Member Function Documentation

bool mitk::SeedsInteractor::ExecuteAction	(	mitk::Action *	action,
		mitk::StateEvent const *	stateEvent
	)		`[protected, virtual]`

Method called in HandleEvent after Statechange.

look up which object method is associated to the given action and call the method

Each statechange has actions, which can be assigned by it's number. If you are developing a new statemachine, declare all your operations here and send them to Undo-Controller and to the Data. Object- and group-EventId can also be accessed through static methods from OperationEvent

Reimplemented from mitk::StateMachine.
