SetAutoNumContextCommand Class Reference

The SetAutoNumContextCommand class Undo/redo wrapper around one of QETProject's add*AutoNum() setters (conductor/element/folio numerotation counters). Placing an auto-numbered item advances one of these counters as a side effect; without this command the counter change sits outside the undo stack entirely, so undoing the placement removes the visible number but leaves the counter advanced, silently burning it.
