|
* @class vtkInteractorStyleTreeMapHover
|
|
* @brief An interactor style for a tree map view
|
|
*
|
|
*
|
|
* The vtkInteractorStyleTreeMapHover specifically works with pipelines
|
|
* that create a tree map. Such pipelines will have a vtkTreeMapLayout
|
|
* filter and a vtkTreeMapToPolyData filter, both of which must be passed
|
|
* to this interactor style for it to function correctly.
|
|
* This interactor style allows only 2D panning and zooming, and additionally
|
|
* provides a balloon containing the name of the vertex hovered over,
|
|
* and allows the user to highlight a vertex by clicking on it.
