Member Function Documentation

float mitk::MouseMovePointSetInteractor::CanHandleEvent ( StateEvent const * stateEvent ) const [virtual]

calculates how good the data, this statemachine handles, is hit by the event.

overwritten, cause we don't look at the boundingbox, we look at each point and want to accept mouse movement for setting points

overwritten cause this class can handle mouse move events!
