(1) The signature of the function "add_attribute()" in:
pColumn->add_attribute(pActive->property_active (), m_columns.active); does not match with those in the api. API Reference: http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1TreeViewColumn.html "pActive->property_active ()" should return either "true" or "false" (2) I have placed Gtk::CellRendererToggle and Gtk::CellRendererText in the same Gtk::TreeViewColumn The toggle renderer can be checked or unchecked. Here are some codes that I used: renderer_toggle.property_activatable() = true; treeview_col.set_title("Selected"); treeview_col.pack_start(renderer_toggle, true); treeview_col.add_attribute(renderer_toggle, "active", 0); (3) By the way, I try to use `property_editable' but the compiler complains with: `class Gtk::CellRendererToggle' has no member named `property_editable' Please make sure you are using the most recent version of Gtkmm.
