Detailed Description

lays out tree in stacked boxes or rings

Performs a tree ring layout or "icicle" layout on a tree. This involves assigning a sector 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).

This class may be assigned as the layout strategy to vtkAreaLayout.

Member Function Documentation

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

static int vtkStackedTreeLayoutStrategy::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 vtkAreaLayoutStrategy.

virtual int vtkStackedTreeLayoutStrategy::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.

void vtkStackedTreeLayoutStrategy::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 vtkAreaLayoutStrategy.

virtual void vtkStackedTreeLayoutStrategy::Layout ( vtkTree inputTree,
vtkDataArray sectorArray,
vtkDataArray sizeArray 
) [virtual]

Perform the layout of the input tree, and store the sector bounds of each vertex as a tuple (innerRadius, outerRadius, startAngle, endAngle) in a data array.

Implements vtkAreaLayoutStrategy.

virtual void vtkStackedTreeLayoutStrategy::LayoutEdgePoints ( vtkTree inputTree,
vtkDataArray sectorArray,
vtkDataArray sizeArray,
vtkTree edgeRoutingTree 
) [virtual]

Fill edgeRoutingTree with points suitable for routing edges of an overlaid graph.

Define whether to reverse the order of the tree stacks from low to high.

virtual void vtkStackedTreeLayoutStrategy::ReverseOff ( ) [virtual]

Define whether to reverse the order of the tree stacks from low to high.

The spacing of tree levels in the edge routing tree. Levels near zero give more space to levels near the root, while levels near one (the default) create evenly-spaced levels. Levels above one give more space to levels near the leaves.
