Inheritance diagram for gutz::RotateManipEvent:

gutz::ManipEventBase< Manip > gutz::Counted List of all members.

Detailed Description

Rotate Manip Event.

Rotates a manipulator about its center of rotation.

Definition at line 34 of file ManipEvents.h.

Event Handlers

bool startEvent (Manip *m, const MouseEvent &me)
 should be called on a Mouse-down event, starts the event

bool handleEvent (Manip *m, const MouseMoveEvent &mme)
 should be called when the mouse moves

void endEvent (Manip *m, const MouseEvent &me)
 called when the event is over, may or may not be on a Mouse-up event

bool tumble (Manip *m)
 repeat last event


Public Types

typedef Manip ManipType
 either a Camera or a Manip (LIGHT??)
