String

char* Filename;
vtkSetStringMacro(Filename);

Bool

vtkSetMacro(UseTransform, bool);
vtkGetMacro(UseTransform, bool);
vtkBooleanMacro(UseTransform, bool);

Normal Variable

vtkGetMacro(ZRange, double);
vtkSetMacro(ZRange, double);

Vector Variable

Defined as:

private:
  float Center[3];

Accessor/mutator:

vtkSetVector3Macro(Center, float);
vtkGetVector3Macro(Center, float);

Allows you to call like:

float center[3] = {1.0, 0.0, 0.0};
filter->SetCenter(center);

or

filter->SetCenter(1.0, 0.0, 0.0);

SetClampMacro

• Restrict a parameter to a range - vtkSetClampMacro

NotUsed

When a parameter of a function is not used, "unused paramter" warnings are produced. To fix this, change the function declaration from:

void SimpleView::BorderCallback(vtkObject *caller, unsigned long eventId, void* callData)

to

void SimpleView::BorderCallback(vtkObject *caller, unsigned long vtkNotUsed(eventId), void* callData)
