Moving rows included on a gtk treeview using a single button

Hello everybody i’m new here :), I’m trying to get handle of gtk
treeviews,
right now, i know how to create rows, columns and some else, but i have
a
problem, i want to move the rows using a button, come on the classic up
and
down, well i don’t an idea to do that =/ i’m learning about ruby + gtk,
i
think this combination is simply wow, here is the code i’m using glade,
libglade can someone let me a little of light?, some example to do that
or
just talk me something about, using glade or simple gtk.

Try putting something like this in Treeview.initialize:

down_button = @glade["button4"]
down_button.signal_connect("clicked"){
  selected_item = @treeview.selection.selected
  @model.move_before( selected_item, nil )  # move to end of list
}

This will cause the block of code, between { and }, to be executed
when the down button is clicked. This code will move the
selected row to the bottom of the list. This isn’t exactly what
you want. You’ll have to read the documentation for Gtk::TreeStore
to find out how to do it. Also this code does not do any error
checking, it crashes if no line is selected when you press the down
button. Something else that can be easily fixed.

I hope this helps. And welcome to ruby/gtk!
