Question

我已经看过像this one这样的问题了，但是我想使用的停靠库必须有一个重要的功能，没有被问到：它必须支持MVVM。

那么，在Telerik，DotNetBar，DevZest和其他库（不包括我已经测试过的AvalonDock）中，有没有你真正使用MVVM？

提前致谢

你好迈克试试这个：

简单方法：实施Sofa, An adaptation of AvalonDock for Prism

使用AvalonDock并实现这样的自定义区域适配器：

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();
}    
}

你在XAML中可以像这样实现它：

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

它是如何工作的？很简单，首先你必须记住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.

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

所以，按照这个例子你可以为avalon实现一个自定义区域适配器，我在一个项目中使用了这个实现，获得了很棒的结果。

此致
