[vtk-developers] addition to vtkImagePlaneWidget - design ques.

[Dean Inglis]

Hi,

I've commited the changes to enable vtkImagePlaneWidget to
offer the code driven update of its underlying geometry,
vtkPlaneSource, by inheriting from vtkPolyDataSourceWidget.
Two new methods:

vtkPolyDataSource *vtkImagePlaneWidget::GetPolyDataSource()
{
  return this->PlaneSource;
}

void vtkImagePlaneWidget::UpdatePlacement(void)
{
  this->PlaneSource->Update();
  this->PositionHandles();
  this->UpdateNormal();
  this->UpdateOrigin();
  this->UpdateMargins();
}

Dean
