* @class vtkInteractorStyleAreaSelectHover
|
|
* @brief An interactor style for an area tree view
|
|
*
|
|
*
|
|
* The vtkInteractorStyleAreaSelectHover specifically works with pipelines
|
|
* that create a hierarchical tree. Such pipelines will have a vtkAreaLayout
|
|
* filter which must be passed to this interactor style for it to function
|
|
* correctly.
|
|
* This interactor style allows only 2D panning and zooming,
|
|
* rubber band selection and provides a balloon containing the name of the
|
|
* vertex hovered over.
