Описание

The GtkComboBox is a replacement for the GtkOptionMenu and GtkCombo widgets, providing a solution that allows the user to choose from a list of options.

A GtkComboBox implements the GtkCellLayout interface, that provides a number of useful methods for managing the contents, adopting a model-view pattern. The constructor can be associated with an optional GtkTreeModel, which can otherwise be added later with the set_model() method.

Alternatively, the new_text function creates a simple GtkComboBox and associated GtkListStore model. A GtkCellRendererText is also created and packed in the new combo box. In this simple combo box each list item is a text string that can be selected. The convenience methods append_text() , prepend_text() , insert_text() and remove_text() can be used to manage the contents of the GtkComboBox.
