second word of tab separated words, from the last string in the array, the one that appears to be passed to tcl_eval (can't understand how) as an argument:

My case was even more weird since it worked at first. I was just testing Tk and ODBC (total GUI noob here). I put it here in case it's useful.

I have an app like this:

#!/usr/bin/env julia


using ODBC, Tk, DataFrames


function update_app(w)
    info("Actualizando!")
    datos = query("SELECT * FROM alertas;")
    registros = AbstractString[]
    for dato in eachrow(datos)
        id             = dato[:id]
        ip             = dato[:ip]
        lugar          = dato[:lugar]
        fecha          = dato[:fecha_hora]
        latitud        = dato[:latitud]
        longitud       = dato[:longitud]
        atendido       = dato[:atendido]
        fecha_atendido = dato[:fecha_hora_atendido]
        registro = [id, ip, lugar, fecha, latitud, longitud, atendido, fecha_atendido]
        registro = join(registro, "\t")   # Booom!!!
        push!(registros, registro)
    end

    pop!(w.children)
    f = Frame(w)
    pack(f, expand = true, fill = "both")
    f1 = Frame(f)    # need internal frame for use with scrollbars
    lb = Treeview(f1, reverse(registros))
    scrollbars_add(f1, lb)
    pack(f1, expand = true, fill = "both")
    b = Button(f, "Ok")
    pack(b)
    bind(b, "command") do path
        ip_addr = match(r"^.*?(\d+\.\d+\.\d+\.\d+)\s*.*$", get_value(lb)[1]).captures[1]
        run(`firefox "http://$(ip_addr):9000"`)
    end
    sleep(5)
    forget(f)
    update_app(w)
end

function c5_app()
    w = Toplevel("Consola C5")
    set_size(w, 500, 300)
    tcl("pack", "propagate", w, false)
    Frame(w)
    update_app(w)
end

ODBC.connect("c5db")
c5_app()

And the table looks like this:

It works!

screenshot_20160421_014031

But oddly if add a new register to the database, it breaks, and only the last entry is an error now!

MariaDB [c5db]> insert into alertas (id, ip, lugar, fecha_hora, latitud, longitud, atendido, fecha_hora_atendido)
 values (19, "Booom!!!", "test", NOW(), 13.1416, 13.1416, 0, now());
Query OK, 1 row affected (0.02 sec)

Now it's broken:

So I finally understood that changing \t for spaces solves the issue, but why? And why only when I inserted a new record with sql? (I'll have to look the exact SQL code used by my friend who populated the database and adds records via clicks on a RaspberryPi button, still I really can't see why this matters), if I add more registers to the table, it only fails from now on with the last register, second word between tabs, ie: ["OK\tOK\tOK", "OK\tOK\tOK", "OK\tBooom!!!\tOK?"]
here ---------------------------------------------------------^

I seem to be good as long as I change the tabs for spaces, ie: registro = join(registro, "\t") for registro = join(registro, " ").
