ComboBoxTextRef

public struct ComboBoxTextRef : ComboBoxTextProtocol, GWeakCapturing

A GtkComboBoxText is a simple variant of GtkComboBox that hides the model-view complexity for simple text-only use cases.

To create a GtkComboBoxText, use gtk_combo_box_text_new() or gtk_combo_box_text_new_with_entry().

You can add items to a GtkComboBoxText with gtk_combo_box_text_append_text(), gtk_combo_box_text_insert_text() or gtk_combo_box_text_prepend_text() and remove options with gtk_combo_box_text_remove().

If the GtkComboBoxText contains an entry (via the “has-entry” property), its contents can be retrieved using gtk_combo_box_text_get_active_text(). The entry itself can be accessed by calling gtk_bin_get_child() on the combo box.

You should not call gtk_combo_box_set_model() or attempt to pack more cells into this combo box via its GtkCellLayout interface.

GtkComboBoxText as GtkBuildable

The GtkComboBoxText implementation of the GtkBuildable interface supports adding items directly using the <items> element and specifying <item> elements for each item. Each <item> element can specify the “id” corresponding to the appended text and also supports the regular translation attributes “translatable”, “context” and “comments”.

Here is a UI definition fragment specifying GtkComboBoxText items:

<object class="GtkComboBoxText">
  <items>
    <item translatable="yes" id="factory">Factory</item>
    <item translatable="yes" id="home">Home</item>
    <item translatable="yes" id="subway">Subway</item>
  </items>
</object>

CSS nodes

(plain Language Example):

combobox
╰── box.linked
    ├── entry.combo
    ├── button.combo
    ╰── window.popup

GtkComboBoxText has a single CSS node with name combobox. It adds the style class .combo to the main CSS nodes of its entry and button children, and the .linked class to the node of its internal box.

The ComboBoxTextRef type acts as a lightweight Swift reference to an underlying GtkComboBoxText instance. It exposes methods that can operate on this data type through ComboBoxTextProtocol conformance. Use ComboBoxTextRef only as an unowned reference to an existing GtkComboBoxText instance.
