[vtkusers] Switch off bounding box

[Deelip Menezes]

Paul,

To prevent the bounding box from displaying, I use the good old technique of
deriving my own interactor class and overiding the highlight functions to do
nothing. Here is my class.

class vtkMyInteractorStyleTrackballCamera : public
vtkInteractorStyleTrackballCamera
{
public:
	vtkMyInteractorStyleTrackballCamera() {};
	~vtkMyInteractorStyleTrackballCamera() {};

public:
	static vtkMyInteractorStyleTrackballCamera* New()
	{
		return new vtkMyInteractorStyleTrackballCamera;
	};
	virtual void HighlightActor2D(vtkActor2D* actor2D) {};
	virtual void HighlightProp(vtkProp* prop) {};
	virtual void HighlightProp3D(vtkProp3D* prop3D) {};
}; 

This works for me. Hope this helps.

Regards,

Deelip Menezes

Subject: [vtkusers] Switch off bounding box

In my mainline I do this

	pickCmd = vtkCallbackCommand::New();
	pickCmd->SetCallback(Fpm3D::PickCells);
	pickCmd->SetClientData(this);
	this->Interactor->AddObserver(vtkCommand::EndPickEvent, pickCmd);

In my pick function I do this

// static
void Fpm3D::PickCells(vtkObject *caller, unsigned long eid, void
*clientdata, void *calldata)

	// switch off bounding box
	vtkInteractorStyle *ptr;
	if (ptr =
vtkInteractorStyle::SafeDownCast(fpm3d->Interactor->GetInteractorStyle())) {
		ptr->HighlightProp(NULL);
	}

BUT the bounding box stays on. Its been asked many times before in the NG
why doesn't it work?

Thanks Paul Tait
