Iterating over Model Rows

Gtk::TreeModel provides a C++ Standard Library-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 container of child Rows:

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