Python - Gtk.TreeView with CheckBox

Question

I need to store items in a Gtk TreeView and when interacting with this TreeView, the user will can select one or more items in the list.

Because I'm new to GTK, I managed to populate the treeview and display a checkbox as the code below shows. But when I try to select, nothing happens and I do not know how to make this possible.

This is my Code:

# the column is created
renderer_products = gtk.CellRendererText()
column_products = gtk.TreeViewColumn("Products", renderer_products, text=0)
# and it is appended to the treeview
view.append_column(column_products)

# the column checkbox is created
renderer_checkbox = gtk.CellRendererToggle()
column_checkbox = gtk.TreeViewColumn("Selected", renderer_checkbox, text=0)
# and it is appended to the treeview
view.append_column(column_checkbox)

If you want to select the whole row and something happen:

#double click or not double click use
Gtk.TreeView.set_activate_on_single_click (bool)
#connect the treeview
treeview.connect ("row-activated", on_row_activate)
#inside the callback
def on_row_activate (treeview, path, column):
    model = treeview.get_model ()
    iter  = treeview.get_iter (path)
    yourdata = model[iter][model_index]
    #do whatever with yourdata

If you want when you click the toggle and something happen:

#connect the renderer
renderer_checkbox.connect ("toggled", on_selected_toggled)
#inside the callback
def on_selected_toggled (renderer, path):
    #modify the model or get the value or whatever

Thanks, luciomrx. But your second tip does not solve. The signal "toggled" not exists in GetTreeViewColumn. — Eduardo, Jul 28 '14 at 13:41
