[vtkusers] vtkPointWidget

[Matthias Riechmann]

Hi,

can anybody give me a code snippet how to add a vtkPointWidget to be 
able to move in around using the mouse? My problem: After adding it to 
the scene the same way I did it before when using the sphere- or 
line-widget I cannot see it on the screen. As a result it's not possible 
to use it interactively. My code (okay, this is for using line widget, 
but there shouldn't be much of a difference, should it?):

	drillChannel->lineWidget = vtkLineWidget::New();
	drillChannel->lineWidget->SetPoint1(point1);
	drillChannel->lineWidget->SetPoint2(point2);
	drillChannel->lineWidget->KeyPressActivationOff();
	drillChannel->lineWidget->SetInteractor(this->interactor);
	drillChannel->lineWidget->SetHandleRadius(1.0);
	drillChannel->lineWidget->On();

Do I have to follow special protocols when using the point-widget? I'm 
using vtk 5.0.3.


Matthias
