Detailed Description

The UndoStackTransaction class helps to execute transactions on an UndoStack.

This class allows to use RAII on a librepcb::editor::UndoStack object to make its exception safety easier. The functionality is as follows:

• The ctor starts a new command group with librepcb::editor::UndoStack::beginCmdGroup().
• If necessary, the dtor aborts it with librepcb::editor::UndoStack::abortCmdGroup().
• append() redirects to librepcb::editor::UndoStack::appendToCmdGroup().
• commit() redirects to librepcb::editor::UndoStack::commitCmdGroup().
• abort() redirects to librepcb::editor::UndoStack::abortCmdGroup().
