Hi Pedro,
You can use the Undo/Redo mechanism by defining an operation event for each
action. You'll need one operation for Undo and one operation for Redo.
//specify the undo operation with the edited slice
m_doOperation = new MyOperation();
//specify the undo operation with the non-edited slice
m_undoOperation = new MyOperation();
Where MyOperation is derived from mitk::Operation. There's also a need to have
a class that executes the operation when Undo() or Redo() is called on
UndoController. This is going to be derived from mitk::OperationActor. Then put
everything together in an mitk::OperationEvent.
//create an operation event for the undo stack
OperationEvent* undoStackItem = new OperationEvent(
MyOperationApplier::GetInstance(), m_doOperation, m_undoOperation,
"Segmentation" );
And add it to the UndoController:
//add it to the undo controller
UndoController::GetCurrentUndoModel()->SetOperationEvent( undoStackItem );
Have a look at mitkSegTool2D to see how Undo/Redo is done for mitk tools.
Hope this helps.
Regards
Tobi

Betreff: [mitk-users] Undo Controller
Hi,
can someone explain me how can I use the mitkUndoController? I've looked into
the Interaction and Undo/Redo Concepts
(http://docs.mitk.org/nightly-qt4/InteractionPage.html), but I can't really
understand how can I use the undo controller. Also, I'd like to know if the
undo controller also works with the mitk tools
Thanks in advance.
