vtkHandleRepresentation

Section: Visualization Toolkit Widget Classes

Usage

This class defines an API for widget handle representations. These representations interact with vtkHandleWidget. Various representations can be used depending on the nature of the handle. The basic functionality of the handle representation is to maintain a position. The position is represented via a vtkCoordinate, meaning that the position can be easily obtained in a variety of coordinate systems.

Optional features for this representation include an active mode (the widget appears only when the mouse pointer is close to it). The active distance is expressed in pixels and represents a circle in display space.

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

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

  obj = vtkHandleRepresentation
