Detailed Description

3D widget for manipulating a box

This 3D widget interacts with a vtkBoxRepresentation class (i.e., it handles the events that drive its corresponding representation). The representation is assumed to represent a region of interest that is represented by an arbitrarily oriented hexahedron (or box) with interior face angles of 90 degrees (i.e., orthogonal faces). The representation manifests seven handles that can be moused on and manipulated, plus the six faces can also be interacted with. The first six handles are placed on the six faces, the seventh is in the center of the box. In addition, a bounding box outline is shown, the "faces" of which can be selected for object rotation or scaling. A nice feature of vtkBoxWidget2, like any 3D widget, will work with the current interactor style. That is, if vtkBoxWidget2 does not handle an event, then all other registered observers (including the interactor style) have an opportunity to process the event. Otherwise, the vtkBoxWidget will terminate the processing of the event that it handles.

To use this widget, you generally pair it with a vtkBoxRepresentation (or a subclass). Variuos options are available in the representation for controlling how the widget appears, and how the widget functions.

Event Bindings:

By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):

If one of the seven handles are selected:
  LeftButtonPressEvent - select the appropriate handle
  LeftButtonReleaseEvent - release the currently selected handle
  MouseMoveEvent - move the handle
If one of the faces is selected:
  LeftButtonPressEvent - select a box face
  LeftButtonReleaseEvent - release the box face
  MouseMoveEvent - rotate the box
In all the cases, independent of what is picked, the widget responds to the
following VTK events:
  MiddleButtonPressEvent - translate the widget
  MiddleButtonReleaseEvent - release the widget
  RightButtonPressEvent - scale the widget's representation
  RightButtonReleaseEvent - stop scaling the widget
  MouseMoveEvent - scale (if right button) or move (if middle button) the widget

Event Bindings:

Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkBoxWidget2's widget events:

  vtkWidgetEvent::Select -- some part of the widget has been selected
  vtkWidgetEvent::EndSelect -- the selection process has completed
  vtkWidgetEvent::Scale -- some part of the widget has been selected
  vtkWidgetEvent::EndScale -- the selection process has completed
  vtkWidgetEvent::Translate -- some part of the widget has been selected
  vtkWidgetEvent::EndTranslate -- the selection process has completed
  vtkWidgetEvent::Move -- a request for motion has been invoked

Event Bindings:

In turn, when these widget events are processed, the vtkBoxWidget2 invokes the following VTK events on itself (which observers can listen for):

  vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
  vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
  vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)

Event Bindings:: This class, and the affiliated vtkBoxRepresentation, are second generation VTK widgets. An earlier version of this functionality was defined in the class vtkBoxWidget.

Member Function Documentation

◆ New()

static vtkBoxWidget2* vtkBoxWidget2::New ( )

static

Instantiate the object.

◆ IsTypeOf()

static int vtkBoxWidget2::IsTypeOf ( const char * type )

static

◆ IsA()

virtual int vtkBoxWidget2::IsA ( const char * name )

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 vtkAbstractWidget.

◆ SafeDownCast()

static vtkBoxWidget2* vtkBoxWidget2::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkBoxWidget2::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkAbstractWidget.

◆ NewInstance()

vtkBoxWidget2* vtkBoxWidget2::NewInstance ( ) const

◆ PrintSelf()

void vtkBoxWidget2::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 vtkAbstractWidget.

◆ SetRepresentation()

void vtkBoxWidget2::SetRepresentation ( vtkBoxRepresentation * r )

inline

Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene. Note that the representation is a subclass of vtkProp so it can be added to the renderer independent of the widget.

Definition at line 124 of file vtkBoxWidget2.h.

◆ SetTranslationEnabled()

virtual void vtkBoxWidget2::SetTranslationEnabled ( int )

virtual

Control the behavior of the widget (i.e., how it processes events). Translation, rotation, scaling and face movement can all be enabled and disabled. Scaling refers to scaling of the whole widget at once, (default is through right mouse button) while face movement refers to scaling of the widget one face (axis) at a time (default through grabbing one of the representation spherical handles).
