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
