 * @activate: Class handler for the #GtkEntry::activate signal. The default
 *   implementation calls gtk_window_activate_default() on the entry’s top-level
 *   window.
 * @move_cursor: Class handler for the #GtkEntry::move-cursor signal. The
 *   default implementation specifies the standard #GtkEntry cursor movement
 *   behavior.
 * @insert_at_cursor: Class handler for the #GtkEntry::insert-at-cursor signal.
 *   The default implementation inserts text at the cursor.
 * @delete_from_cursor: Class handler for the #GtkEntry::delete-from-cursor
 *   signal. The default implementation deletes the selection or the specified
 *   number of characters or words.
 * @backspace: Class handler for the #GtkEntry::backspace signal. The default
 *   implementation deletes the selection or a single character or word.
 * @cut_clipboard: Class handler for the #GtkEntry::cut-clipboard signal. The
 *   default implementation cuts the selection, if one exists.
 * @copy_clipboard: Class handler for the #GtkEntry::copy-clipboard signal. The
 *   default implementation copies the selection, if one exists.
 * @paste_clipboard: Class handler for the #GtkEntry::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 #GtkEntry::toggle-overwrite signal.
 *   The default implementation toggles overwrite mode and blinks the cursor.
 * @get_text_area_size: Calculate the size of the text area, which is its
 *   allocated width and requested height, minus space for margins and borders.
 *   This virtual function must be non-%NULL.
 * @get_frame_size: Calculate the size of the text area frame, which is its
 *   allocated width and requested height, minus space for margins and borders,
 *   and taking baseline and text height into account. This virtual function
 *   must be non-%NULL.
 *
 * Class structure for #GtkEntry. 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.
