## Detailed Description

Base of TreeIter.

Contains the common parts of TreeIter<TreeRow> and TreeIter<TreeConstRow>.

## Member Function Documentation

## ◆ equal()

bool Gtk::TreeIterBase3::equal | ( | const TreeIterBase3& | other | ) | const

## ◆ get_stamp()

int Gtk::TreeIterBase3::get_stamp | ( |  | ) | const

This is only useful when implementing a custom Gtk::TreeModel class.

Compare the iterator's stamp with your model's stamp to discover whether it is valid.

See also
  set_stamp().

Returns
  The iterator's stamp.

## ◆ set_stamp()

void Gtk::TreeIterBase3::set_stamp | ( | int | stamp | ) |

This is only useful when implementing a custom Gtk::TreeModel class.

Set the stamp to be equal to your model's stamp, to mark the iterator as valid. When your model's structure changes, you should increment your model's stamp to mark all older iterators as invalid. They will be recognised as invalid because they will then have an incorrect stamp.
