Combining LocalView and RemoteView - issue after update

[juanprietob]

A reference to the previous issue

The video describes the steps to reproduce the bug/issue.

1. The app displays an Ultrasound video on the left side and a series of 3D renderers.
2. I want to dynamically add components to the 3D renderer.
3. When I add a component (plane) to the renderer, the image view stops working.
4. After a resize event of the window or similar event, the image viewer starts working again.

The ImageViewer is running as a VtkRemoteView and the Renderer is a vtkLocalView (see previous issue).

What is the correct way to update a Local or a Remote view?

3. Which view local or remote?

The correct way to update any view (local or remote) is to call the html_view.update() method on them. Keep in mind you can use the controller to centralize those calls more easily.

with vtk_widgets.VtkRemoteView(rw_1) as view:
    ctrl.view_update.add(view.update)

with vtk_widgets.VtkLocalView(rw_2) as view:
    ctrl.view_update.add(view.update)

# update both views
ctrl.view_update()

This did it!

Thank you so much for your help

ok, I finally saw what you meant in your video... ;-)
Not sure why the remote view stoped working after you added something in the scene...

Could you provide more information on what you did to add that plane? Did you rebuild the UI? If so that could explain why you got a glitch on the widget. Otherwise, it is hard to tell.
