Re: Gtk::CellRendererCombo how to

Thank you so much, Phil.

I didn't realized I have to insert ListStore model as value for each
row. Also, a little bit confusing was part render->property_editable()
= true. I see logic here now, but it wasn't clear. 

Surprisingly, I wasn't able to locate this example on the web site.

Thanks again.

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
raw) I need ComboBox.

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

class ModelColumnsRender : public Gtk::TreeModelColumnRecord

     { add(m_name); }

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

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

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

class ModelColumns : public Gtk::TreeModelColumnRecord

     { add(m_name); add(m_amount) }

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


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);

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?
