Detailed Description

abstract class defines interface between the widget and widget representation classes

This class is used to define the API for, and partially implement, a representation for different types of widgets. Note that the widget representation (i.e., subclasses of vtkWidgetRepresentation) are a type of vtkProp; meaning that they can be associated with a vtkRenderer end embedded in a scene like any other vtkActor. However, vtkWidgetRepresentation also defines an API that enables it to be paired with a subclass vtkAbstractWidget, meaning that it can be driven by a widget, serving to represent the widget as the widget responds to registered events.

The API defined here should be regarded as a guideline for implementing widgets and widget representations. Widget behavior is complex, as is the way the representation responds to the registered widget events, so the API may vary from widget to widget to reflect this complexity.

Warning
The separation of the widget event handling and representation enables users and developers to create new appearances for the widget. It also facilitates parallel processing, where the client application handles events, and remote representations of the widget are slaves to the client (and do not handle events).

Reimplemented in vtkXYPlotRepresentation.

◆ SetRenderer()

virtual void vtkWidgetRepresentation::SetRenderer ( vtkRenderer ren)
virtual

Subclasses of vtkWidgetRepresentation must implement these methods.

This is considered the minimum API for a widget representation.

SetRenderer() - the renderer in which the representations draws itself.
Typically the renderer is set by the associated widget.
Use the widget's SetCurrentRenderer() method in most cases;
otherwise there is a risk of inconsistent behavior as events
and drawing may be performed in different viewports.
BuildRepresentation() - update the geometry of the widget based on its
current state.

WARNING: The renderer is NOT reference counted by the representation, in order to avoid reference loops. Be sure that the representation lifetime does not extend beyond the renderer lifetime.

◆ PlaceWidget()

virtual void vtkWidgetRepresentation::PlaceWidget ( double vtkNotUsedbounds[6])
inlinevirtual

The following is a suggested API for widget representations.

These methods define the communication between the widget and its representation. These methods are only suggestions because widgets take on so many different forms that a universal API is not deemed practical. However, these methods should be implemented when possible to insure that the VTK widget hierarchy remains self-consistent.

PlaceWidget() - given a bounding box (xmin,xmax,ymin,ymax,zmin,zmax), place
the widget inside of it. The current orientation of the widget
is preserved, only scaling and translation is performed.
StartWidgetInteraction() - generally corresponds to a initial event (e.g.,
mouse down) that starts the interaction process
with the widget.
WidgetInteraction() - invoked when an event causes the widget to change
appearance.
EndWidgetInteraction() - generally corresponds to a final event (e.g., mouse up)
and completes the interaction sequence.
ComputeInteractionState() - given (X,Y) display coordinates in a renderer, with a
possible flag that modifies the computation,
what is the state of the widget?
GetInteractionState() - return the current state of the widget. Note that the
value of "0" typically refers to "outside". The
interaction state is strictly a function of the
representation, and the widget/represent must agree
on what they mean.
Highlight() - turn on or off any highlights associated with the widget.
Highlights are generally turned on when the widget is selected.

Note that subclasses may ignore some of these methods and implement their own depending on the specifics of the widget.

◆ SetPlaceFactor()

virtual void vtkWidgetRepresentation::SetPlaceFactor ( double  )
virtual

Set/Get a factor representing the scaling of the widget upon placement (via the PlaceWidget() method).

Normally the widget is placed so that it just fits within the bounding box defined in PlaceWidget(bounds). The PlaceFactor will make the widget larger (PlaceFactor > 1) or smaller (PlaceFactor < 1). By default, PlaceFactor is set to 0.5.

◆ GetPlaceFactor()

virtual double vtkWidgetRepresentation::GetPlaceFactor ( )
virtual

◆ SetHandleSize()

virtual void vtkWidgetRepresentation::SetHandleSize ( double  )
virtual

Set/Get the factor that controls the size of the handles that appear as part of the widget (if any).

These handles (like spheres, etc.) are used to manipulate the widget. The HandleSize data member allows you to change the relative size of the handles. Note that while the handle size is typically expressed in pixels, some subclasses may use a relative size with respect to the viewport. (As a corollary, the value of this ivar is often set by subclasses of this class during instance instantiation.)

Methods to make this class behave as a vtkProp.

They are repeated here (from the vtkProp superclass) as a reminder to the widget implementor. Failure to implement these methods properly may result in the representation not appearing in the scene (i.e., not implementing the Render() methods properly) or leaking graphics resources (i.e., not implementing ReleaseGraphicsResources() properly).

◆ HasTranslucentPolygonalGeometry()

virtual int vtkWidgetRepresentation::HasTranslucentPolygonalGeometry ( )

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THESE METHODS OUTSIDE OF THE RENDERING PROCESS Does this prop have some translucent polygonal geometry? This method is called during the rendering process to know if there is some translucent polygonal geometry.

A simple prop that has some translucent polygonal geometry will return true. A composite prop (like vtkAssembly) that has at least one sub-prop that has some translucent polygonal geometry will return true. Default implementation return false.
