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:

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 nullptr ID value, then nullptr is returned.

Since gtkmm 3.0:

Returns

The ID of the active row, or nullptr.

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 nullptr.

Rows having a nullptr 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 nullptr.

Returns

true if a row with a matching ID was found. If a nullptr 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.

Deprecated: 3.10

Deprecated:

No replacement available.

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

void Gtk::ComboBox::set_focus_on_click

(

bool

focus_on_click = true

Sets the model column which combo_box should use to get string IDs for values from.

The column id_column in the model of combo_box must be of type TYPE_STRING.

Since gtkmm 3.0:

Parameters

id_column

A column in model to get string IDs for values from.

void Gtk::ComboBox::set_model

(

const Glib::RefPtr< TreeModel >&

model

)

Sets the model used by combo_box to be model.

Will unset a previously set model (if applicable). Use unset_model() to unset the old model.

Note that this function does not clear the cell renderers, you have to call Gtk::CellLayout::clear() yourself if you need to set up different cell renderers for the new model.

Since gtkmm 2.4:

Parameters

model

A Gtk::TreeModel.

void Gtk::ComboBox::set_popup_fixed_width

(

Since gtkmm 3.0:

Parameters

fixed

Whether to use a fixed popup width.

void Gtk::ComboBox::set_row_separator_func

(

const SlotRowSeparator&

slot

)

Parameters

slot	The callback.

void Gtk::ComboBox::set_row_span_column

(

int

row_span

)

Sets the column with row span information for combo_box to be row_span.

The row span column contains integers which indicate how many rows an item should span.

const Glib::ustring &

title

)

Parameters

title

A title for the menu in tearoff mode.

int

width

Preferred number of columns.

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

(

)

Slot Prototype:

void on_my_changed()

The changed signal is 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.

Since gtkmm 2.4:

Glib::SignalProxy< Glib::ustring,const TreeModel::Path& > Gtk::ComboBox::signal_format_entry_text

(

)

Slot Prototype:

Glib::ustring on_my_format_entry_text(const TreeModel::Path& path)

For combo boxes that are created with an entry (See GtkComboBox:has-entry).

A signal which allows you to change how the text displayed in a combo box's entry is displayed.

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 GtkComboBox::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]

Since gtkmm 3.4:

Parameters

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

Returns

A newly allocated string representing path for the current GtkComboBox model.

void Gtk::ComboBox::unset_active

(

)

Causes no item to be active.

See also set_active().

void Gtk::ComboBox::unset_model

(

)

Since gtkmm 2.16:

void Gtk::ComboBox::unset_row_separator_func

(

)
