## Iterating over Model Rows

Gtk::TreeModel provides an STL-style container of its children, via the children() method. You can use the familiar begin() and end() methods iterator incrementing, like so:

    typedef Gtk::TreeModel::Children type_children; //minimise code length.
    type_children children = refModel->children();
    for(type_children::iterator iter = children.begin(); iter != children.end(); ++iter)
    {
      Gtk::TreeModel::Row row = *iter;
      //Do something with the row - see above for set/get.
    }

### Row children

When using a Gtk::TreeStore, the rows can have child rows, which can have their own children in turn. Use Gtk::TreeModel::Row::children() to get the STL-style container of child Rows:

    Gtk::TreeModel::Children children = row.children();
