/**
 * Description
 * GtkEntryCompletion is an auxiliary object to be used in conjunction with
 * GtkEntry to provide the completion functionality. It implements the
 * GtkCellLayout interface, to allow the user to add extra cells to the
 * GtkTreeView with completion matches.
 * "Completion functionality" means that when the user modifies the text
 * in the entry, GtkEntryCompletion checks which rows in the model match
 * the current content of the entry, and displays a list of matches.
 * By default, the matching is done by comparing the entry text
 * case-insensitively against the text column of the model (see
 * gtk_entry_completion_set_text_column()), but this can be overridden with
 * a custom match function (see gtk_entry_completion_set_match_func()).
 * When the user selects a completion, the content of the entry is updated.
 * By default, the content of the entry is replaced by the text column of the
 * model, but this can be overridden by connecting to the ::match-selected signal
 * and updating the entry in the signal handler. Note that you should return
 * TRUE from the signal handler to suppress the default behaviour.
 * To add completion functionality to an entry, use gtk_entry_set_completion().
 * In addition to regular completion matches, which will be inserted into the
 * entry when they are selected, GtkEntryCompletion also allows to display
 * "actions" in the popup window. Their appearance is similar to menuitems,
 * to differentiate them clearly from completion strings. When an action is
 * selected, the ::action-activated signal is emitted.
