Detailed Description

abstract superclass for all tree map layout strategies

All subclasses of this class perform a tree map layout on a tree. This involves assigning a rectangular region to each vertex in the tree, and placing that information in a data array with four components per tuple representing (Xmin, Xmax, Ymin, Ymax).

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

Member Function Documentation

static int vtkTreeMapLayoutStrategy::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.

Reimplemented in vtkSquarifyLayoutStrategy, vtkSliceAndDiceLayoutStrategy, and vtkBoxLayoutStrategy.

virtual int vtkTreeMapLayoutStrategy::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 vtkAreaLayoutStrategy.

Reimplemented in vtkSquarifyLayoutStrategy, vtkSliceAndDiceLayoutStrategy, and vtkBoxLayoutStrategy.

static vtkTreeMapLayoutStrategy* vtkTreeMapLayoutStrategy::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkAreaLayoutStrategy.

Reimplemented in vtkSquarifyLayoutStrategy, vtkSliceAndDiceLayoutStrategy, and vtkBoxLayoutStrategy.

virtual vtkObjectBase* vtkTreeMapLayoutStrategy::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkAreaLayoutStrategy.

Reimplemented in vtkSquarifyLayoutStrategy, vtkSliceAndDiceLayoutStrategy, and vtkBoxLayoutStrategy.

vtkTreeMapLayoutStrategy* vtkTreeMapLayoutStrategy::NewInstance

(

)

const

Reimplemented from vtkAreaLayoutStrategy.

Reimplemented in vtkSquarifyLayoutStrategy, vtkSliceAndDiceLayoutStrategy, and vtkBoxLayoutStrategy.

void vtkTreeMapLayoutStrategy::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.

Reimplemented in vtkSquarifyLayoutStrategy, vtkSliceAndDiceLayoutStrategy, and vtkBoxLayoutStrategy.

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

Find the vertex at a certain location, or -1 if none found.

Implements vtkAreaLayoutStrategy.

void vtkTreeMapLayoutStrategy::AddBorder

(

float *

boxInfo

)
