[vtkusers] Removing Actors

[Renato Cesar Pompeu]

I'm using a button to show/disappear an actor. 
Here's the code:
 
vtkCubeSource *cubo = vtkCubeSource::New();    cubo->SetXLength(14);    cubo->SetYLength(14);    cubo->SetZLength(14);    cubo->SetCenter(a/2,b/2,c/2);
  vtkPolyDataMapper *cuboMapper = vtkPolyDataMapper::New();    cuboMapper->SetInput(cubo->GetOutput());
  vtkActor *cubo1 = vtkActor::New();    cubo1->SetMapper(cuboMapper);    cubo1->GetProperty()->SetColor(0.52, 0.27, 0);    cubo1->GetProperty()->SetAmbient(0.2);    cubo1->GetProperty()->SetDiffuse(0.3);    cubo1->GetProperty()->SetSpecular(0.8);
 
if  (tbnCubo->Down) {                     // the button is down = the cube appears    VTK3->GetRenderer()->AddActor(cubo1);
}
else {                                           // the button is up = the cube disappears     VTK3->GetRenderer()->RemoveActor(cubo1);    VTK3->GetRenderer()->RemoveViewProp(cubo1);    VTK3->GetRenderer()->Clear();
}
cubo->Delete();cuboMapper->Delete();cubo1->Delete();
VTK3->Invalidate();
When the button is up the actor does not disappear.

Just a dumb question : is your outlineActor the same at each call or not ? … could you please provide us with more sourcecode (t least the code before your condition …) ?
Fred.

Hello All, 

How do I remove an individual actor from the scene? My code does not work. Someone help me? Thanks.
 if  (tbnIniciar->Down) {  VTK3->GetRenderer()->AddActor(outlineActor);  } else {    VTK3->GetRenderer()->RemoveActor(outlineActor);    VTK3->GetRenderer()->RemoveViewProp(outlineActor);    VTK3->GetRenderer()->Clear();   } VTK3->Invalidate();
