[vtkusers] R: R: About decoupling events

[Zampini Samuele]

I am writing in Python... I am attaching below the part of the code where I need to use the vtkInteractorStyleTrackballActor: could you help to fix this, please?

Thanks a lot,

Samuele.


        self.vmtkRenderer = vmtkrenderer.vmtkRenderer()

	# Comment or uncomment...
	# self.vmtkRenderer.Initialize()

        # setting RenderWindow to the already existing one in vtkda 
	if not self.vmtkRenderer.Renderer:
		self.vmtkRenderer.Renderer = VmtkGui.ren
		# self.vmtkRenderer.Renderer = self.ren_int
		self.vmtkRenderer.RenderWindow = self.vtkda.GetRenderWindow()
		self.vmtkRenderer.RenderWindow.AddRenderer(self.vmtkRenderer.Renderer)
		self.vmtkRenderer.RenderWindow.SetSize(self.vmtkRenderer.WindowSize[0],self.vmtkRenderer.WindowSize[1])
		self.vmtkRenderer.RenderWindow.SetPointSmoothing(self.vmtkRenderer.PointSmoothing)
		self.vmtkRenderer.RenderWindow.SetLineSmoothing(self.vmtkRenderer.LineSmoothing)
		self.vmtkRenderer.RenderWindow.SetPolygonSmoothing(self.vmtkRenderer.PolygonSmoothing)
		# Note that if I use the vtkGenericRenderWindowInteractor() I get image i the right window but I can not interact with it, while if I use the vtkRenderWindowInteractor() I get an image I can "elaborate" as I like, but it does not appear in the right window.
		self.vmtkRenderer.RenderWindowInteractor = vtk.vtkRenderWindowInteractor()
		# self.vmtkRenderer.RenderWindowInteractor = vtk.vtkGenericRenderWindowInteractor()

		self.vmtkRenderer.RenderWindowInteractor.SetRenderWindow(self.vtkda.GetRenderWindow())
		self.vmtkRenderer.RenderWindowInteractor.SetInteractorStyle(vtk.vtkInteractorStyleTrackballCamera())
		self.vmtkRenderer.RenderWindow.SetInteractor(self.vmtkRenderer.RenderWindowInteractor)

		# The following line should help to make the interactor shared properly between the ImagePlaneWidgets and the renderer. Actually, nothing happens.
		self.vmtkRenderer.RenderWindowInteractor.Initialize()

vtkInteractorStyleTrackballActor is a vtkInteractorStyle, which is a
property of the vtkRenderWindowInteractor().  You would call:

rwi->SetInteractorStyle(style);
