ComboBoxText

open class ComboBoxText : ComboBox, ComboBoxTextProtocol

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 ComboBoxText type acts as a reference-counted owner of an underlying GtkComboBoxText instance. It provides the methods that can operate on this data type through ComboBoxTextProtocol conformance. Use ComboBoxText as a strong reference or owner of a GtkComboBoxText instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ComboBoxText instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkComboBoxText>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ComboBoxText instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkComboBoxText>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the ComboBoxText instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op
