superclass for all geometric transformations
a simple event forwarder command
Superclass for algorithms that produce only graph as output.
abstract superclass for all graph layout strategies
layout a graph in 2 or 3 dimensions
virtual int IsLayoutComplete()
Ask the layout algorithm if the layout is complete.
void SetLayoutStrategy(vtkGraphLayoutStrategy *strategy)
The layout strategy to use during graph layout.
vtkMTimeType GetMTime() override
Get the modification time of the layout algorithm.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkEventForwarderCommand * EventForwarder
This intercepts events from the strategy object and re-emits them as if they came from the layout eng...

static vtkGraphLayout * New()
~vtkGraphLayout() override
virtual void SetTransform(vtkAbstractTransform *t)
Transform the graph vertices after the layout.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
