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.

Deprecated:: 4.10: Use Gtk::DropDown instead.

The ComboBox widget looks like this:

Member Function Documentation

◆ get_active() [1/2]

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

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

Returns: The iterator.

◆ get_active() [2/2]

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

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

Returns: The iterator.

◆ get_active_id()

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 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 property_id_column() property of combo_box is not set, or if no row is active, or if the active row has a nullptr ID value, then nullptr is returned.

Deprecated: 4.10: Use Gtk::DropDown

Returns: The ID of the active row.

◆ get_active_row_number()

int Gtk::ComboBox::get_active_row_number ( ) const

Returns the index of the currently 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.

Deprecated: 4.10: Use Gtk::DropDown

◆ signal_changed()

Glib::SignalProxy< void()> Gtk::ComboBox::signal_changed ( )

Slot Prototype:: void on_my_changed()

Flags: Run Last

Emitted when the active item is changed.

The can be due to the user selecting a different item from the list, or due to a call to Gtk::ComboBox::set_active_iter(). It will also be emitted while typing into the entry of a combo box with an entry.

◆ signal_format_entry_text()

Emitted to allow changing how the text in a combo box's entry is displayed.

See property_has_entry().

Connect a signal handler which returns an allocated string representing path. That string will then be used to set the text in the combo box's entry. The default signal handler uses the text from the property_entry_text_column() model column.

Here's an example signal handler which fetches data from the model and displays it in the entry.

[C example ellipted]

Parameters

path	The Gtk::TreePath string from the combo box's current model to format text for.

Returns: A newly allocated string representing path for the current Gtk::ComboBox model.

◆ unset_active()
