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.
}
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();
