[vtkusers] vtkOrientationMarkerWidget: how to modify the color of the x y z labels?

[John Platt]

Hi,

The axes actor is the vtkProp derived object hosted by the widget -

vtkAxesActor* myAxesActor = vtkAxesActor::New();
vtkOrientationMarkerWidget* myAxesWidget =
vtkOrientationMarkerWidget::New();
myAxesWidget->SetOrientationMarker( myAxesActor );

HTH

John.

hi John,
ok, but I've not found how do I get access to the actor of the x-axis 
("myAxesActor" in your sample code) from an instance of 
vtkOrientationMarkerWidget?
