void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int vtkIdType
Definition: vtkType.h:338
dynamic, self-adjusting array of double
abstract superclass for all graph layout strategies
int vtkTypeBool
Definition: vtkABI.h:69
a simple class to control print indentation
Definition: vtkIndent.h:33
abstract superclass for arrays of numeric data
Definition: vtkDataArray.h:49
tree layout strategy reminiscent of astronomical systems
RadiusMode
How are node sizes specified?
No node sizes specified... unit radius is assumed.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
A rooted tree data structure.
Definition: vtkTree.h:54
represent and manipulate 3D points
Definition: vtkPoints.h:33
virtual void Layout()=0
This is the layout method where the graph that was set in SetGraph() is laid out. ...
Only leaf node sizes specified... parents are calculated during layout.
