Hello,

I was searching the list archives for an answer to the same question,
but I only found the question itself, unanswered; so, I'm reiterating
the question :)

I created a model:

Glib::RefPtr<Gtk::ListStore> editorListModel;
class EditorListModelColumns : public Gtk::TreeModel::ColumnRecord
{
public:
	EditorListModelColumns() { add(name); add(command); }

	Gtk::TreeModelColumn<Glib::ustring> name;
	Gtk::TreeModelColumn<Glib::ustring> command;
};
EditorListModelColumns editorListModelColumns;

Then I tried to use it in a ComboBox:

    editorListModel = Gtk::ListStore::create(editorListModelColumns);
    Gtk::TreeModel::Row row = *(editorListModel->append());
    row[editorListModelColumns.name] = "mutt";
    row[editorListModelColumns.command] = "mutt -f %p";
    row = *(editorListModel->append());
    row[editorListModelColumns.name] = "other";
    row[editorListModelColumns.command] = "sampleeditor --folder %p";

    line = Gtk::manage(new Gtk::HBox());
    diavbox->pack_start(*line, false, false);
    line->pack_start(*manage(new Gtk::Label("Mail editor:")), true, true);
    Gtk::ComboBox* cb;
    line->pack_start(*manage(cb = new Gtk::ComboBox()), false, false); 
    cb->pack_start(editorListModelColumns.name);

But the combo box shows up empty.

What am I doing wrong?


Ciao,

Enrico
