## Detailed Description

A widget used to choose from a list of items.

A ComboBox is a widget that allows the user to choose from a list of valid choices. The ComboBox displays the selected choice. When activated, the ComboBox displays a popup which allows the user to make a new choice. The style in which the selected value is displayed, and the style of the popup is determined by the current theme. It may be similar to a Windows-style combo box.

The ComboBox uses the model-view pattern; the list of valid choices is specified in the form of a tree model, and the display of the choices can be adapted to the data in the model by using cell renderers, as you would in a tree view. This is possible since ComboBox implements the CellLayout interface. The tree model holding the valid choices is not restricted to a flat list, it can be a real tree, and the popup will reflect the tree structure.

To allow the user to enter values not in the model, the 'has-entry' property allows the ComboBox to contain a Gtk::Entry. This entry can be accessed by calling get_entry(), or you can just call get_entry_text() to get the text from the Entry.

For a simple list of textual choices, the model-view API of ComboBox can be a bit overwhelming. In this case, ComboBoxText offers a simple alternative. Both ComboBox and ComboBoxText can contain an entry.

The ComboBox widget looks like this:

## Constructor & Destructor Documentation

virtual Gtk::ComboBox::~ComboBox | ( |  | ) |

virtual

Gtk::ComboBox::ComboBox | ( | bool | has_entry = `false` | ) |

explicit

Creates a new empty ComboBox, optionally with an entry.

Parameters

  has_entry | If this is true then this will have an Entry widget.

Gtk::ComboBox::ComboBox | ( | const Glib::RefPtr< TreeModel >& | model,
|  | bool | has_entry = `false`
| ) |  |

explicit

Creates a new ComboBox with the model initialized to model, optionally with an entry.

Parameters

  model | The model containing data to display in the ComboBox.
  has_entry | If this is true then this will have an Entry widget.

Gtk::ComboBox::ComboBox | ( | const Glib::RefPtr< CellArea >& | cell_area,
|  | bool | has_entry = `false`
| ) |  |

explicit

Creates a new empty ComboBox using cell_area to layout cells, optionally with an entry.

Parameters

  cell_area | The CellArea to use to layout cell renderers.
  has_entry | If this is true then this will have an Entry widget.

## Member Function Documentation

TreeModel::iterator Gtk::ComboBox::get_active | ( |  | ) |

Gets an iterator that points to the current active item, if it exists.

Returns
  The iterator.

TreeModel::const_iterator Gtk::ComboBox::get_active | ( |  | ) | const

Gets an iterator that points to the current active item, if it exists.

Returns
  The iterator.

Glib::ustring Gtk::ComboBox::get_active_id | ( |  | ) | const

Returns the ID of the active row of combo_box.

This value is taken from the active row and the column specified by the Gtk::ComboBox::property_id_column() property of combo_box (see set_id_column()).

The returned value is an interned string which means that you can compare the pointer by value to other interned strings and that you must not free it.

If the Gtk::ComboBox::property_id_column() property of combo_box is not set, or if no row is active, or if the active row has a `0` ID value, then `0` is returned.

Since gtkmm 3.0:

Returns
  The ID of the active row, or `0`.

void Gtk::ComboBox::get_active_id | ( | const Glib::ustring & | active_id | ) |

Changes the active row of combo_box to the one that has an ID equal to active_id, or unsets the active row if active_id is `0`.

Rows having a `0` ID string cannot be made active by this function.

If the Gtk::ComboBox::property_id_column() property of combo_box is unset or if no row has the given ID then the function does nothing and returns `false`.

Since gtkmm 3.0:

Deprecated:
  Use set_active_id(). This method was incorrectly named.

Parameters

  active_id | The ID of the row to select, or `0`.

Returns
  `true` if a row with a matching ID was found. If a `0` active_id was given to unset the active row, the function always returns `true`.

int Gtk::ComboBox::get_active_row_number | ( |  | ) | const

Returns the index of the currently active item, or -1 if there's no active item.

If the model is a non-flat treemodel, and the active item is not an immediate child of the root of the tree, this function returns `gtk_tree_path_get_indices (path)[0]`, where `path` is the Gtk::TreePath of the active item.

Since gtkmm 2.4:

Returns
  An integer which is the index of the currently active item, or -1 if there's no active item.

bool Gtk::ComboBox::get_add_tearoffs | ( |  | ) | const

Gets the current value of the :add-tearoffs property.

Returns
  The current value of the :add-tearoffs property.

SensitivityType Gtk::ComboBox::get_button_sensitivity | ( |  | ) | const

Returns whether the combo box sets the dropdown button sensitive or not when there are no items in the model.

Since gtkmm 2.14:

Returns
  Gtk::SENSITIVITY_ON if the dropdown button is sensitive when the model is empty, Gtk::SENSITIVITY_OFF if the button is always insensitive or Gtk::SENSITIVITY_AUTO if it is only sensitive as long as the model has one item to be selected.

int Gtk::ComboBox::get_column_span_column | ( |  | ) | const

Returns the column with column span information for combo_box.

Since gtkmm 2.6:

Returns
  The column span column.

Entry* Gtk::ComboBox::get_entry | ( |  | ) |

See Also
  Bin::get_child().

Since gtkmm 2.24:

const Entry* Gtk::ComboBox::get_entry | ( |  | ) | const

See Also
  Bin::get_child().

Since gtkmm 2.24:

Glib::ustring Gtk::ComboBox::get_entry_text | ( |  | ) | const

Get the text in the entry, if there is an entry.

Since gtkmm 2.24:

int Gtk::ComboBox::get_entry_text_column | ( |  | ) | const

Returns the column which combo_box is using to get the strings from to display in the internal entry.

Since gtkmm 2.24:

Returns
  A column in the data source model of combo_box.

bool Gtk::ComboBox::get_focus_on_click | ( |  | ) | const

Returns whether the combo box grabs focus when it is clicked with the mouse.

See set_focus_on_click().

Since gtkmm 2.6:

Returns
  `true` if the combo box grabs focus when it is clicked with the mouse.

bool Gtk::ComboBox::get_has_entry | ( |  | ) | const

Returns whether the combo box has an entry.

Since gtkmm 2.24:

Returns
  Whether there is an entry in combo_box.

int Gtk::ComboBox::get_id_column | ( |  | ) | const

Returns the column which combo_box is using to get string IDs for values from.

Since gtkmm 3.0:

Returns
  A column in the data source model of combo_box.

Glib::RefPtr<TreeModel> Gtk::ComboBox::get_model | ( |  | ) |

Returns the Gtk::TreeModel which is acting as data source for combo_box.

Since gtkmm 2.4:

Returns
  A Gtk::TreeModel which was passed during construction.

Glib::RefPtr<const TreeModel> Gtk::ComboBox::get_model | ( |  | ) | const

Returns the Gtk::TreeModel which is acting as data source for combo_box.

Since gtkmm 2.4:

Returns
  A Gtk::TreeModel which was passed during construction.

Glib::RefPtr<Atk::Object> Gtk::ComboBox::get_popup_accessible | ( |  | ) |

Gets the accessible object corresponding to the combo box's popup.

This function is mostly intended for use by accessibility technologies; applications should have little use for it.

Since gtkmm 2.6:

Returns
  The accessible object corresponding to the combo box's popup.

Glib::RefPtr<const Atk::Object> Gtk::ComboBox::get_popup_accessible | ( |  | ) | const

Gets the accessible object corresponding to the combo box's popup.

This function is mostly intended for use by accessibility technologies; applications should have little use for it.

Since gtkmm 2.6:
