支持MVVM的WPF對接庫

Question

我已經看到了一些像this one這樣的問題，但是我想要使用的對接庫必須有一個重要的特性，它沒有被問到：它必須支持MVVM。

因此，在Telerik，DotNetBar，DevZest和其他庫周圍的其他庫（不包括我已經測試過的AvalonDock）中，有沒有實際與MVVM一起使用的庫？

在此先感謝

您好邁克嘗試這樣的：

1. 簡單的方法：實施Sofa, An adaptation of AvalonDock for Prism

2. 使用AvalonDock和實現自定義區域適配器是這樣的：

   public class ResizingPanelRegionAdapter : RegionAdapterBase<DockingManager> 
   { 
   public ResizingPanelRegionAdapter(IRegionBehaviorFactory factory) 
       : base(factory) 
   { 
   
   } 
   protected override IRegion CreateRegion() 
   { 
       return new AllActiveRegion(); 
   } 
   
   protected override void Adapt(IRegion region, DockingManager regionTarget) 
   { 
       region.Views.CollectionChanged += delegate(Object sender, NotifyCollectionChangedEventArgs e) 
       { 
        OnViewsCollectionChanged(sender, e, region, regionTarget); 
       }; 
   } 
   
   private void OnViewsCollectionChanged(object sender, NotifyCollectionChangedEventArgs e, IRegion region, DockingManager regionTarget) 
   { 
       if (e.Action == NotifyCollectionChangedAction.Add) 
       { 
        foreach (object item in e.NewItems) 
        { 
         UIElement view = item as UIElement; 
         if (view != null) 
         { 
          //Get 
          ResizingPanel resizingPanel = GetResizingPanel(regionTarget.Content); 
          resizingPanel.Background = Brushes.White; 
          DocumentPane document = GetDocumentPane(resizingPanel.Children); 
          //document.Background = Brushes.White; 
   
          DocumentContent newContentPane = new DocumentContent(); 
          newContentPane.Content = item; 
          var itemView = (item as IViewBase); 
          if (itemView != null) 
           newContentPane.Title = itemView.Title; 
          //When contentPane is closed remove the associated region 
          newContentPane.Closed += (contentPaneSender, args) => 
          { 
           region.Remove(item); 
           newContentPane.Content = null; 
          }; 
   
          document.Items.Add(newContentPane); 
   
          if (!resizingPanel.Children.Contains(document)) 
           resizingPanel.Children.Add(document); 
   
          regionTarget.Content = resizingPanel; 
   
          newContentPane.Activate(); 
          region.Activate(item); 
         } 
        } 
       } 
       else if (e.Action == NotifyCollectionChangedAction.Remove) 
       { 
   
       } 
   } 
   
   private DocumentPane GetDocumentPane(UIElementCollection collection) 
   { 
       foreach (object item in collection) 
       { 
        var documentPanel = item as DocumentPane; 
        if (documentPanel != null) 
         return documentPanel; 
       } 
       return new DocumentPane(); 
   } 
   
   private ResizingPanel GetResizingPanel(object content) 
   { 
       var resizingPanel = content as ResizingPanel; 
       if (resizingPanel != null) 
        return resizingPanel; 
       return new ResizingPanel(); 
   }  
   } 
   

和你在你的XAML中可以這樣實現它：

<avalon:DockingManager prism:RegionManager.RegionName="MainRegion"> 
</avalon:DockingManager> 

它是如何工作的？ 簡單，首先在所有你必須記住，Region adapters are responsible for creating a region and associating it with the control. This allows you to use the IRegion interface to manage the UI control contents in a consistent way.

而一個DockingManager is the core control in AvalonDock. It arranges contained panes, handles fly out panes and floating windows.

所以，下面這個例子中，你可能已經實現Avalon的自定義區域適配器，我在一個項目中此實現獲取工作令人敬畏的結果。
