Hi there,
I would like to have a mitk::Tool subclass that can use seed points to run a
region growing algorithm on a per slice basis.
However, I'm not sure I understand how to do this. Each mitk::Tool is itself a
subclass of StateMachine, so when registered will receive events. When I
construct my mitk::Tool subclass, the constructor string parameter determines
the correct pattern of state machine. So, by way of example, the
mitkAddContourTool, inherits from mitkContourTool which specifies
PressMoveReleaseWithCTRLInversion, and in StateMachine.xml the transition graph
is defined, with certain actions.
Question 1: How do these action ID's get converted to method calls? In tools
like mitk::AddContourTool, the methods that are called are OnMousePressed,
OnMouseMoved etc.
In addition, the MITK Tutorial Step5.cpp suggests that I can create a point set
interactor, registered with the global interactor, which will add/remove
points.
Question 2: So, should I create a PointSetInteractor within my own subclass of
mitk::Tool? Which one will get the events first?
I also tried in my mitk::Tool subclass, specifying in the constructor the
pattern PressMoveReleaseWithCTRLInversion and implementing methods
OnMousePressed and OnInvertLogic. So, when OnMousePressed was triggered, I
could add points to the point set and they were visualised, but then when the
control key was pressed, I couldnt remove them as PointSet doesn't have a
remove method.
Question 3: So, does all interaction with a PointSet have to be done with an
interactor? I can't just remove points programmatically myself from within a
Tool?
Thanks as always
Matt
