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.

virtual const char* vtkAreaLayoutStrategy::GetClassName (  )  [virtual]

static int vtkAreaLayoutStrategy::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type 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 vtkObject.

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

virtual int 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 vtkObject.

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

static vtkAreaLayoutStrategy* vtkAreaLayoutStrategy::SafeDownCast ( vtkObject o  )  [static]

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

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 vtkObject.

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

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 NULL, or may contain the desired size of each vertex in the tree.

Implemented in vtkBoxLayoutStrategy, vtkSliceAndDiceLayoutStrategy, vtkSquarifyLayoutStrategy, and vtkStackedTreeLayoutStrategy.

virtual void vtkAreaLayoutStrategy::LayoutEdgePoints ( vtkTree inputTree,
vtkDataArray areaArray,
vtkDataArray sizeArray,
vtkTree edgeLayoutTree 
) [virtual]

Reimplemented in vtkStackedTreeLayoutStrategy.

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 vtkStackedTreeLayoutStrategy, and vtkTreeMapLayoutStrategy.

virtual void vtkAreaLayoutStrategy::SetShrinkPercentage ( double   )  [virtual]

virtual double vtkAreaLayoutStrategy::GetShrinkPercentage (  )  [virtual]
