Visual Studio Extension: Track when new code window is opened?

I'm trying to write a Visual Studio Extension that tracks when a new code window is opened. I found a class IVsCodeWindowEvents that seems to provide listener methods for that:

public int OnNewView(IVsTextView pView)

However, I have a problem that I don't know how to register to listen to these events.

My class looks like this:

public sealed class VSTrackerPackage : Package, IVsCodeWindowEvents

In this class, I implement the OnNewView method, but how can I register this listener in my Initialize method?

Yes you can register for Visual Studio events via the DTE and more specifically DTE2.

First step is to get access from your Package via the Initialize method:

public sealed class VSTrackerPackage : Package
{
    DTE2 dte = GetService(typeof (DTE)) as DTE2;
}

At this point, I'd recommend attaching to the DocumentEvents.DocumentOpened event. From there you can check if it's a document you are interested in or not. You can also get the Window if you need to interact with it there:

_dte.Events.DocumentEvents.DocumentOpened += document =>
        {
            //double check this logic.
            if (document.Language != "C#")
                return;

            //do work


            //or - load window document.ActiveWindow.
        };

If it helps, I have an open source Visual Studio plugin (shameluss plug: pMixins ) that attaches to a number of VS events. Relevant class is on GitHub: https://github.com/ppittle/pMixins/blob/master/CopaceticSoftware.CodeGenerator.StarterKit/Infrastructure/VisualStudioEventProxy.cs. Class definition starts on line 243.
