The base class for all commands that need to create/delete callbacks in some way. Fill m_callbacksToDelete with the CallbackIds you want to delete, and fill the m_callbacksToInsert array with the callbacks returned from AL::AL::event::EventScheduler::buildCallback. Within the undo/redo implementation of a mel command, simply call redoItImplementation. This method will destroy the callbacks requested, and insert the created callbacks. Once called, the values of the m_callbacksToDelete and m_callbacksToInsert will be swapped, therefore calling redoItImplementation again will undo the previous action. More...
