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.

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.
