一个支持 MVVM 的 WPF 对接库

Question

我已经看到了this one之类的问题，但是我想使用的对接库必须有一个重要的特性，没有被问到：它必须支持MVVM。

那么，在 Telerik、DotNetBar、DevZest 和周围的其他库（不包括我已经测试过的 AvalonDock）中，您是否实际使用了 MVVM？

提前致谢

你好，迈克试试这个：

1. 简单方法：实现Sofa, An adaptation of AvalonDock for Prism

2. 使用 AvalonDock 并像这样实现自定义区域适配器：

   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();
   }    
   }
   

你可以在你的 XAML 中这样实现它：

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

它是如何工作的？ 很简单，首先你要记住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.

还有一个DockingManager is the core control in AvalonDock. It arranges contained panes, handles fly out panes and floating windows.

因此，按照这个示例，您可以为 avalon 实现一个自定义区域适配器，我在一个项目中使用此实现获得了非常好的结果。
