 * GtkTextClass:
 * @parent_class: The parent class.
 * @activate: Class handler for the #GtkText::activate signal. The default
 *   implementation activates the gtk.activate-default action.
 * @move_cursor: Class handler for the #GtkText::move-cursor signal. The
 *   default implementation specifies the standard #GtkText cursor movement
 *   behavior.
 * @insert_at_cursor: Class handler for the #GtkText::insert-at-cursor signal.
 *   The default implementation inserts text at the cursor.
 * @delete_from_cursor: Class handler for the #GtkText::delete-from-cursor
 *   signal. The default implementation deletes the selection or the specified
 *   number of characters or words.
 * @backspace: Class handler for the #GtkText::backspace signal. The default
 *   implementation deletes the selection or a single character or word.
 * @cut_clipboard: Class handler for the #GtkText::cut-clipboard signal. The
 *   default implementation cuts the selection, if one exists.
 * @copy_clipboard: Class handler for the #GtkText::copy-clipboard signal. The
 *   default implementation copies the selection, if one exists.
 * @paste_clipboard: Class handler for the #GtkText::paste-clipboard signal.
 *   The default implementation pastes at the current cursor position or over
 *   the current selection if one exists.
 * @toggle_overwrite: Class handler for the #GtkText::toggle-overwrite signal.
 *   The default implementation toggles overwrite mode and blinks the cursor.
 * @insert_emoji: Class handler for the #GtkText::insert-emoji signal.
 *
 * Class structure for #GtkText. All virtual functions have a default
 * implementation. Derived classes may set the virtual function pointers for the
 * signal handlers to %NULL, but must keep @get_text_area_size and
 * @get_frame_size non-%NULL; either use the default implementation, or provide
 * a custom one.
