Detailed Description

abstract superclass for all area layout strategies

All subclasses of this class perform a area layout on a tree. This involves assigning a region to each vertex in the tree, and placing that information in a data array with four components per tuple representing (innerRadius, outerRadius, startAngle, endAngle).

Instances of subclasses of this class may be assigned as the layout strategy to vtkAreaLayout

Thanks to Jason Shepherd from Sandia National Laboratories for help developing this class.

static

IsA()

virtual vtkTypeBool vtkAreaLayoutStrategy::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Reimplemented in vtkBoxLayoutStrategy, vtkSliceAndDiceLayoutStrategy, vtkSquarifyLayoutStrategy, vtkStackedTreeLayoutStrategy, and vtkTreeMapLayoutStrategy.

PrintSelf()

void vtkAreaLayoutStrategy::PrintSelf ( ostream &  os, vtkIndent  indent  )

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

Reimplemented in vtkBoxLayoutStrategy, vtkSliceAndDiceLayoutStrategy, vtkSquarifyLayoutStrategy, vtkStackedTreeLayoutStrategy, and vtkTreeMapLayoutStrategy.

Layout()

virtual void vtkAreaLayoutStrategy::Layout ( vtkTree *  inputTree, vtkDataArray *  areaArray, vtkDataArray *  sizeArray  )

pure virtual

Perform the layout of the input tree, and store the sector bounds of each vertex as a tuple in a data array.

For radial layout, this is (innerRadius, outerRadius, startAngle, endAngle). For rectangular layout, this is (xmin, xmax, ymin, ymax).

The sizeArray may be nullptr, or may contain the desired size of each vertex in the tree.

Implemented in vtkBoxLayoutStrategy, vtkSliceAndDiceLayoutStrategy, vtkSquarifyLayoutStrategy, and vtkStackedTreeLayoutStrategy.

LayoutEdgePoints()

virtual void vtkAreaLayoutStrategy::LayoutEdgePoints ( vtkTree *  inputTree, vtkDataArray *  areaArray, vtkDataArray *  sizeArray, vtkTree *  edgeRoutingTree  )

virtual

Reimplemented in vtkStackedTreeLayoutStrategy.

FindVertex()

virtual vtkIdType vtkAreaLayoutStrategy::FindVertex ( vtkTree *  tree, vtkDataArray *  array, float  pnt[2]  )

pure virtual

Returns the vertex id that contains pnt (or -1 if no one contains it)

Implemented in vtkTreeMapLayoutStrategy, and vtkStackedTreeLayoutStrategy.

SetShrinkPercentage()
