Problem

You would like to change the name, or title, or a viewport using the the Rhino C/C++ SDK. For example, you would like to rename the “Front” viewport to say “Facade.”

Solution

To change the title of a viewport, use CRhinoViewport::SetName. A Rhino view contains a “main viewport” that fills the entire view client window. To get a view’s main viewport, you can call CRhinoView::MainViewport.

For example:

CRhinoView* view = RhinoApp().ActiveView();
if (view)
  view->MainViewport().SetName("Facade");
