class Gtk::ComboBoxText

Overview

A Gtk::ComboBoxText is a simple variant of Gtk::ComboBox for text-only use cases.

An example Gtk::ComboBoxText

Gtk::ComboBoxText hides the model-view complexity of Gtk::ComboBox.

To create a Gtk::ComboBoxText, use Gtk::ComboBoxText.new or Gtk::ComboBoxText#new_with_entry.

You can add items to a Gtk::ComboBoxText with Gtk::ComboBoxText#append_text, Gtk::ComboBoxText#insert_text or Gtk::ComboBoxText#prepend_text and remove options with Gtk::ComboBoxText#remove.

If the Gtk::ComboBoxText contains an entry (via the [property@Gtk.ComboBox:has-entry] property), its contents can be retrieved using Gtk::ComboBoxText#active_text.

You should not call Gtk::ComboBox#model= or attempt to pack more cells into this combo box via its Gtk::CellLayout interface.

Gtk::ComboBoxText as Gtk::Buildable

The Gtk::ComboBoxText implementation of the Gtk::Buildable interface supports adding items directly using the element and specifying elements for each item. Each 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 Gtk::ComboBoxText items:

WARNING ⚠️ The following code is in xml ⚠️

<object class="Gtk::ComboBoxText">
  <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

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

Gtk::ComboBoxText 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.

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def active_text : String | Nil #

Returns the currently active string in combo_box.

If no row is currently selected, nil is returned. If combo_box contains an entry, this function will return its contents (which will not necessarily be an item from the list).
