Detailed Description

provides trackball motion control.

Date:: 2000/12/10 20:08:40

Revision:: 1.14

vtkInteractorStyleTrackball is an implementation of vtkInteractorStyle that defines the trackball style. The trackball style can be thought of as a "grab and move" approach. That is, on mouse down a point on the object is grabbed, and then moving the mouse cause motion in proportion to the amount of motion. Note that the events that are bound by this class are the same as vtkInteractorStyle (which implements joystick mode), just the behavior is modified consistent with the trackball style of interaction.

Member Function Documentation

vtkInteractorStyleTrackball* vtkInteractorStyleTrackball::New ( ) [static]

This class must be supplied with a vtkRenderWindowInteractor wrapper or parent. This class should not normally be instantiated by application programmers.
Reimplemented from vtkInteractorStyle.

virtual const char* vtkInteractorStyleTrackball::GetClassName ( ) [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkInteractorStyle.

int vtkInteractorStyleTrackball::IsTypeOf ( const char * type ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkInteractorStyle.

virtual int vtkInteractorStyleTrackball::IsA ( const char * type ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkInteractorStyle.

vtkInteractorStyleTrackball* vtkInteractorStyleTrackball::SafeDownCast ( vtkObject * o ) [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkInteractorStyle.

void vtkInteractorStyleTrackball::PrintSelf ( ostream & os,

vtkIndent indent

) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkInteractorStyle.

virtual void vtkInteractorStyleTrackball::OnRightButtonDown ( int ctrl,

int shift,

int X,

int Y

) [virtual]

Concrete implementation of event bindings
Reimplemented from vtkInteractorStyle.

int shift,

int X,

int Y

) [virtual]

Reimplemented from vtkInteractorStyle.

int Y

) [virtual]

Reimplemented from vtkInteractorStyle.

virtual void vtkInteractorStyleTrackball::OnChar ( int ctrl,

int shift,

char keycode,

int repeatcount

) [virtual]

OnChar implements keyboard functions, but subclasses can override this behavior
Reimplemented from vtkInteractorStyle.

virtual void vtkInteractorStyleTrackball::SetActorModeToCamera ( ) [virtual]

External switching between actor and camera mode.

virtual void vtkInteractorStyleTrackball::SetActorModeToActor ( ) [virtual]

virtual int vtkInteractorStyleTrackball::GetActorMode ( ) [virtual]

virtual void vtkInteractorStyleTrackball::SetTrackballModeToTrackball ( ) [virtual]

External switching between joystick and trackball mode.

virtual void vtkInteractorStyleTrackball::SetTrackballModeToJoystick ( ) [virtual]

virtual int vtkInteractorStyleTrackball::GetTrackballMode ( ) [virtual]

virtual void vtkInteractorStyleTrackball::OnTimer ( void ) [virtual]

OnTimer calls RotateCamera, RotateActor etc which should be overridden by style subclasses.
Reimplemented from vtkInteractorStyle.
