ComboBoxText
A GtkComboBoxText is a simple variant of GtkComboBox for text-only use cases.
GtkComboBoxText hides the model-view complexity of GtkComboBox.
To create a GtkComboBoxText, use ctor@Gtk.ComboBoxText.new or ctor@Gtk.ComboBoxText.new_with_entry.
You can add items to a GtkComboBoxText with method@Gtk.ComboBoxText.append_text, method@Gtk.ComboBoxText.insert_text or method@Gtk.ComboBoxText.prepend_text and remove options with method@Gtk.ComboBoxText.remove.
If the GtkComboBoxText contains an entry (via the property@Gtk.ComboBox:has-entry property), its contents can be retrieved using method@Gtk.ComboBoxText.get_active_text.
You should not call method@Gtk.ComboBox.set_model or attempt to pack more cells into this combo box via its iface@Gtk.CellLayout 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

╰── window.popupGtkComboBoxText 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.
