## Detailed Description

A text entry field with a dropdown list.

A ComboBoxEntry is a widget that allows the user to choose from a list of valid choices or enter a different value. It is very similar to a ComboBox, but it displays the selected value in an entry to allow modifying it.

In contrast to a ComboBox, the underlying model of a ComboBoxEntry must always have a text column (see set_text_column()), and the entry will show the content of the text column in the selected row. To get the text from the entry, use get_active_text().

The changed signal will be emitted while typing into a ComboBoxEntry, as well as when selecting an item from the ComboBoxEntry's list. Use get_active() to discover whether an item was actually selected from the list.

See also ComboBoxEntryText, which is specialised for a single text column.

To add and remove strings from the list, just modify the model using its data manipulation API. You can get the Entry by using get_child().

If you have special needs that go beyond a simple entry (e.g. input validation), it is possible to replace the child entry by a different widget using Gtk::Container::remove() and Gtk::Container::add().

The ComboBoxEntry widget looks like this:

Deprecated:
  Instead use ComboBox with has_entry = true.

## Constructor & Destructor Documentation

virtual Gtk::ComboBoxEntry::~ComboBoxEntry | ( |  | ) | `[virtual]`

Gtk::ComboBoxEntry::ComboBoxEntry | ( |  | ) |

Gtk::ComboBoxEntry::ComboBoxEntry | ( | const Glib::RefPtr< TreeModel >& | model,
|  | const TreeModelColumnBase& | text_column
| ) |  | `[explicit]`

Creates a new ComboBoxEntry which has an Entry as child and a list of strings as popup.

You can get the Entry from a ComboBoxEntry using get_entry(). To add and remove strings from the list, just modify model using its data manipulation API.

Parameters:

  model | A TreeModel.
  text_column | A column in model to get the strings from.

Gtk::ComboBoxEntry::ComboBoxEntry | ( | const Glib::RefPtr< TreeModel >& | model,
|  | int | text_column = `0`
| ) |  | `[explicit]`

Creates a new ComboBoxEntry which has an Entry as child and a list of strings as popup.

You can get the Entry from a ComboBoxEntry using get_entry(). To add and remove strings from the list, just modify model using its data manipulation API.

Parameters:

  model | A TreeModel.
  text_column | A column in model to get the strings from.

## Member Function Documentation

Glib::ustring Gtk::ComboBoxEntry::get_active_text | ( |  | ) | const

Returns the currently active string.

Returns:
  The currently active text.

Since gtkmm 2.14:

Reimplemented in Gtk::ComboBoxEntryText.

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

See also:
  Bin::get_child().

Reimplemented from Gtk::ComboBox.

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

See also:
  Bin::get_child().

Reimplemented from Gtk::ComboBox.

int Gtk::ComboBoxEntry::get_text_column | ( |  | ) | const

Returns the column which entry_box is using to get the strings from.

Since gtkmm 2.4:

Deprecated: 2.24: Use get_entry_text_column() instead

Returns:
  A column in the data source model of entry_box.

GtkComboBoxEntry* Gtk::ComboBoxEntry::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::ComboBox.

const GtkComboBoxEntry* Gtk::ComboBoxEntry::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::ComboBox.

Glib::PropertyProxy_ReadOnly<int> Gtk::ComboBoxEntry::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 that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<int> Gtk::ComboBoxEntry::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 property of the value, or receive notification when the value of the property changes.

void Gtk::ComboBoxEntry::set_text_column | ( | const TreeModelColumnBase& | text_column | ) | const

Sets the model column which entry_box should use to get strings from to be text_column.

Since gtkmm 2.4:

Deprecated: 2.24: Use set_entry_text_column() instead

Parameters:

  text_column | A column in model to get the strings from.

void Gtk::ComboBoxEntry::set_text_column | ( | int | text_column | ) | const

Sets the model column which entry_box should use to get strings from to be text_column.

Since gtkmm 2.4:

Deprecated: 2.24: Use set_entry_text_column() instead

Parameters:

  text_column | A column in model to get the strings from.
