有沒有辦法遍歷visual studio shell？

Question

有沒有辦法遍歷所有的Visual Studio WPF元素？我試圖瞭解如何在Visual Studio擴展的上下文中添加額外的按鈕+上下文菜單條目。

是的，我知道Tab Studios的存在。如果這不起作用，我不妨試試，如果這符合我的需求。但在這一點上，我只是好奇如何做到這一點。

這裏是我迄今爲止嘗試：

internal class EditorMargin1 : StackPanel, IWpfTextViewMargin 
    { 
     /// <summary> 
     /// Margin name. 
     /// </summary> 
     public const string MarginName = "EditorMargin1"; 

     /// <summary> 
     /// A value indicating whether the object is disposed. 
     /// </summary> 
     private bool isDisposed; 

     /// <summary> 
     /// Initializes a new instance of the <see cref="EditorMargin1"/> class for a given <paramref name="textView"/>. 
     /// </summary> 
     /// <param name="textView">The <see cref="IWpfTextView"/> to attach the margin to.</param> 
     public EditorMargin1(IWpfTextView textView) 
     { 
      this.ClipToBounds = true; 

      var parents = GetParentsRecursive(textView); 

      var start = 60; 

      var white = new SolidColorBrush(Color.FromRgb((byte)255, (byte)255, (byte)255)); 
      white.Freeze(); 

      foreach (var parentElement in parents) 
      { 
       start += 20; 
       var background = new SolidColorBrush(Color.FromRgb((byte)start, (byte)0, (byte)start)); 

       var changedColor = false; 

       var colorableControl = parentElement as Control; 
       if (colorableControl != null) 
       { 
        colorableControl.Background = background; 
        changedColor = true; 
       } 

       this.Children.Add(new Label() 
       { 
        Foreground = white, 
        Background = background, 
        Content = "Hello EditorMargin1 " + parentElement.GetType().FullName + " has changed color " + changedColor, 
       }); 
      } 
     } 

     private IEnumerable<DependencyObject> GetParentsRecursive(IWpfTextView textView) 
     { 
      var control = textView as DependencyObject; 
      while (control != null) 
      { 
       yield return control; 
       control = LogicalTreeHelper.GetParent(control); 
      }

我跑進去，從一個穿越點的問題，是我不能讓過去WpfTextViewHost。

有沒有人知道一種簡單的方法來遍歷窗口？

遍歷所有的Visual Studio WPF元素，你可以從System.Windows.Application.Current.MainWindow啓動和使用System.Windows.Media.VisualTreeHelper.GetChild遞歸。請參閱以下示例代碼Hide title bar in Visual Studio 2013。
