pure virtual

◆ count()

virtual int ModelView::UndoStackInterface::count ( ) const

pure virtual

Implemented in ModelView::UndoStack.

Referenced by TEST_F().

◆ endMacro()

virtual void ModelView::UndoStackInterface::endMacro ( )

pure virtual

Implemented in ModelView::UndoStack.

Referenced by gui2::ImportDataEditorActions::onDeleteItem(), gui2::ImportDataEditorActions::onImportDialogRequest(), gui2::ImportDataEditorActions::onMergeCanvases(), and TEST_F().

◆ execute()

virtual void ModelView::UndoStackInterface::execute ( std::shared_ptr< AbstractItemCommand > command )

pure virtual

Executes the command, then pushes it in the stack for possible undo.

Current design relies on shared pointer. This is done a) to retrieve result of the command from another place b) to adapt the command for QUndoStack c) to bypass QUndoStack behavior which wants to have an ownership

Implemented in ModelView::UndoStack.
