## Detailed Description

Renders a combobox in a cell.

CellRendererCombo renders text in a cell like CellRendererText, from which it is derived. But while CellRendererText offers a simple entry to edit the text, CellRendererCombo offers a ComboBox or ComboBoxEntry widget to edit the text. The values to display in the combo box are taken from the tree model specified in the model property.

The combo cell renderer takes care of adding a text cell renderer to the combo box and sets it to display the column specified by its text_column property. Further cell renderers can be added in a handler for the editing_started signal.

Glib::PropertyProxy< bool > Gtk::CellRendererCombo::property_has_entry | ( |  | ) |

If FALSE, don't allow to enter strings other than the chosen ones.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< bool > Gtk::CellRendererCombo::property_has_entry | ( |  | ) | const

If FALSE, don't allow to enter strings other than the chosen ones.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< Glib::RefPtr<Gtk::TreeModel> > Gtk::CellRendererCombo::property_model | ( |  | ) |

The model containing the possible values for the combo box.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Gtk::TreeModel> > Gtk::CellRendererCombo::property_model | ( |  | ) | const

The model containing the possible values for the combo box.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< int > Gtk::CellRendererCombo::property_text_column | ( |  | ) |

A column in the data source model to get the strings from.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< int > Gtk::CellRendererCombo::property_text_column | ( |  | ) | const

A column in the data source model to get the strings from.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::SignalProxy2< void,const Glib::ustring&,const TreeModel::iterator& > Gtk::CellRendererCombo::signal_changed | ( |  | ) |

Slot Prototype:
  `void on_my_changed(const Glib::ustring& path, const TreeModel::iterator& iter)`

This signal is emitted each time after the user selected an item in the combo box, either by using the mouse or the arrow keys. Contrary to GtkComboBox, GtkCellRendererCombo::changed is not emitted for changes made to a selected item in the entry. The argument new_iter corresponds to the newly selected item in the combo box and it is relative to the GtkTreeModel set via the model property on GtkCellRendererCombo.

Note that as soon as you change the model displayed in the tree view, the tree view will immediately cease the editing operating. This means that you most probably want to refrain from changing the model until the combo cell renderer emits the edited or editing_canceled signal.

Since gtkmm 2.14:

Parameters

  path_string | A string of the path identifying the edited cell (relative to the tree view model).
  new_iter | The new iter selected in the combo box (relative to the combo box model).

## Friends And Related Function Documentation

related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.
