The rviz interface cannot support mouse zoom in, zoom out, or rotate operations

[peter5232]

I have compiled the entire project, but the generated rviz module does not support mouse zoom in, zoom out, or rotate operations.

Yes, that's because ViewController is not added to the app.

Why not add ViewController? Is there any problem?

Do you know how to add ViewController? I want this project to support operations such as zooming in and out, but I don't know how to add this feature. Please help me!
