Rhino viewport event

In Rhino view properties tab, the name of the active view and other settings changed automatically when the viewport changed
What is the event used and how to use it in c#?

Hi @anon39580149,

There are a number of RhinoView events you can subscribe to:


RhinoView.Modified is probably what you want.

Hi @dale
Thank you, i don’t find an example how to use RhinoView.Modified ,
and in Visual studio activeview don’t have Modified


Maybe like this?

Hi @anon39580149,

Maybe this?

public class TestSeghier : Command
  public TestSeghier()
    Instance = this;
    RhinoView.SetActive += OnViewSetActive;
    RhinoView.Modified += OnViewModified;

  public static TestSeghier Instance { get; private set; }

  public override string EnglishName => "TestSeghier";

  private static void OnViewSetActive(object sender, ViewEventArgs args)
    RhinoApp.WriteLine(">> RhinoView.SetActive");

  private static void OnViewModified(object sender, ViewEventArgs args)
    RhinoApp.WriteLine(">> RhinoView.Modified");

  protected override Result RunCommand(RhinoDoc doc, RunMode mode)
    return Result.Success;

Thank you very much @dale
I will test it

Use the ViewEventArgs parameter passed to the events to get information about which view you are being informed about

Thanks @stevebaer
The script of @dale works great

I use RhinoView event with Rhinoinside to get activeview in Grasshopper.
I will try more events
