Gtk::CellRendererCombo how to

[p_solntsev meta ua]

Hi,

Could you please provide a simple example how to use
Gtk::CellRendererCombo in Gtk::TreeView?

What I have for now is two column Gtk::TreeView. In first column (each
raw) I need ComboBox.

I have the following class for ComboModel. Is it necessary to have m_id
member?

class ModelColumnsRender : public Gtk::TreeModelColumnRecord
{
public:

  ModelColumnsRender()
    { add(m_name); }

  Gtk::TreeModelColumn<Glib::ustring> m_name;
}m_columnsrender;

Using m_columnsrender I can create a Gtk::ListTree model and populate it.

For TreeView itself, I also have the similar class as mentioned above:

class ModelColumns : public Gtk::TreeModelColumnRecord
{
public:

  ModelColumns()
    { add(m_name); add(m_amount) }

  Gtk::TreeModelColumn<Glib::ustring> m_name;
  Gtk::TreeModelColumn<Glib::ustring> m_amount;

}m_columns;

I can also create a ListStore model using m_columns.

Now I do the following:
// Create a column
auto render = Gtk::manage(new Gtk::CellRenderCombo);
auto pCol = Gtk::manage(new Gtk::TreeViewColumn("Animals"));

pCol->pack_start(*render, true);
treeview->append_column(*pCol);
treeview->append_column("Amount",m_columns.m_amount);

How can I add a model to my render? I tried

render->property_model() = refListStoreModelForCombo;

But no effect.

Where should I define the model for CellRenderCombo? inside of
ModelColumns class if so, how can I populate it?

Thanks.

-Pavlo
