我正在开发一个项目，我需要创建自定义编辑器并为自定义代码文件使用投影缓冲区，我已经按照本文 https://joshvarty.wordpress.com/中的步骤创建了一个代码窗口2014/08/01/翻录-视觉-工作室-编辑器-分开-与-投影-缓冲区/

代码窗口图像

但是，我无法让代码窗口响应任何键输入，尽管使用拖放工作

该扩展是为 Visual Studio 2015 编写的，是否需要注意它们的任何额外步骤才能使代码窗口正常工作？

这是我正在使用的代码：

 public IWpfTextViewHost CreateEditor(string filePath, int start = 0, int end = 0, bool createProjectedEditor = false)
    {
        //IVsInvisibleEditors are in-memory represenations of typical Visual Studio editors.
        //Language services, highlighting and error squiggles are hooked up to these editors
        //for us once we convert them to WpfTextViews. 
        var invisibleEditor = GetInvisibleEditor(filePath);

        var docDataPointer = IntPtr.Zero;
        Guid guidIVsTextLines = typeof(IVsTextLines).GUID;

        ErrorHandler.ThrowOnFailure(invisibleEditor.GetDocData(
            fEnsureWritable: 1
            , riid: ref guidIVsTextLines
            , ppDocData: out docDataPointer));

        IVsTextLines docData = (IVsTextLines)Marshal.GetObjectForIUnknown(docDataPointer);

        //Create a code window adapter
        var codeWindow = _editorAdapter.CreateVsCodeWindowAdapter(VisualStudioServices.OLEServiceProvider);
        ErrorHandler.ThrowOnFailure(codeWindow.SetBuffer(docData));

        //Get a text view for our editor which we will then use to get the WPF control for that editor.
        IVsTextView textView;
        ErrorHandler.ThrowOnFailure(codeWindow.GetPrimaryView(out textView));

        _currentlyFocusedTextView = textView;


        RegisterDocument(filePath);


        var textViewHost = _editorAdapter.GetWpfTextViewHost(textView);

        return textViewHost;
    }
