Detailed Description

Helper class to connect Qt-based navigators to instances of Stepper.

The constructor has to be provided with the Navigator that wants to use the Stepper. The Navigator has to define the slots Refetch() and SetStepper(mitk::Stepper *). SetStepper will be called only once to pass the Stepper to the Navigator. When the values of the Stepper changes, Refetch() will be called. The Navigator can than ask the Stepper for its new values.

Warning:

The Navigator has to be aware that it might have caused the changes of the Stepper itself. So take care that no infinite recursion is created!
