Detailed Description

abstract class for representing affine transformation widgets

This class defines an API for affine transformation widget representations. These representations interact with vtkAffineWidget. The basic functionality of the affine representation is to maintain a transformation matrix.

This class may be subclassed so that alternative representations can be created. The class defines an API and a default implementation that the vtkAffineWidget interacts with to render itself in the scene.

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).

virtual void vtkAffineRepresentation::GetTransform ( vtkTransform * t ) [pure virtual]

Retrieve a linear transform characterizing the affine transformation generated by this widget. This method copies its internal transform into the transform provided. The transform is relative to the initial placement of the representation (i.e., when PlaceWidget() is invoked).

Implemented in vtkAffineRepresentation2D.

virtual void vtkAffineRepresentation::SetTolerance ( int ) [virtual]

The tolerance representing the distance to the widget (in pixels) in which the cursor is considered near enough to the widget to be active.

virtual int vtkAffineRepresentation::GetTolerance ( ) [virtual]

The tolerance representing the distance to the widget (in pixels) in which the cursor is considered near enough to the widget to be active.

virtual void vtkAffineRepresentation::ShallowCopy ( vtkProp * prop ) [virtual]

Methods to make this class properly act like a vtkWidgetRepresentation.

Reimplemented from vtkWidgetRepresentation.

Reimplemented in vtkAffineRepresentation2D.
