## Constructor & Destructor Documentation

Gtk::TreeStore::TreeStore | ( | TreeStore&& | src | ) |
| noexcept

Gtk::TreeStore::~TreeStore | ( |  | ) |
| overridenoexcept

Gtk::TreeStore::TreeStore | ( |  | ) |
| protected

When using this constructor, you must use set_column_types() immediately afterwards.

This can be useful when deriving from this class, with a fixed TreeModelColumnRecord that is a member of the class. There is no create() method that corresponds to this constructor, because this constructor should only be used by derived classes.

Gtk::TreeStore::TreeStore | ( | const TreeModelColumnRecord& | columns | ) |
| explicitprotected

## Member Function Documentation

iterator Gtk::TreeStore::append | ( |  | ) |

Creates a new row at the end of the top-level.

The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and prepend().

Returns
  An iterator to the new row.

iterator Gtk::TreeStore::append | ( | const TreeNodeChildren& | node | ) |

Creates a new row at the end of the row's children.

The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and prepend().

Parameters

  node | The list of the parent row's children, as returned by Gtk::TreeModel::iterator::children().

Returns
  An iterator to the new row.

void Gtk::TreeStore::clear | ( |  | ) |

Removes all rows from tree_store.

static Glib::RefPtr<TreeStore> Gtk::TreeStore::create | ( | const TreeModelColumnRecord& | columns | ) |
| static

Instantiate a new TreeStore.

Parameters

  columns | The column types for this tree model.

Returns
  The new TreeStore.

iterator Gtk::TreeStore::erase | ( | const iterator& | iter | ) |

Removes the given row from the list store.

Parameters

  iter | The iterator to the row to be removed.

Returns
  An iterator to the next row, or end() if there is none.

static GType Gtk::TreeStore::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

GtkTreeStore* Gtk::TreeStore::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GtkTreeStore* Gtk::TreeStore::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

GtkTreeStore* Gtk::TreeStore::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

iterator Gtk::TreeStore::insert | ( | const iterator& | iter | ) |

Creates a new row before the position.

If iter is end() then a new row will be appended to the list. The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also prepend() and append().

Parameters

  iter | An iterator to the row before which the new row will be inserted.

Returns
  An iterator to the new row.

iterator Gtk::TreeStore::insert_after | ( | const iterator& | iter | ) |

Creates a new row after the position.

If iter is end() then a new row will be prepended to the list. The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also prepend() and append().

Parameters

  iter | An iterator to the row after which the new row will be inserted.

Returns
  An iterator to the new row.

bool Gtk::TreeStore::is_ancestor | ( | const iterator& | iter,
|  | const iterator& | descendant
| ) |  | const

Returns `true` if iter is an ancestor of descendant.

That is, iter is the parent (or grandparent or great-grandparent) of descendant.

Parameters

  iter | A valid Gtk::TreeIter.
  descendant | A valid Gtk::TreeIter.

Returns
  `true`, if iter is an ancestor of descendant.

int Gtk::TreeStore::iter_depth | ( | const iterator& | iter | ) | const

Returns the depth of iter.

This will be 0 for anything on the root level, 1 for anything down a level, etc.

Parameters

  iter | A valid Gtk::TreeIter.

Returns
  The depth of iter.

bool Gtk::TreeStore::iter_is_valid | ( | const iterator& | iter | ) | const
| virtual

WARNING: This function is slow.

Only use it for debugging and/or testing purposes.

Checks if the given iter is a valid iter for this Gtk::TreeStore.

Since gtkmm 2.2:

Parameters

  iter | A Gtk::TreeIter.

Returns
  `true` if the iter is valid, `false` if the iter is invalid.

Reimplemented from Gtk::TreeModel.

void Gtk::TreeStore::iter_swap | ( | const iterator& | a,
|  | const iterator& | b
| ) |  |

Swaps a and b in the same level of tree_store.

Note that this function only works with unsorted stores.

Since gtkmm 2.2:

Parameters

  a | A Gtk::TreeIter.
  b | Another Gtk::TreeIter.

void Gtk::TreeStore::move | ( | const iterator& | source,
|  | const iterator& | destination
| ) |  |

Moves source to the position at destination.

source and destination should be at the same level. Note that this function only works with unsorted stores.

Parameters

  source | The row that should be moved.
  destination | The position to move to.

TreeStore& Gtk::TreeStore::operator= | ( | TreeStore&& | src | ) |
| noexcept

iterator Gtk::TreeStore::prepend | ( |  | ) |

Creates a new row at the start of the top-level.

The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and append().

Returns
  An iterator to the new row.

iterator Gtk::TreeStore::prepend | ( | const TreeNodeChildren& | node | ) |

Creates a new row at the start of the row's children.

The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and append().

Parameters

  node | The list of the parent row's children, as returned by Gtk::TreeModel::iterator::children().

Returns
  An iterator to the new row.

void Gtk::TreeStore::reorder | ( | const TreeNodeChildren& | node,
|  | const Glib::ArrayHandle< int > & | new_order
| ) |  |

Reorders the children of node to follow the order indicated by new_order.

Note that this function only works with unsorted stores.

void Gtk::TreeStore::set_column_types | ( | const TreeModelColumnRecord& | columns | ) |

virtual void Gtk::TreeStore::set_value_impl | ( | const iterator& | row,
|  | int | column,
|  | const Glib::ValueBase & | value
| ) |  |
| protectedvirtual

Override and implement this in a derived TreeModel class, so that Row::operator() and Row::set_value() work.

You can probably just implement this by calling set_value_vfunc(). Your implementation of set_value_impl() should also call row_changed() after changing the value.

Reimplemented from Gtk::TreeModel.
