ComboBox

A GtkComboBox is a widget that allows the user to choose from a list of valid choices.

An example GtkComboBox

The GtkComboBox displays the selected choice; when activated, the GtkComboBox displays a popup which allows the user to make a new choice.

The GtkComboBox 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 GtkComboBox implements the [interface@Gtk.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 [property@Gtk.ComboBox:has-entry] property allows the GtkComboBox to contain a [class@Gtk.Entry]. This entry can be accessed by calling [method@Gtk.ComboBox.get_child] on the combo box.

For a simple list of textual choices, the model-view API of GtkComboBox can be a bit overwhelming. In this case, [class@Gtk.ComboBoxText] offers a simple alternative. Both GtkComboBox and GtkComboBoxText can contain an entry.

CSS nodes

│       ╰── box
│           ├── cellview
│           ╰── arrow
╰── window.popup

A normal combobox contains a box with the .linked class, a button with the .combo class and inside those buttons, there are a cellview and an arrow.

│           ╰── arrow
╰── window.popup

A GtkComboBox with an entry has a single CSS node with name combobox. It contains a box with the .linked class. That box contains an entry and a button, both with the .combo class added. The button also contains another node with name arrow.

GtkComboBox uses the %GTK_ACCESSIBLE_ROLE_COMBO_BOX role.
