* 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.
