Section: Visualization Toolkit Widget Classes

# Usage

This class is a concrete representation for the vtkBoxWidget2. It represents a box with seven handles: one on each of the six faces, plus a center handle. Through interaction with the widget, the box representation can be arbitrarily positioned in the 3D space.

To use this representation, you normally use the PlaceWidget() method to position the widget at a specified region in space.

To create an instance of class vtkBoxRepresentation, simply invoke its constructor as follows

      obj = vtkBoxRepresentation

# Methods

The class vtkBoxRepresentation has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkBoxRepresentation class.

- `string = obj.GetClassName ()` - Standard methods for the class.
- `int = obj.IsA (string name)` - Standard methods for the class.
- `vtkBoxRepresentation = obj.NewInstance ()` - Standard methods for the class.
- `vtkBoxRepresentation = obj.SafeDownCast (vtkObject o)` - Standard methods for the class.
- `obj.GetPlanes (vtkPlanes planes)` - Get the planes describing the implicit function defined by the box widget. The user must provide the instance of the class vtkPlanes. Note that vtkPlanes is a subclass of vtkImplicitFunction, meaning that it can be used by a variety of filters to perform clipping, cutting, and selection of data. (The direction of the normals of the planes can be reversed enabling the InsideOut flag.)
- `obj.SetInsideOut (int )` - Set/Get the InsideOut flag. This data memeber is used in conjunction with the GetPlanes() method. When off, the normals point out of the box. When on, the normals point into the hexahedron. InsideOut is off by default.
- `int = obj.GetInsideOut ()` - Set/Get the InsideOut flag. This data memeber is used in conjunction with the GetPlanes() method. When off, the normals point out of the box. When on, the normals point into the hexahedron. InsideOut is off by default.
- `obj.InsideOutOn ()` - Set/Get the InsideOut flag. This data memeber is used in conjunction with the GetPlanes() method. When off, the normals point out of the box. When on, the normals point into the hexahedron. InsideOut is off by default.
- `obj.InsideOutOff ()` - Set/Get the InsideOut flag. This data memeber is used in conjunction with the GetPlanes() method. When off, the normals point out of the box. When on, the normals point into the hexahedron. InsideOut is off by default.
- `obj.GetTransform (vtkTransform t)` - Retrieve a linear transform characterizing the transformation of the box. Note that the transformation is relative to where PlaceWidget() was initially called. This method modifies the transform provided. The transform can be used to control the position of vtkProp3D's, as well as other transformation operations (e.g., vtkTranformPolyData).
- `obj.SetTransform (vtkTransform t)` - Set the position, scale and orientation of the box widget using the transform specified. Note that the transformation is relative to where PlaceWidget() was initially called (i.e., the original bounding box).
- `obj.GetPolyData (vtkPolyData pd)` - Grab the polydata (including points) that define the box widget. The polydata consists of 6 quadrilateral faces and 15 points. The first eight points define the eight corner vertices; the next six define the -x,+x, -y,+y, -z,+z face points; and the final point (the 15th out of 15 points) defines the center of the box. These point values are guaranteed to be up-to-date when either the widget's corresponding InteractionEvent or EndInteractionEvent events are invoked. The user provides the vtkPolyData and the points and cells are added to it.
- `vtkProperty = obj.GetHandleProperty ()` - Get the handle properties (the little balls are the handles). The properties of the handles, when selected or normal, can be specified.
- `vtkProperty = obj.GetSelectedHandleProperty ()` - Get the handle properties (the little balls are the handles). The properties of the handles, when selected or normal, can be specified.
- `vtkProperty = obj.GetFaceProperty ()` - Get the face properties (the faces of the box). The properties of the face when selected and normal can be set.
- `vtkProperty = obj.GetSelectedFaceProperty ()` - Get the face properties (the faces of the box). The properties of the face when selected and normal can be set.
- `vtkProperty = obj.GetOutlineProperty ()` - Get the outline properties (the outline of the box). The properties of the outline when selected and normal can be set.
- `vtkProperty = obj.GetSelectedOutlineProperty ()` - Get the outline properties (the outline of the box). The properties of the outline when selected and normal can be set.
- `obj.SetOutlineFaceWires (int )` - Control the representation of the outline. This flag enables face wires. By default face wires are off.
- `int = obj.GetOutlineFaceWires ()` - Control the representation of the outline. This flag enables face wires. By default face wires are off.
- `obj.OutlineFaceWiresOn ()` - Control the representation of the outline. This flag enables face wires. By default face wires are off.
- `obj.OutlineFaceWiresOff ()` - Control the representation of the outline. This flag enables the cursor lines running between the handles. By default cursor wires are on.
- `obj.SetOutlineCursorWires (int )` - Control the representation of the outline. This flag enables the cursor lines running between the handles. By default cursor wires are on.
- `int = obj.GetOutlineCursorWires ()` - Control the representation of the outline. This flag enables the cursor lines running between the handles. By default cursor wires are on.
- `obj.OutlineCursorWiresOn ()` - Control the representation of the outline. This flag enables the cursor lines running between the handles. By default cursor wires are on.
- `obj.OutlineCursorWiresOff ()` - Switches handles (the spheres) on or off by manipulating the underlying actor visibility.
- `obj.HandlesOn ()` - Switches handles (the spheres) on or off by manipulating the underlying actor visibility.
- `obj.HandlesOff ()` - Switches handles (the spheres) on or off by manipulating the underlying actor visibility.
- `obj.PlaceWidget (double bounds[6])` - These are methods that satisfy vtkWidgetRepresentation's API.
- `obj.BuildRepresentation ()` - These are methods that satisfy vtkWidgetRepresentation's API.
- `int = obj.ComputeInteractionState (int X, int Y, int modify)` - These are methods that satisfy vtkWidgetRepresentation's API.
- `obj.StartWidgetInteraction (double e[2])` - These are methods that satisfy vtkWidgetRepresentation's API.
- `obj.WidgetInteraction (double e[2])` - These are methods that satisfy vtkWidgetRepresentation's API.
- `double = obj.GetBounds ()` - These are methods that satisfy vtkWidgetRepresentation's API.
- `obj.ReleaseGraphicsResources (vtkWindow )` - Methods supporting, and required by, the rendering process.
- `int = obj.RenderOpaqueGeometry (vtkViewport )` - Methods supporting, and required by, the rendering process.
- `int = obj.RenderTranslucentPolygonalGeometry (vtkViewport )` - Methods supporting, and required by, the rendering process.
- `int = obj.HasTranslucentPolygonalGeometry ()` - Methods supporting, and required by, the rendering process.
- `obj.SetInteractionState (int state)` - The interaction state may be set from a widget (e.g., vtkBoxWidget2) or other object. This controls how the interaction with the widget proceeds. Normally this method is used as part of a handshaking process with the widget: First ComputeInteractionState() is invoked that returns a state based on geometric considerations (i.e., cursor near a widget feature), then based on events, the widget may modify this further.
